Addresses and Locations
This is a pre-defined "group" of layers provided by the Cuyahoga County GIS Department:
- Address Points: Individual address points. Primarily collected in 2006 as part of the Location Based Response System (LBRS) project, but continually updated.
- Cuyahoga County Facility: County-owned facilities.
This is a pre-defined group of layers provided by the Cuyahoga County GIS Department, including depictions of roads, railroads, and other transportation features. Varying amounts of detail are available depending on the map scale, and include:
- Roads by Jurisdiction: All roads, from major interstates to local municipal streets. Primarily collected in 2006 as part of the Location Based Response System (LBRS) project, but continually updated.
- Other Transportation: Railroads, Airports, and Bridge Decks.
The following layers are provided by the Cuyahoga County GIS Department.
Cleveland NeighborhoodsAlso known as Statistical Planning Areas, there are 34 neighborhoods in the city. The City of Cleveland and its partners use these neighborhood definitions to collect data and guide their planning efforts. (latest available data)
MunicipalitiesThis layer displays names and boundaries of Cuyahoga County communities.
School DistrictsThis layer shows the names and shaded polygons for school districts in Cuyahoga County.
Council DistrictsThe 11 districts of Cuyahoga County Council are shown as shaded polygons in this layer.
County BoundaryThis shows the boundary of Cuyahoga County, excluding the portion in Lake Erie.
Two individual layers comprise the Land Status layer group:
Probable Vacant Lot
The Probable Vacant Lot layer is maintained by Case Western Reserve University's Northeast Ohio Community and Neighborhood Data for Organizing (NEOCANDO/NST) data warehouse. "Vacant" in this context means an individual parcel without a structure. In addition to using County Fiscal Office appraisal records to define the land use type of "vacant," this data set incorporates other indicators such as demolition permits (Cleveland only), and building value = $0. Since some of these indicators are imprecise, the data set includes the disclaimer of "probable" vacant.
Source: This data is acquired through the NEO CANDO data information system of the Jack, Joseph and Morton Mandel School of Applied Social Sciences at Case Western Reserve University and is updated weekly.
A conservation easement is a legal restriction on the use of a particular property or portion thereof. A conservation easement should not be confused with other, common land use easements such as those for underground utilities, or the land area between the sidewalk and the street (tree lawn). Conservation easements typically restrict land development - such as the clearing of vegetation, extraction of minerals, building of structures, etc. - in perpetuity - on the designated portion of the property while the landowner continues to hold the benefits of owning the land. The property owner who grants the conservation easement often receives tax benefits.
Source: The National Conservation Easement Database (NCED) is a nationwide compilation of conservation easements. The NCED relies on the voluntary submittal of conservation easement data by participating organizations and is not necessarily an exhaustive list.
EnviroAtlas is an interactive web-based tool developed collaboratively in 2014 by USEPA in partnership with the U.S. Geological Survey (USGS), the U.S. Department of Agriculture (USDA), and other federal and non-profit organizations, universities, state, county, and city-level stakeholders. Regular updates to EnviroAtlas will occur through 2022.
The full EnviroAtlas Dynamic Data Matrix contains more than 400 layers of data. The main data categories include: nature & natural resources (including agriculture); EPA-regulated topics & pollution; human community; regional - ecological & political. Please note that the Greenprint displays just two of the data sets: Active Resource Conservation and Recovery Act (RCRA) and Superfund Sites.
An Active RCRA site simply means that the property owner has registered with EPA as either a Large Quantity Generator (LQG), or a facility which Treats, Transports, Stores or Disposes of hazardous waste under the Resource Conservation and Recovery Act program. These hazardous waste handlers may include facilities as large as industrial manufacturing sites or as small as dry cleaners and auto mechanic shops. Registration as a RCRA permitted site is an administrative requirement and does not imply contamination.
Superfund Sites are properties which have reported to EPA under the Superfund Enterprise Management System (SEMS) and SEMS National Priorities List (NPL). Superfund is a program administered by the EPA to locate, investigate, and clean up the worst hazardous substance contaminated sites throughout the United States under the Federal Comprehensive Emergency Response, Compensation and Liability Act. Such reporting may include known releases or threatened releases of hazardous substances, pollutants or contaminants.
Cuyahoga County Open Space Inventory consists of public and institutionally owned open space. Four general types are depicted:
- Public Park: Publicly accessible parks
- Golf Course: Both public and private
- Other Public/Institutional: Includes non-park open spaces such as airports, school campuses, and some publicly owned vacant land.
The Open Space Inventory does not necessarily include conservation easements on privately held lands.
Source: Cuyahoga County Open Space Inventory, 2014, Cuyahoga County Planning Commission. Originally developed as part of a multi-county inventory, the Cuyahoga County portion has been continually maintained and updated by the Cuyahoga County Planning Commission with input from the Cleveland Metroparks and the Cuyahoga Valley National Park. In recent years, the Open Space Inventory has been expanded to include smaller, integral open spaces in Cuyahoga County including all of the City of Cleveland's municipal parks and recreation centers.
Cuyahoga Greenway Network
The Cuyahoga Greenway Network is a system of interconnected trails that includes off-road all-purpose trails and on-road bikeway connections (bike lanes, sharrows and designated bicycle routes). The network is comprised of major and minor routes identified through a county-wide planning initiative undertaken by the Cuyahoga County Planning Commission, NOACA, and the Cleveland Metroparks. This Greenway Plan (completed 2019, adopted in 2020) depicts existing and planned routes of regional significance throughout the county. The routes typically traverse more than one community, fill gaps between identified regional routes, and create non-motorized transportation connections to destinations, employment centers and other activity centers. Planned trails and routes are depicted at a conceptual level and the exact placement could be adjusted once detailed design and engineering plans are underway.
Trails and bikeways which are more local within a given community can be viewed as Existing Off-Roand and Existing On-Road.
Trails and bikeways are categorized and depicted accordingly on the map:
- Critical Gaps: These are relatively short sections of future greenways or urban trails that fill "gaps" in the existing regional trail network. These gaps typically connect to existing trails or other non-motorized facilities at both ends.
- Regional Links: These reflect longer sections of the regional network. These routes typically connect to existing regional trails on at least one end, and connect to major population centers, employment hubs, recreational anchors, or link to other trails or activity hubs outside of Cuyahoga County.
- Key Routes: These are additional routes in the overall greenway network which can provide substantial benefit or other functions to the network.
Also displayed are:
- Existing Off-Road: These are existing trails of regional significance.
- Existing On-Road: These are existing routes or lanes of regional significance.
Source: The Cuyahoga Greenway Partners, a collaboration of trails advocates representing various agencies, regional organizations, and municipalities.
The Watersheds layer shows two depictions of watersheds:
- Local Watersheds: Each of the local watersheds are named and grouped according to their major watershed "parent"
- Local Watersheds by Percent Impervious: Watersheds are shaded according to their percentage impervious surface, a key indicator of watershed health that can guide future restoration efforts.
A watershed is a geographic region with rivers and streams that all drain into a larger, single named body of water. Hills and valleys direct water to the drainage basin, such as a river or lake. The action of a watershed can be viewed on a small scale, such as the area that drains into the creek behind a house. Or, watersheds can be large such as the range of land and streams that drain into the Ohio River or Lake Erie. (Ohio EPA)
Most of the watersheds in Cuyahoga County are supported and coordinated by local watershed stewardship groups, such as Friends of Euclid Creek or Doan Brook Watershed Partnership. These watershed stewardship groups can be contacted through hyperlinks available in the map.
The local watersheds available for viewing in the map are classified as a Hydrologic Unit Code (HUC) 12 of the National Hydrography Dataset, and have been modified slightly for local naming conventions and groupings. The HUC level indicates watershed size and HUC 12 is considered a local sub-watershed that includes tributary systems.

Local Watersheds, by Percent Impervious
The same, local watersheds are available for viewing in the map with a depiction of the amount of their land area covered by impervious surface - e.g. asphalt, buildings, and other hard-packed surfaces that prevent precipitation from percolating into the ground.
Information published by the Center for Watershed Protection has been incorporated into the watershed maps, developed a series of manuals with guidelines and practices for watersheds that correspond to their degree of impervious cover. The shadings and groupings shown in the Greenprint Viewer correspond to the guidelines in the Urban Subwatershed Restoration Manual Series Manual 1: An Integrated Framework to Restore Small Urban Watersheds. (see page 37), available as a downloadable PDF or through the CWP's online library.

Cuyahoga County is served by four major water systems or features: the three major river valleys of the Rocky, Cuyahoga and Chagrin Rivers and the lakeshore of Lake Erie. Tributaries to these water features typically reach from upland headwaters, down through a variety of dense urban land uses, and ultimately to Lake Erie.
Three water feature categories are depicted in separate sub-layers:
- Streams (Metroparks/CEGIS): These are the centerlines of smaller streams.
- Stream Labels and Underground Features (National Hydrography Dataset - NHD): This category identifies major above-ground streams by name, and shows underground water structures, such as water pipelines, that connect with other segments of above-ground streams and lakes.
- Water Bodies (Metroparks/CEGIS): This is an area representation of lakes, ponds, larger streams, and rivers. These water bodies were originally identified by 2006 aerial photography, and graphically enhanced by the Cleveland Metroparks GIS staff.
Wetlands are represented in a separate layer.
Source: Water features were compiled from two sources. Streams and Water Bodies were digitized by the Cuyahoga County IT Department from 2006 aerial photography images. Graphical enhancements to these data sets were provided by the Cleveland Metroparks. The Stream Labels feature names and representations of underground stream connections were provided by the National Hydrography Dataset (NHD, 2011), a product of the US Geologic Survey. Local data provides the highest level of graphic detail, while the NHD dataset provides a complex national network of water features, including names (where known) and the modeling of water flow.
Existing wetlands are depicted from two available sources, each in its own sub-layer. Wetland features from these two well-recognized inventories often overlap and vary in their coverage, due to varying methodologies and time. Each has a different set of characteristics, as well.
- National Wetlands Inventory: Each wetland in this inventory is assigned a brief "NWI Code" to summarize its typology. A brief description is provided for each code ("NWI Description"). To get a full descriptive definition for any particular code, see the NWI Wetlands Code Interpreter.
- Cuyahoga Soil & Water Conservation District: The SWCD Wetlands Inventory is actually a compilation of two studies, done in 2000 and 2006. This inventory provides the latest available inventory of locally identified wetlands. Note: several of these wetlands have since been destroyed due to development.
Sources: National Wetlands Inventory (NWI): The National Wetlands Inventory is a collection of inventories conducted throughout the United States under the direction of the US Fish & Wildlife Service. In Ohio, Ducks Unlimited, serving as a consultant to the US Fish & Wildlife Service, resurveyed wetlands throughout the State in 2009. For a detailed report on the data collection process, see Updating the National Wetlands Inventory (NWI) for Ohio (PDF).
The Cuyahoga Soil & Water Conservation District (SWCD) contracted with Davey Resources Group for two GIS-based surveys. The first was conducted in 2000 in the Cuyahoga River watershed (within Cuyahoga County). In 2006, a second GIS-based inventory was conducted for the balance of the county. The purpose of these studies was to provide general information on the locations and sizes of wetlands. The study authors advise that the inventories should not be used in place of a wetlands determination and/or delineation. If detailed size and wetlands boundary information is required, a proper wetlands delineation, including a wetlands boundary survey, should be performed by a qualified wetlands specialist. For the full report, see the GIS Wetlands Inventory and Restoration Assessment (PDF).
Water Feature Corridors
A riparian zone or riparian area is the interface between the land and a river, stream, wetland or shoreline.
There are several indicators available to help identify riparian zones. Two methods are used in the Cuyahoga County Greenprint:
- 100-Year Flood Plain: Flood plains are commonly used to gauge flooding potential, and as a proxy for low-lying riparian areas. The map of FEMA flood plain areas was updated for Cuyahoga County in 2010. A flood plain can be a hazard area for roads, buildings and human activities. FEMA flood insurance can be purchased (at different rates depending on the potential flood hazard) for a structure in a flood plain.
- Active Stream Area: Working with several partners, including the Cleveland Metroparks and the Chagrin River Watershed Partners, the Cuyahoga County Planning Commission (CCPC) developed a predictive series of buffer areas - areas to be preserved for protection - around various types of water features highlighted in the map. The methods utilized are patterned on well-established modeling approaches and use a particular feature's drainage area to delineate its buffer or active stream area.
The maps show buffered water areas, by feature, as determined by the CCPC:
- Lake Erie Shore: 300 feet buffer
- Navigable River (Cuyahoga): 300-foot buffer
- Navigable River (Chagrin, Rocky): 120-foot buffer
- Stream Bank (Larger Watershed): 120-foot buffer
- Stream Bank (Smaller Watershed): 75-foot buffer
- Ponds, Lakes, Other Water bodies: 120-foot buffer
- Wetland (National Wetland Inventory): 120-foot
- Wetland (Soil and Water Inventory): 120-foot
- Small Stream Centerline: 25 foot buffer
When viewing these modeled buffer areas on the map, users can click within any given buffer area and "View Details" to see the reasoning behind that particular buffer area size.
Note that these riparian buffers were generated only for above-ground water features and exclude culverted portions streams.

Priority Conservation Areas
Priority Conservation Areas (PCAs) are areas that are recognized as significant spaces to be preserved as open space. In Ohio, PCAs are locally selected and generally identified in a Balanced Growth Plan that has been approved by local communities and endorsed by the Ohio EPA. This is a voluntary designation and is specifically geared toward watershed protection under the Ohio Balanced Growth Program. While the Balanced Growth Planning process can result in identifying areas prioritized for development and for conservation, the Greenprint shows only the Priority Conservation Areas. Four approved Balanced Growth plans have been completed in portions of Cuyahoga County: Big Creek Watershed, Chagrin River Watershed, Chippewa Creek Watershed, and Furnace Run Watershed.
A PCA designates areas for protection and restoration that may be critically important as ecological, recreational, heritage, agricultural, and public access areas. They can also be significant for their contribution to water quality and general quality of life. Optionally, agricultural areas may be designated as Priority Agricultural Areas (PAA).
The PCA designation does not change the landowner's property rights, and the property is still subject to local land-use regulation. The land may be eligible for state funding incentives to support and encourage its use as a desirable area for conservation driven by state public policy that would not encourage or provide funding for development within the designated PCA.

Census Block Demographics
Census Blocks are generally the smallest geographic unit available from the U.S. Census Bureau, often representing city blocks in urbanized areas, and larger areas, longer than city blocks, in suburban and rural areas. Demographic data for these very small geographic units are available only in the decennial census, most recently the 2010 Census. Demographic information available for Census Blocks include population by Age, Race, and Hispanic Origin, as well as Housing Occupancy.
These demographic indicators are available in the Greenprint for individual blocks or in groups of blocks by using the Query tools (e.g. Polygon or Rectangle). Users can also see demographic information by using the Buffer Options. The Buffer Options can be found in the context menu for the Query results panel; available only after searching for other features.
Census data will be updated in the Greenprint with the release of 2020 Census data. Updates will be completed early in 2022.

Urban Tree Canopy Metrics
The Urban Tree Canopy Metrics layer group is based on the Cuyahoga County Urban Tree Canopy Assessment (UTC) first conducted in 2011 and updated in 2017. It has eight individual layers that display the following:
- Existing Canopy by Census Tract
- Existing Tree Canopy by Parcel
- Possible Canopy by Census Tract
- Possible Tree Canopy by Parcel
- Canopy Change by Census Tract
- Canopy Change by Parcel
- Existing Tree Canopy by Right-of-way*
- Canopy Change by Right of Way
- Possible Tree Canopy by Right of Way**
- Tree Canopy Change 2011-2017
*Right-of-way information is for continuous sections of same-street right-of-way in a municipality.
**Possible Tree Canopy right-of-way metrics are for pervious surfaces only.
Each layer provides a thematic summary of percentage of total land cover for the selected area.
- Existing Tree Canopy is defined as the layer of leaves, branches, and stems of trees that cover the ground when viewed from above.
- Potential Tree Canopy is considered the remaining (non-tree) portion, which could potentially be modified with the addition of trees to increase the tree canopy. These areas include vegetated, bare, and "other pavement" portions of land. Note that the potential tree canopy percentage may be low in areas containing large amounts of existing tree canopy and may be high in areas with large parking lots.
For the complete set of tree canopy metrics see the Urban Tree Canopy Assessment Update
Source: Cuyahoga County Planning Commission Urban Tree Canopy Assessment, originally published in 2013 and updated in 2019.
Land Cover can generally be considered the vegetation, water, natural and human-made surface of the earth. The land cover layer used in the Greenprint is the basis for the County's Urban Tree Canopy (UTC) Assessment Update, captured in 2017. High resolution land cover data is a key tool in not only "seeing" but also measuring natural resource patterns, especially in the densely built urban environment of Cuyahoga County. The land cover layer can be used as a "base" when highlighting green infrastructure issues.
The land cover data in the Greenprint was further analyzed through the UTC assessment and summarized by various geographic levels including city, neighborhood, and parcel levels. See the URBAN TREE CANOPY METRICS layer group for more detail on these geographic summaries.
The UTC assessment produced a classification system for ten classifications of land cover in Cuyahoga County:
- Grass/Shrub: Grass and low-lying shrubs
- Bare Soil: Exposed dirt, including beaches, baseball infields, and some agricultural fields
- Water: Visible water features
- Buildings: Exposed houses and buildings, generally excluding garages and other smaller structures
- Roads / Railroads: Exposed pavement within the public right of way, as well as railroad beds
- Other paved: Exposed pavement within private property, typically including parking lots and private roadways
- Tree Canopy over vegetation/ Bare Soil: Tree canopy extending over vegetation or bare earth
- Tree Canopy over Building: Tree canopy extending over buildings
- Tree Canopy over Road: Tree canopy extending over road / railroad
- Tree Canopy over Other Paved: Tree canopy extending over other paved surfaces
As measured in the UTC study, "Tree Canopy" includes classes 7, 8, 9, and 10.
Source: Cuyahoga County Planning Commission Urban Tree Canopy Assessment Update, 2019. The UTC land cover analysis was developed through the integration of several data sources - primarily from the National Agricultural Imagery Program (NAIP) 2011 and 2017, 4-band aerial imagery, US Department of Agriculture; as well as additional imagery, LIDAR elevation data, and other local data sources.
Tree Canopy Change (2011-2017)
Tree Canopy Change depicts the change in tree canopy on the surface of the land from 2011-2017:
- No Change shows areas that were covered by trees in 2011 and continue to be in 2017.
- Gain shows areas where the tree canopy coverage has expanded from 2011-2017. Most Gain has occurred in relatively small areas - due mostly to outgrowth of existing trees. New plantings are generally not reflected here, as a minimum height of eight feet is required to qualify as a "tree".
- Loss are areas where tree canopy had been present in 2011, but which has changed to some other type of land cover by 2017. Losses may be due to natural causes (age, disease, storms, etc.) or from development.

The Topography layer group contains two layers: Elevation Contours and Steep Slope, with each providing information about the shape and elevation of the ground surface.
Elevation contours are linear representations of the elevation of the ground. When the layer is enabled, contour lines will appear on the Greenprint as users zoom in to see the detailed line work.
Each continuous line represents a particular elevation value, and the lines are spaced at two-foot elevation intervals. Thicker index lines represent intervals of 10 feet and are automatically labeled with their elevation value. To find the elevation value of thinner lines, users can count individual lines in two-foot increments, adding or subtracting two feet from the nearest index line with an elevation value. Alternatively, users can click on the Identify tool for a given line and find its elevation value.
Contour lines that are spaced closely together on the map indicate steeper slopes, with elevation changing rapidly. Conversely, flatter areas will have very few lines in a given area and may not show a distinct contour line pattern.
Contours will often form circular patterns, such as around all sides of a hill. In that simple case, it is assumed that contour lines inside of others are rising in elevation. Dashed elevation lines represent depressions. Closed depressions will often occur around ponds, wetlands, or other such low-lying areas.
Other contextual clues can help in reading contour lines and the associated terrain. For example, the Shaded Relief layer (at the bottom of the layer list) illustrates shadows cast from a virtual sun shining from the northwest. Another example, using water features, generally occurs for lower elevations and may cause contour lines to stretch out in the downhill direction of the water's flow.
Elevation contours can also be used to effectively calculate slope (steepness) along a given path by dividing the change in elevation by the horizontal distance between any two points.
Source: Elevation contours were developed by Cuyahoga County from a 2006 aerial photography project. See Cuyahoga County GIS Data.
Steep Slope is a layer that depicts land having a percentage slope greater than 12%, shown in two classes: 12-18% and 18.1% or more.
Slope is measured as rise over run and is depicted here in percentage classes. For example, a stretch of land 100 feet long that rises fifteen feet in elevation has a slope of fifteen percent (15/100).
Planning and conservation literature cite varying definitions for "steep" slope. Considerations include soil type, land cover, and allowable landscape techniques. Hillside protection ordinances likewise cite varying standards, and often include slope-density standards that limit the density of development according to the degree of slope.
Source: Steep slope data was developed by the Cuyahoga County Planning Commission from a digital elevation model provided by the Ohio Statewide Imagery Program, 2006.

Additional Data Tools
Add layers from a layer catalog
Upload layers from your device
Add layers from a map service
Layer Catalog: The Layer Catalog is a place to hold other layers that may be of interest (without cluttering up the layer list for most users). Currently, only the local Soils Classifications layer is available. Soil types are somewhat randomly color-coded. They can be selected with query tools, but not filtered.
Upload Data: Local data from your computer can be temporarily uploaded into the map viewer. Note that uploading a single shapefile will only provide the graphic elements, and no attributes. If you upload a zipped set of files associated with shapefile set, then attributes will be brought along. Uploaded data cannot be used with Filter and Query tools. Data with unknown map projects may not appear.
Add Layers: Users can search for external map layers from ArcGIS Online using a keyword, or can enter a complete URL if known.
- Use the Add Layers button
- Search for: Redlining Cuyahoga
- "ArcGIS Online (3)" should appear in the panel
- Click the right arrow next to it
- Pick the + next to the top one from the list of three layers
The new layer will be at the top of the layer stack. It can be made semi-transparent with the slider.
Q1. Nothing happened when I made a selection or clicked on a link in the viewer. What happened?
A. In order to use certain features, including links to the County's Property Database MyPlace and making a printable map, you must enable pop-up windows for the viewer in your browser. Since each browser functions a bit differently, please consult your browser's documentation for instructions on enabling pop-ups (Chrome, Firefox, Edge, Safari).
Q2. Why can't I see the layer(s) that I have turned on?
A. There are several reasons. The most common cause is because you are zoomed out too far (or zoomed in too close). Several layers, like parcels, will not show up until you zoom in to a reasonable scale. Another reason may be that the layer's parent group is turned off. For instance, the Municipalities layer will not show if the POLITICAL group is turned off.
Q3. The colors on the map don't match the colors in the legend. Why?
A. Many of the layers are semi-transparent (e.g., Open Space by Type or Watersheds), so you may be seeing a combination of one color from a lower layer viewed through another color of a semi-transparent higher layer. Try turning off layers that may be conflicting with the one in question. Also, there is a transparency slider control to the right of some layers. Try moving the slider to the right (less transparent) or to the left (more transparent).
Q4. I've selected a feature with one of the query tools, and it's highlighted in yellow. How do I unselect it in order to remove the highlighting?
A. Click the left-facing arrow in the side panel to the left of the Identify Results, or click the query tool where there are no features to make a new selection, such as in the road right-of-way.
Q5. How can I get current Fiscal Office data for a given parcel?
A. When clicking on a parcel with the Identify tool (or other tools), you may see: "For more information regarding this parcel, please visit MyPlace." Click the hyperlink for MyPlace, and a new browser tab will open up for the Fiscal Office MyPlace page for that parcel. Each subsequent selection of a MyPlace hyperlink will open an additional browser tab. If you are interested in exploring a specific area, it may be worthwhile to continue in one MyPlace tab, rather than having the Greenprint Viewer generate multiple tabs.
Q6. Can I copy my query results to a spreadsheet?
A. Yes. You can do this for all query results from the Identify Results panel, or for a certain group of results by expanding that results group (right arrow next to group name). Then, use the context sensitive menu button (top right of panel ). From here you have two options. The most direct is to select "Export to XLXS or CSV. These will take all the data and export it to a new spreadsheet. An alternative is to and select "Switch to Table. From the table view at the bottom of the page, pick the layer's results that you are interested in from the tabs. Then select the text in the table, using either your left mouse button or shift+right arrow keys to select the text. Copy the selection and paste to Excel or other spreadsheet application.
Q7. When printing a map, what "Map Scale" should I pick?
A. Since your screen layout will not likely match exactly with the paper size chosen for your output, you will have to decide if it's more important to preserve the map scale as-is (current scale) or whether the outer extent of the map is more important (current extent). There are other preset scale options as well, which are all expressed in a "proportional scale", For example: 1:1,000 = 1 inch to 1,000 inches.
Below are some standard scales:
The printer-friendly map will have a graphic scale bar in the lower left corner and proportionate scale text in the lower right corner. Note that the scale text will be incorrect if the print is enlarged or reduced in any way.
Q8. Can I use the viewer on my smartphone or tablet?
A. Yes. The application can be viewed through any HTML5 compatible browser, and uses responsive design, whereby the map and its controls will be adjusted for a smaller mobile or tablet screen layout. Not all application features are available on all devices. While all the layers will be available, typically the handheld version of the viewer will have fewer tools available. Also, the cross-hair button in the upper left of the map will provide geolocation options that can employ your device's GPS.
Q9. How do I get back to the view I was looking at before?
A. Click the tool icon at the top right to bring up the tool tabs, and select the Navigation tab. Click the button labeled "Previous Extent". You may also use the context sensitive menu button
Q10. Can I use Greenprint layers in my own mapping application?
A. Yes. Most layers are available for download from the Cuyahoga County Enterprise GIS Department. Various web map services are also available. See the County's Open Data page. For more information, please visit https://gis.cuyahogacounty.us.
Q11. Can I save my query results for use at a later time?
A. Saved results are only available in the current browser session. Refreshing the page or navigating away will clear all saved results.
