I have two shape files that i want merge (overlay/intersec) having in the destination the attributes of the the two sources file.
ogr2ogr file_merged.shp tl_2010_us_uac10_conus_albersUA.shp ogr2ogr -update -append file_merged.shp tabblock2010_10_pophu.shp -nln file_merged
In this way i obtain the polygons of the two shapes but i lose the attributes of the tabblock2010_10_pophu.shp.
My final aim is then make an sql statement where i can retrieve polygon in common in the both shapes.
Thanks in advance
