SRAP’s GIS Portal was created to help communities understand the damaging impacts of industrial livestock production by providing insight into geographic characteristics, demographic trends, and patterns of pollution. The Portal compiles publicly available data and map layers from government, academic, and other sources to provide a one-stop mapping resource for advocates and communities facing industrial livestock operations.
The Portal includes national GIS layers along with state-specific GIS layers for the states listed below.
See our layer description page for more information about each layer.
How to Use the Portal
Switching From National to State View
The Portal includes national data layers, and additional state-specific layers for several states.
- To access state-specific layers, click the state name on the right side of the map.
- To return to the national-level view, click “Back to U.S. Map” on the right side of the map.
*Note: in national view, state-specific layers are not visible, even if you zoom in on the state; switch to state view to find additional layers.
