I want to create very many ERDAS .img files using GDAL under C++. I don't want to have to process them all in ArcMap to create statistics for them (mainly because ArcMap fumbles when calculating statistics for very many input images in batch mode). I want to create the .img files complete with statistics calculated for each. I see python utilities for this, but nothing under the C++ API. Does anyone have a solution?

What is the context? Are you making these datasets from scratch, or copying them from another source? – kyle Feb 27 at 20:54

GDALRasterBand::GetStatistics() should work for you after you create your datasets and bands, see:

http://gdal.org/classGDALRasterBand.html#a48883c1dae195b21b37b51b10e910f9b

if you are translating data, gdal_translate -stats forces calculation of stats.

Or better: ComputeStatistics – Mike Toews Feb 27 at 22:15
Sorry, was a typo. My link points to ComputeStatistics, Mike is right. – kyle Mar 4 at 17:41
I am creating these from scratch. I'll work with GetStatistics(). Thanks very much. – Frederick Irani Mar 25 at 17:02
