Hi list,
I've got a tiff file of 28 Mb and it is really slow, so I am assuming the
classification gets applied on the fly or something like that.
If I do a gdalinfo I get a huge list of STATISTICS_HISTOBINVALUES
Metadata:
STATISTICS_MINIMUM=-5838
STATISTICS_MAXIMUM=4225
STATISTICS_MEAN=-1010.4585191036
STATISTICS_MEDIAN=-212
STATISTICS_MODE=1
STATISTICS_STDDEV=1833.0113850333
LAYER_TYPE=athematic
STATISTICS_HISTOBINVALUES=1|1|1|1|1|1|1|1|1|1|1|2|1|2|1|1|1|2|1|1|1|1.......
Also, the GDALRasterAttributeTable has 9150 rows. Don't know if this is
related.
Any ideas on how to speed this up? I tried to write it out to a new
GeoTiff or MrSID file, but somehow all this info is preserved, and the
slowness continues.
TIA.
Best regards,
Bart
