What is "GIS"?
GIS stands for Geographic Information System. It is a means of displaying and analyzing data that can be referenced geographically. GIS can take data that has been traditionally stored in tables, give it geographic references, which can then be displayed graphically on a map.
How does the Washington County government use the GIS mapping?
The GIS mapping database is relied upon heavily by the County government. Generally speaking, all official "spatial" or map-related data and records of Washington County government, including the mapping of all land parcels of record and the official Zoning Map of Washington County are part of the GIS mapping database. By making this mapping system available to the public, the Washington County government is permitting the public access to the same information County elected and appointed officials and employees use to make important decisions on a day-to-day basis.
How can GIS help me?
By making Washington County's maps and data accessible on-line, GIS helps make the County government more efficient. It allows for convenient access to a large amount of information that before would have required considerably more time to acquire. Through interdepartmental information sharing and communication, productivity is enhanced and everyone benefits. Washington County's GIS site offers the user a wealth of data such as zoning information, parcel information, and addressed structure information. You can even view an aerial photo of the County! A variety of tools such as pan, zoom, search and print allow the user to perform many tasks and help make the site very functional.

The County Department of Information Systems is officed in the Public Safety Building, 20281 Rustic Lane, Abingdon, Virginia.
What are your hours of operation?

How current is your data?
We strive to keep each layer as up to date as possible. Almost every layer is updated as soon as we receive an update or correction from the appropriate agency. Presently it takes about 30 days from the date a new parcel of land is created through recordation of a plat with the County Clerk of Circuit Court until the new parcel is mapped on the GIS.
