I'm looking for a way to get the intersection area between my shapefiles. Basically, I got three shapefiles from my .tif files like this:
gdaltindex a.shp a.tif gdaltindex b.shp b.tif gdaltindex c.shp c.tif
This way I got the area of my .tif files.
Now I would like to get a new shapefile via intersection.
I thought about using
gdalwarp, for example like this:
gdalwarp -cutline intersection.shp a.tif a_intersection.tif gdalwarp -cutline intersection.shp b.tif b_intersection.tif gdalwarp -cutline intersection.shp c.tif c_intersection.tif
but i can't figure out how to get the intersection.shp file I can do it via QGIS, but would like to do it directly from GDAL. How can I do this?
