im in the middle of planning a mobile game with GPS support, for that matter i need to know on what type of terrain/areal someone is currently standing.
The information i need, doesnt need to be too detailed, i want to know: is the player currently inside of a city/town/village (are there streets and houses near or not), is the coordinate on a street, a lawn/grassland (nice would be to know if its “wild” grassland or domestic, like a park or a private garden, but not mandatory), a forest/wood or water.
So basically just what a human gets by looking at the map
sorry if this was asked before, i couldnt find anything that really matches my problem but its likely that i used the wrong search phrases, in that case i would be happy if someone could just point me in the wright direction
Do you need information about how implement such features (eg how to work with geometry, GIS libraries and other coding stuff) or just a description of related tags (to look for in OSM data)?
good question! i think something of both…
i know openstreetmap has the data that i want to get but i dont know how to get it.
The game currently can get the gps coordinates of the player and i know how to display this point on a map but what i like to to with the coordinates is to ask some api “what can you tell me about this position”, what i want to get as an answer would be at least “hes standing on a street/lawn/forest in city x or near city x (if outside of town)”, hope this makes more sense
what would also work is “tell me the color of the map at this position” but i guess the color of the map is chosen by the type of terrain
There is an API, check out Overpasshttp://wiki.openstreetmap.org/wiki/Overpass_API.
It’s probably able to get you near features or within features based on a location. You would still have to build something that uses that information te classify what kind of place that data would be.
Thank you! will check it out!
