How Local Governments Provide GIS Services via the Web

"By making these GIS-based services available to the community via the Web, city and county governments are providing a powerful resource to the public"

Exploring the Synergy between GIS and Web Services, a publication released this week by the Public Technology Institute (PTI), looks at the many different geospatial information systems (GIS) applications that local governments are providing via their Web sites.

As a tool to enhance economic development, some local governments are creating Web applications that allow businesses and private citizens to examine, online, facilities or sites ready for development. A wide variety of data on demographics, land-use controls, and transportation/access restrictions can be provided. GIS data provided, via the Web, becomes the "face" of economic development presented to outsiders. Parcel maps and online property data can be used to streamline property transactions.

Citizens also provide information to government: citizen use of a government Web site for a business transaction often involves providing a mailing or billing address. A GIS geocoding engine can ensure that the address information that is entered is valid, and also provide information about service districts, election districts, ZIP code, and any other boundaries of interest.

When dealing with emergency management and response, online maps have proven to be very effective in keeping citizens informed about large-scale disasters, such as wildfires and floods, and directing individuals living in specific areas to take appropriate action. Online maps of street closings and transportation infrastructure construction can alert citizens to what is happening in their neighborhood and what might affect their morning and evening commutes.

"With this publication, PTI hopes to show local officials how, by taking advantage of their investment in GIS technology and applications, and by making these GIS-based services available to the community via the Web, city and county governments are providing a powerful resource to the public," said PTI Executive Director Alan Shark when releasing the publication.
