I'm looking to map "State Parks," and I found this phenomenal, but complex database. Has anyone ever worked with the PAD datasets before? (or know any easier way to map State Parks?)
In the PAD download there are several included shapefiles, including:
designation. It sounds like there is overlap in the datasets. So far my best guess is to use the
fee shapefile, filtering on
access='open access' and
designation='state historic or cultural areas' or 'state park' or 'state recreation area'. But I'm just not 100% sure if I've gotten everything this way. The total number of features returned is 8,065, which is close to the number noted at stateparks.org (8,565 for FY 2017), but it's still 500 features short. When I add in
designation='state other or unknown' it brings the total up to 8,447. Although I suppose this number could have (and likely did) go down since the latest release of the data. Still, it would be nice to know the exact query I should be using.

I'm aware of all the following helpful documentation already:
Data Structure and Attributes
“Any use of PAD-US data for showing recreational lands must be careful to show only those lands that have fee ownership and designations that are appropriate to recreational use – the PAD-US ‘Access’ attribute is a key tool for these applications, defining what is Open, Restricted/Permitted, and Closed for public access.”
