Compiled Ground Failure Data from the California Geological Survey

KMZ and GeoJSON files with data collected by CGS.

 

CGS is currently using Collector for ArcGIS on behalf of the Clearinghouse to acquire data on surface fault rupture, landslides, and liquefaction. Data are being downloaded from ArcGIS Online (AGOL), by python script, every hour and being converted to KMZs and GeoJSONs. These files, along with a geodatabase, is being zipped, timestamped, and place on http://gmw.conservation.ca.gov/CGS_Emergency_Responses/ for you to download and use as needed. 

Please note, there may be times when you download a new zip file and the KMZs and GeoJSONs have not been updated. Many of the geologists are using Collector in the offline mode. This means data will not be synced to AGOL until they do it manually when back from the field. These data, however, will be available within an hour of the time they manually sync to AGOL.

Also, this is the first time we are using Collector and the download script and have been troubleshooting the script over the past couple of days. We believe the script is now working, however, we are monitoring it closely and will fix it as quickly as possible if it encounters issues.

Please feel free to contact Kate Thomas at Kate.Thomas@conservation.ca.gov if you have any questions.
