Hello,
I am using osgeo.gdal python module to load and get stats from image
bands.
While working with the, python, 'GetStatistics(...)' function I noticed that
the returned values seemed a bit off.
A snippet of code is shown below.
I compared the statistics returned in python by the function t

Hello,
Sorry about the title but it's a bit of a bear finding answers if the
headers don't show the actual topic.
But I digress.
My Issue:
I have an input image that covers coordinates 0,0 to 450,350 UTM zone 13

I want to mosaic pixels 0,0 to 25,25 into a cov
Hello,
I have some input data where the dynamic range and offset of each channel

This means that applying the same linear enhancement based on data range to

Hello,
Good news.
Removing the '.aux.xml ' file and again running gdalinfo -statsindeed
fixes the problem.
I now get the expected statistics values.
Thank you for your help.
Best Regards,

Hello,
I am seeing that you are correct that the 'no data value' is being read in
each case.
Perhaps my interpretation of the problem appears incorrect.
Look, however at the 'Metadata:' statistics.
Both files have assigned -999 to 'No Data Value' but'STATISTICS_MINIMUM'
for one file shows

Hello,
I have a curious problem with 'gdalinfo' (gdal version 1.9.0 ).
I have an input ENVI file with the following .HDR entry:
data ignore value = -9.9900e+002
gdalinfo for the IMG file provides stats that exclude all values -999.0 as
expected.
I then create a masked output file using
;s just as easy either way.
Thanks again,
Peter

Hello,
Is it possible to use ESRI SHP polygon file to mask
ENVI BSQ img format files with more than 1 band?
I can mask a GTiff file using the SHP but ENVI file does not
appear to work. Gdal version is 1.6.3 .
The documentation appears unclear for any raster that is not
specifically GTiff.
