I need to merge multiple kml files into a single one.
I found that I could use “ogr2ogr -append” but I have to do it through c++ and my Google-fu hasn’t been successful so far.
So, any ideas?
Also, how to add new fields(and manually values in that field) in a kml file (through C++ again). Probably something to do with OGR_Fld_Create?
