Downloadable GIS Shapefiles

Back to Locations of Groundwater Protection Areas

These files contain the spatial data required to plot the townships and sections for each California county or for all of California (Statewide). These files are based on the Bureau of Land Management Public Land System data for California but have been enhanced with additional linework to extend the township and section data across the numerous land grant and unsurveyed areas of the State. These added sections are valid only in relation to pesticide use reporting and well location.

A Geographic Information System (GIS) program is required to view these files. Each county folder contains two shapefiles (each shapefile consists of a set of seven files). One shapefile set contains the data for the townships (mtr_XX_nad83) and one shapefile set contains the data for the sections (pls_XX_nad83) where the XX is the county number. Both shapefiles are in the Albers Equal Area (NAD 83) projection – also referred to as the NAD 1983 California (Teale) Albers projection.

Each of the county folders also has a county.kmz file. This file also shows the sections and can be imported into programs such as Google Earth®. There is no statewide.kmz file as it would be too large for Google Earth® to accept.
