How to use a downloaded map in monkey C

Apologies in advance I'm very new to monkey C.

I'd like to make myself an app based on map data I can download from a website. The site offers map formats in .dxf .gdb .shp .geojson .gdd .gml .kmz and .sos 

Id ideally like to have the app warn me when I walk into specific areas on the map. I was wondering which format would be best (if possible to use) with monkey C and if anyone could recommend any tutorials for making an app using said format. 

 Thanks a lot for any help :)
