Hi, I'm trying to wrap my head around Geotiff's AREA_OR_POINT=Area versus AREA_OR_POINT=Point, and how that translates into GDAL. I've read the "PixelIsPoint Raster Space" and "PixelIsArea Raster Space" sections of the geotiff spec, and tried to find previous posts on the topic with very limited success ( http://osgeo-org.1803224.n2.nabble.com/GRASS-Problem-importing-geotiff-with-r-in-gdal-td1879130.html ). Am I correct in interpreting this post to mean that the pixel-is-area and pixel-is-point tiffs are read the exact same way by GDAL, with the only difference being in the value of the AREA_OR_POINT metadata key? Should viewers then be looking for the "AREA_OR_POINT" key in addition to the georeferencing information, and shift the display to center the top-left pixel on (0,0) if it's set to Point?
