Feb 5, 2020 at 23:51 comment added mdsumner ah yes, sorry I see my mistake now
Feb 5, 2020 at 20:50 comment added aborruso @mdsummer it should be the right control points coordinates
Feb 5, 2020 at 20:20 comment added mdsumner I think your control points are wrong, to me 532,2433 is at 407000,569000 - but the line should be counted from the top yeah? As in "-gcp 532 454 407000 569000"

Feb 5, 2020 at 17:31 comment added mkennedy What coordinate reference system is the other data using? Maybe include a Roma 1940/Monte Mario transformation into the definition. See EPSG::1660 at EPSG Registry.

Feb 5, 2020 at 13:16 comment added Ian Turton I'm not sure LCC is the same as LC Orthomorphic - do you have a date for the map?
