Hi all
I would like to create ERDAS Imagine compliant overview files for a
larger satellite archive (mainly GeoTIFF files) in an automated way. The
"gdaladdo" tool has the possibility of defining this with "--config
USE_RRD YES". But this writes out not the typical ERDAS *.rrd files but
adds the overviews into an *.aux file instead. This is not recognized
properly by Erdas or ArcGIS. Just renaming the *.aux file to *.rrd does
not fully work since Erdas complains and spits out some error messages
(it opens the files after that, though).
Are there any plans to implement the plain *.rrd output and leave the
*.aux file for the typical usage of Erdas/ArcGIS for storing other
parameters like histograms etc? I guess the format change between the
plain *.rrd and the *.aux is very low, proably the aux file adds some
additional header lines or something like that.
Best regards
Armin
