Hey Even - me again on this xyz sorting issue. I've got a new xyz file that it is not recognised by gdal even after using the sort command you provided earlier in the thread.
The problem xyz is here | https://dl.dropboxusercontent.com/u/4086367/001-1.xyz.zip The error is: ERROR 1: Ungridded dataset: At line 363, X is 568509.090000, where as 568514.090000 was expected (1) gdalinfo failed - unable to open '001-1.xyz'. GDAL seems to fail at the start of a new row of data? I've tried various descend/ascend combinations of the columns = no joy. I'm running GDAL 1.11.0 on OSX 10.9.3. Any ideas? Thanks again in advance for any help! Very much appreciated. Cheers Sam On 27 May 2014 14:09, Sam Franklin <[email protected]> wrote: > Hi Even.
