I apologize for the cross-posting but there are relevant conversations now on both OSM-talk and geowanking regarding this data. I just took a quick look at a dozen or so different parks comparing the federal lands data I linked earlier with the data Andrew Turner just posted. Unsuprisingly the NPS data is of higher resolution at each of the sites I checked out, and in a couple of cases the federal lands data has huge inaccuracies (though it mostly looks like problems with borders between federal lands). The federal lands data also lacks a projection (appears to be NAD 1983).
If you use the federal lands data, I also suggest you toss the NPS boundary data on there and use that where appropriate. -Tyler Ritchie On Wed, Jun 17, 2009 at 6:48 PM, Andrew Turner <[email protected]>wrote: > Here is a full catalog of NPS GIS data: > > http://science.nature.nps.gov/nrdata/index.cfm > > particularly: http://science.nature.nps.gov/nrdata/datastore.cfm?ID=47653 > > On Tue, Jun 16, 2009 at 7:58 PM, Andrew > Johnson<[email protected]> wrote: > > Hi everyone, > > > > Is there a public data source that contains boundary files for all the > U.S. > > National Parks and Forests?
