Rockville City Maps and GIS
General Purpose City Map
Search Addresses, Find City Services and Property Information
This interactive map, developed by the Department of Information and Technology, provides a convenient way to search addresses for location and to view information for City services and property ownership. City-related information associated with properties includes water service source, recycling & refuse service, voting location, neighborhood coordinator contacts, code inspection contacts, zoning, and more. In addition, each property includes State of Maryland property parcel data for tax assessment information. Schools, parks and City facilities are also shown in the map, many with links to descriptive web pages.
Project Development Status
The Project Development Status map has been temporarily removed from the site for maintenance. Visit Development Projects in Rockville or contact the Community Planning and Development Services Department at 240-314-8200 for more information.
For a list of development applications filed in the Planning and Zoning Division this month visit the Permits and Applications page.
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 FY 2010 (calendar year 2009) Stormwater Management Utility Fee. The measured impervious area is colored light brown on the map. Owners may access the map here. This map shows impervious area taken from 2006 aerial photos and is based on the current projected SWM Utility Fee rate of $61.85. This map will be updated as information changes.
To view a property, click on the ‘Locate Address’ box on the right side of the screen and type in the address. Alternately, use the toolbar 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 ‘+’ tool. Once you find your parcel, click on the ‘i’ (identify) tool, then click on the desired parcel.
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.
What's a GIS layer?
A layer is a collection of specific elements, such as trees, roads, buildings that can be viewed together with other layers for a complete overview of the area, or separately to give a more specific indication of the presence of that particular element. GIS stores information about the world as a collection of layers that are linked together by geography. As these layers combine with each other, a picture of the real world emerges. This simple but extremely versatile concept is invaluable for solving many real-world problems such as the tracking navigation, managing governmental services, as well as modeling global atmospheric circulation.
