The NJTPA makes extensive use of Geographic Information Systems (GIS) computer mapping systems that can spatially manage, analyze and present geographic data. Much of the data that inform transportation decisions describe physical locations in the region and are maintained in a GIS. Examples include framework transportation layers (road network, rail lines, ports, bus routes, airports), land use data, aerial photography, and other planning layers (e.g., NJ Office of Smart Growth centers and planning areas). NJTPA also collects and maintains GIS layers that reflect various environmental features, such as wetlands, parks, and historic areas. These GIS layers are used, via overlay analyses, for the purposes of assessing potential project impacts as part of the development of plans, programs, and various planning studies at the NJTPA.
