Geographic Information Systems (GIS) - Data
Data – The GIS data which is developed and used by the people.
The California Atlas (Cal-Atlas) is the centerpiece of GIS Data Discovery, Downloading, Sharing and Viewing in the State. We encourage all groups (local, regional, state and federal) producing and consuming GIS data in the state to:
- Register as a Cal-Atlas User - http://projects.atlas.ca.gov/account/register.php
- Check the Atlas for existing data before re-creating the wheel - http://www.atlas.ca.gov/discover.html
- Register your data with Cal-Atlas to ensure everyone knows about the data you own, steward and add value to California for - http://www.atlas.ca.gov/contribute.html
The California GIS Council has endorsed a data plan for the GIS data needs of the state (see http://cgia.org/geospatial-draftplan.htm). The primary focus for GIS data are the seven ‘framework’ layers. Our goal is to have these seamless layers coordinated and available for use:
| Data Theme | Working Group | Strategic Plan | Standard | Business Plan | Data |
| Parcels | |||||
| Imagery | |||||
| Transportation | |||||
| Elevation | |||||
| Hydrography | |||||
| Geodetic Control | |||||
| Government Units |
In addition, the California GIS Council has also identified these 11 layers as being significantly important to meet state policy issues:
| Data Theme | Working Group | Strategic Plan | Standard | Business Plan | Data |
| Street Addressing | |||||
| Utilities | |||||
| Public Land Conveyance | |||||
| Buildings and Facilities | |||||
| Flood Hazards | |||||
| Vegetation | |||||
| Biological Resources | |||||
| Cultural and Demographic Statistics | |||||
| Soils | |||||
| Wetlands | |||||
| Earth Cover |
