Geographic Information Systems is a computer-based system for capture, storage, retrieval, analysis and display of locationally defined (spatial) data. GIS applies modern computer graphics and database technology to the efficient, cost effective management and planning of the city's assets. GIS links maps and databases to form a relationship between location and information.                                                   

The City of Lowell Geographic Information System (GIS) maintains a large amount of data in "layers" which can be overlayed onto City maps, which we hope you will find helpful. These layers include building footprint locations, address information, street centerline network, railroads, waterway/wetlands areas, paved roadways, schools, neighborhood boundaries, election wards and districts, zoning boundaries, police and fire stations, and a digital parcel base map that displays the information taken from the hard copy Tax Assessor maps. The maps are rendered through ESRI's ArcGIS and ArcIMS tool suites.
