In order to make our data easier to find, sometimes a nice table or spreadsheet is what you want. LA County has created a new page which lists all of the GIS Data Los Angeles County has identified in its systems, compiled and organized, with active links on this site to where the data can be downloaded. This should make it easier to find and access its data, and avoid some of the potential hassles of searching for data one by one.
The data catalog is located here: http://egis3.lacounty.gov/dataportal/data-catalog/
As well – if you have any feedback, don’t hesitate to provide that to them here: http://egis3.lacounty.gov/dataportal/feedback/
