Open Space in California

This map describes counties in California and the percentage in acres of total public open space based on the managing agency/owner:

Federal
State
County
Land Trust

The data are derived from the California Protected Areas Database. Which contains GIS data about lands that are owned in fee and protected for open space purposes by over 1,000 public agencies or non-profit organizations. The data as mapped here were manipulated in several ways to produce a reasonable choropleth map. Summary statistics were run in QGIS to determine the managing agency type that held the most acreage in four separate classes. Those data were then brought intoe excel and a pivot table was made so that each managing agency had its own field with the total acres by county. That data was then joined to a cartographic boundary file of California counties and converted to a GeoJson for use in this map.
