ROCKVILLE MAPS

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.

System Requirements
These map applications require the Adobe Flash 10 or higher browser plug-in. If you do not have the plug-in, you will be prompted to install it. Please be aware that a number of smartphones and tablets do not support Adobe Flash. The supported web browsers and their miniumum versions are Firefox 3.5, Google Chrome 4, Microsoft Internet Explorer 7.0, and Apple Safari 3.

Highlights of the Map Applications

  • The design of the maps combines the latest web mapping software foundation from ESRI along with the rich Internet application technology of Adobe Flash.
  • Different sources of map data are combined into a single map (e.g., Rockville, Montgomery County, ESRI).
  • Most maps have base maps and aerial photos which cover the entire world.  Maps of the Rockville area can be viewed in the context of Montgomery County, the DC area, and beyond.
  • There is a Search function to find streets by name or other features depending upon the map application.
  • Bookmarks are included to quickly return to a map location. Users can add and save their own bookmarks.
  • Overlays are used to highlight and locate places of interest (Rockville Neighborhoods, Historic Districts, Parks, City Facilities, and Schools). Where available, places of interest will include links to web pages for more information.
  • Mark-up tools are convenient for drawing on the map with text labels and shapes to highlight map points and areas. Mark-ups can be saved for re-use and shared with other users.
  • The printing function produces formatted maps with title areas and also provides a preview image prior to printing.

This dynamic gallery consolidates access to many of Rockville's maps and mapping applications in one convenient place.  Included are the fully-featured map applications seen below along with a number of topic-specific maps designed for quickly finding information at a location.  After selecting a topic-specific map, such as Historic Districts, click the About button to the top right of the map to learn more about using the map.  Refer to the Legend for visual definitions of how the information is depicted on the map. Clicking on a shape or marker in the map will highlight it and open a pop-up with information at the clicked location.

General Purpose GIS Map

General Purpose City Map
Search Addresses, Find City Services and Property Information
This interactive map 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, City facilities and other points of interest can also be located in the map, many with links to descriptive web pages.
 
   

SWM Utility Fee 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 Easement Map 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 Map 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).
Example of Data Layers in GISWhat 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.
