Rockville City Maps and GIS
Rockville's maps are a product of its Geographic Information System (GIS), a computer-based tool that combines hardware, software and data for storing, displaying and analyzing information which has a geographic, or locational, association. 

At its very core the City of Rockville is a geographic entity, defined by its land area and everything that goes on within its boundary. Many types of physical and virtual assets are associated with geographic locations within the City. Data maintained in Rockville's GIS include streets and property parcels; zoning and neighborhoods; water, sewer, and storm drain utilities; parks and city facilities; and scores of other datasets. 

Using a GIS for analysis can result in better decision making because it helps to answer questions and solve problems related to where things are, how dense or sparse they may be, what kinds of patterns or relationships may exist, what's nearby or within an area of interest, and how things have changed over time. And because GIS data can be visualized through maps, it can make complex information easier to understand.
