ROCKVILLE GIS DATA
GIS data from the City of Rockville is available for download and use in mapping applications such as ArcGIS Desktop, ArcGIS Explorer Desktop, or Google Earth. With these data, users can compose their own maps and perform data analysis.
The GIS web mapping applications below offer many features and functions for finding geographically associated information and for producing maps. For assistance with using the maps, follow the Help link in the upper right corner of the map. Note that the help pages for the special purpose maps each include a Get Right to It! page for concise instructions on how to get right to using the map for its purpose. Also see the set of video tutorials (Adobe Flash format) which have been produced to demonstrate map use.

General Purpose City Map
| Stormwater Management Utility Fee Estimate|
City of Rockville property owners can view their property on an aerial photo map that shows the measured impervious area and generates an estimate of the annual Stormwater Management Utility Fee. The measured impervious area is colored light brown on the map. Owners may access the map here. This map will be updated as information changes. To view a property, click on the ‘Find an Address’ tool in the top of the screen and type in the address. Alternately, use the navigation toolset on the left side of the screen to navigate to your property. Use the ‘hand’ tool to move around in the view to your vicinity and zoom in on the property with the zoom slider. Once you find your parcel, click on the ‘i’ (identify) tool, then click on the desired parcel.
| Forest Conservation Easements|
This map shows the existing forest conservation easements within the City of Rockville and provides supplemental data such as the approved Forest Conservation Plan number, Montgomery County Land Records reference number (if available), size and type of easement, and notes on forest conservation credits. There are two types of forest conservation easements: one that protects forests and one that protects individual trees. Easements protecting forests are placed over the forested areas only within the property boundary and are labeled as “partial”. Easements protecting individual trees are usually placed over the entire property and refer back to the approved Forest Conservation Plan to show which trees are covered by the easement. These easements are labeled as “entire.” Street trees are protected under the Maryland Roadside Tree Law and therefore, not subject to forest conservation easements. If you have questions on forest conservation easements, please contact the City Forester’s office at 240-314-8700.
| Urban Tree Canopy|
City of Rockville property owners can view their property on a map that shows the estimated percentage of their property that is covered by tree canopy. Properties are color coded based upon the percentage range of tree canopy their property falls into. This map shows tree canopy data taken from 2007 aerial imagery. The analysis was performed by the University of Vermont’s Spatial Analysis Laboratory in consultation with the USDA Forest Service's Northern Research Station. For more information, view the Urban Tree Canopy Report (pdf).
|What is a GIS?|
A geographic information system (GIS) is a computer-based tool that combines the visual appeal of conventional maps with database operations and statistical analysis. It is used for mapping and analyzing things that exist and happen on the surface of the Earth by classifying the information into "layers", making it easy for users to distinguish each element separately. The speed and accuracy of a GIS provide an invaluable service to organizations, such as the City of Rockville, by explaining events, predicting outcomes and planning future strategies.
