| Jan 8, 2018 at 20:15 | comment | added | johlund | Sorry Vince! So the path-column that the plugin Image Footprint creates in the footprint attribute table can be used by PostGIS to get me the answer without having to load a singel raster file into the db? Even though it's not solely a xy, but mainly a z-overlap I wanna determine? | |

| Jan 8, 2018 at 19:40 | comment | added | johlund | Thanks for the first explanation I've received on what a footprint is, very helpful! I removed the duplicate question about raster2pgsql. If I understand your definition of a footprint correctly, loading a footprint won't do it for me since I need all the z-values in every 2x2 meter cell of the 700 MB raster!? Looks like I'm gonna need an A380 to deliver the mail? | |

| Jan 8, 2018 at 17:57 | comment | added | Vince | You still have multiple questions here. A footprint is the quadrilateral polygon constructed from corner points e.g. { SWx, SWy, SEx, SEy, NEx, NEy, NWx, NWy, SWx, SWy}). Loading the rasters into the database solely for the purpose of determining overlap is like using an A380 to deliver mail in the bush. | |
