Geographic Information Systems (GIS) include computer-based systems which capture, store, retrieve, analyze and display 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, linking maps and databases to form a relationship between data, locations, and information.
The City of Lowell's GIS maintains a large amount of data in "layers" which can be overlaid onto City maps.
These layers include building footprint locations, address information, the street centerline network, railroads, waterway and 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 suite of tools, and presented using Applied Geographics' General Purpose Viewer (GPV).
