[gdal-dev] geojson to shp and vice versa

[Kristijan Cindrić]

Thanks for the prompt answers! Ok, it's clear now on what's the problem
here.
Is there a way I can iterate through a .zip file containing individual .shp
files, each file with its own geometry type (point, line, polygon), using
ogre.adc4gis.com API? I could then append each feature to a geojson feature
class and show it to the user. If ogre.adc4gis.com doesn't work I can try
to run ogr2ogr in my app so suggestions in that way are helpful also.

Thanks,

Chris
