geographic information systems (gis)

More information on GIS systems is being developed that will be useful to existing clients of SkyTruth and potential partners in need of substantial GIS solutions. For now we have provided information to get you started in exploring existing resources.

Government agencies at many levels are active users and providers of GIS-compatible spatial data, and occasionally pursue projects of interest to environmental NGOs (studies of urban sprawl, loss of agricultural or forested lands, and non-point source pollution, for example) at the municipal and State level.

Some states, such as California, have well-staffed GIS groups that routinely use remote sensing data for such projects. Many states are establishing spatial data clearinghouses to make GIS data, aerial photographs, and even satellite imagery available to the public. Even at the county level GIS use has, in more and more localities (for example, Fairfax County, Virginia), become sophisticated and routine.
