[gdal-dev] How to create GeoTiff from image and UTM Coordinates

[Adrien André]

Hi,

you need to know your data spatial resolution and the pixel coordinates 
corresponding to (Easting,Northing).

If GDAL cannot read the .emf file, try using ImageMagick:
convert image.emf my_raster.png

Then, you might try to create a worldfile my_raster.wld (See [0]).
The attached example is for a resolution of 10x10m and if 
(Easting,Northing) is for your image upper-left corner.

Then provide source SRS info and warp:
gdalwarp -s_srs EPSG:32624 -t_srs EPSG:4326 my_raster.png my_raster-geo-tif

Hope this helps,

regards
