Mapping Municipal Discrimination

GIS maps are being used to identify where communities need services -- and whether some communities are victims of municipal discrimination.

"The Cedar Grove Institute has been using maps to exhibit patterns of municipal discrimination against low-income and minority communities for almost a decade. The patterns, rooted in the days when residential discrimination was supported by law, have been reinforced under the cover of such contemporary land-use mechanisms as annexation, zoning and extra-territorial controls.

To produce the maps, the institute employs geographic information systems technology, a computer-based tool for organizing, analyzing and displaying data in a spatial or geographic context. While the maps seem simple, producing them is anything but. Data must be collected from a host of sources, including government databases, door-to-door surveys and Global Positioning System devices. The data is digitized, analyzed, converted to images and layered together in various combinations."
