GIS Resources

The Department of State Lands (DSL) offers a variety of GIS -Geographic Information System - services and products for the public. Three departmental employees provide assistance on data development and mapping for the land management, waterway leasing, wetlands, removal-fill permit, South Slough and other agency programs. 

DSL's GIS program uses the most current geospatial technology (ESRI, ArcGIS, ArcIMS, ArcGIS Server, ERDAS, Lizard Tech, Trimble GPS) to provide both desktop and online mapping resources for customers and staff.

In 2010, the agency led the development of a Web-based Statewide Land Inventory System for 20 state agencies with land holdings. The inventory is the first comprehensive mapping of state land ownership, and is currently a beta version.
