	Title	ALRIS
	Description	The Arizona Land Resource Information System, or ALRIS, was started in 1982 and has since been managed by the Administration and Resource Analysis Division of the Arizona Sate Land Department. The ALRIS program provides support services for Arizona's Geographic Information Systems (GIS) community by offering "training and consultation in the use of the system, related technical services, and limited production services to system users." ALRIS is a clearinghouse for Arizona spatial GIS data, and therefore a wide variety of GIS data is available through this site.
