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

Hi,
i am a very beginner in GeoTiff and Georeferencing.
_ i have an image in .emf file format.
_ i also have these UTM informations:
Easting,Northing,Zone,Hemisphere
Exemple: 400000,4379520,24,N
How can i use GDAL to create a geotiff from these informations ?
(My GeoTiff need to be in wgs84, epsg:4326)
(i need to use command line tools, no GUI)
i think i need to convert .emf to a file format which can be supported
by GDAL such as .bmp ou "standard" .tif. But After ?
Maybe with gdal_translate and/or gdalwarp, but how ?
Note: i am a very beginner.
Regards
