Jonathan, Check out the National Atlas. http://nationalatlas.gov
It has downloadable raw data in a mix of formats such as ESRI Shapefile (.shp),
ESRI ArcInfo Export (.e00), and the federal Spatial Data Transfer Standard (SDTS). The Atlas' boundaries section contains a layer of federal lands and a layer of Wilderness Peservation System Areas. There are also a number of other interesting layers that are useful for basemap, references or other comparisons. While this will provide good information on federal lands, for state and local parks, you may need to obtain data from each state and local agency. You can access the National Atlas raw data download page at: http://nationalatlas.gov/atlasftp.html There are also some data layers available for the North American Atlas at: http://nationalatlas.gov/atlasftp-na.html Hope that helps. -John John Donoghue School of Natural Resources University of Arizona donog...@email.arizona.edu Quoting Jonathan Greenberg <greenb...@ucdavis.edu>:
Ecologgers: Does anyone know if there is a GIS layer that contains coverages for all protected regions in North America (e.g. national, state and local parks, private and non-profit wildlife preserves, etc.)?
