[Gdal-dev] Gdal_translate and the Internal accuracy of ground control points

[Rahkonen Jukka]

Hi,
 
I have inserted ground control points into a GeoTIFF image file with gdal_translate in this way:
gdal_translate input.tif  output_gcp.tif -gcp 0 0  285113.632 6713217.584 etc.
 
Gdalinfo reports me about the resulting image as follows:
GCP Projection =

GCP[  0]: Id=1, Info=

          (0,0) -> (285114,6.71322e+006,0)

 

Are the gcp's still stored into the GeoTIFF file with the same accuracy I gave them, or are they rounded like gdalinfo is expressing them?

 

Regards,
