gdal utm .sid to lat/long .geotiff {Scanned}

[Siki Zoltan]

Hi,

A did something similar recently with a 50 MB sid file.
The mrsiddecode took appr. 10 hours, and i get 1 GB tiff.
Then I used gdalwarp to split the images, it was much faster.

An other solution to have gdal with mrsid support.
There were some threads on the list about it before. Check it.
You have to download an extra library from LizardTech.

Bye
Zoltan
