It looks like this: +init=epsg:4121 +proj=longlat +ellps=GRS80 +datum=GGRS87. gdalwarp assumes that you have provided an orthorectified image. 459880 ,38. Cadastre, engineering survey, topographic mapping (large scale). Setting projIn is harder, because your netCDF file defines its coordinate system with a WKT string, which (I'm pretty sure) can't be read directly by proj4 or pyproj. 970769, 37. Only on top of the Equator one degree is as long in both directions. 1. EPSG:5270 Projected coordinate system for Türkiye (Turkey) - between 28°30'E and 31°30'E, onshore. I am quite a bit confused for example if, at least in practice, EPSG:4326 is equivalent to Plate Carrée equirectangular projection. The UTM32N one has square pixels in UTM32N, measured in meters (60x60m), and each pixel has the same area. See CRS code 5678 for variant with axes order reversed to easting before. You can do this using the EarthExplorer portal. Specifically, a square of 0. Projected bounds: -20,026,376. Transforms using the pipeline= argument may fail if there is ambiguity in the axis order of the specified coordinate reference system; if you need the traditional GIS order, use "OGC:CRS84", not "EPSG:4326". EPSG:4326 and IGNF:WGS84G It looks like both of them do not fit because of the map distorted in both cases. 8589506) Lon(2. 3 364110 4110007 (corner) M1.
