Does anyone know where I could get free GPS data on certain types of locations for any country

Question

I am currently building a web application server which essential would allow a client application to send it's current location and query on the server for the closet locations of a certain location type, examples of location types would be nearest payphone, nearest restaurant or nearest gas station.

Does anyone know where I could get the GPS data for free? I would eventually like to have data for pretty much any country in the world.

It would be preferred that the GPS location data to be in decimal format, I am flexible with the file format containing the data.

Answer 1

check out this site. it provides access to data for GPS markers, etc as a service or if you prefer, you can download its entire database. hope this helps!

OpenStreetMap may contain the location types you're looking for, and if they don't you could always convince the community to start mapping them.

LinkedGeoData also contains geospatial information (based on OpenStreetMap, but with the potential for linking to other datasets), and may provide a way to extract the information you're looking for, although this is something I've only recently come across, so can't say one way or another; I mention it in case it proves useful to you.

Hope that helps
