Thanks again for your advices. Unfortunately, I get the same image with shp2img : shp2img -m mapfile.map -o /tmp/foo -e -179.99 -89.99 179.99 89.99 -s 800 400 -l polar_orbiting_avhrr4 -i image/png -all_debug Nothing special in the debug massages.
No change about the projection error message with a corrected projection string or with projection auto. I activate the epsg:4326 (though this is not exactly the projection of my data) definition to actually have a projection defined into the layer without any error message. 2015-08-12 17:28 GMT+00:00 Jeff McKenna <[email protected]>: > On 2015-08-12 11:43 AM, fred p wrote: > >> Thanks to Jeff for the answer. >> >> I simplified the mapfile to make it easier to read. >> >> Below I give the mapfile with these additional elements.
