Geographical Information System (GIS) mapping uses spatial (geographical) data to create information-rich maps that benefit understanding, analysis, and decision-making. A GIS system allows multiple categories of data to be selected for representation on a map.
GIS mapping is useful for the Division of Oil, Gas, and Geothermal Resources (DOGGR), industry operators, the public, and other users in various ways. For example, GIS aids in planning for spill management by mapping the locations of wells and associated facilities, other structures, and natural resources.
DOGGR also hosts several interactive maps to allow easy viewing and querying of its GIS data.
GIS mapping helps DOGGR in its mission of ensuring public safety and environmental protection as it oversees California’s oil, gas, and geothermal production.
Well Finder: An Interactive map viewer that includes location of wells, fields, seeps, and notices and permits in California.
CalStim 'D: An interactive map viewer that includes locations of well stimulations and permits in California.
