Do you know of any sites that I could find some recreational shapefiles?
An example would be shapefiles of golf courses, ski resorts, or maybe baseball fields in the United States?
I would suggest checking the other other questions that have the POI tag for a more comprehensive list, but a couple that come to mind right away are:
U.S. GDT Large Area Landmarks Shapefile 1:100,000 2000 landmarks, military installations, reservations, penitentiaries, prisons, educational institutions, amusement parks, government centers, sports centers, sports complexes, golf courses, cemeteries, cemetery U.S. GDT Recreation Areas Shapefile 1:100,000 2002 recreation, golf courses, zoos, resorts, recreational facilities, society, beach resorts, golf clubs, hotels, country clubs, casinos, museums, gardens, historical sites, amusement parks, science museums, historical museums, parks, culture U.S. GDT Recreation Areas Shapefile 1:100,000 2000 recreation, golf courses, zoos, resorts, recreational facilities U.S. GDT Recreation Areas Shapefile 1:100,000 2002 point, recreation, golf courses, zoos, resorts, recreational facilities, society U.S. GDT Recreation Areas SDC (Smart Data Compression) 1:100,000 2002 point, recreation, golf courses, zoos, resorts, recreational facilities, society.
But Open Street Map is likely to be more up-to-date.
If your in the UK, the Ordnance Survey has a vast collection of data now available in public domain.
The "OS Vector-map Product" has lot's of things in from amenities to leisure centres, churches and a whole raft of other things.
There's many other map products too such as "Strategi Map" that include usefull data sets, all is available to download as Shapefiles, and they'll even send you the larger ones out on DVD's free if you request it.
