[gdal-dev] Fwd: gdal_calc.py not saving correct statistics (min/max) to new rasters in some cases?

2014-06-18 Thread Patrick Sunter
Hi there, I've been using gdal_calc.py as part of a workflow where I need to compute the average of several raster files and save as a new output. (Using a binary build of GDAL, v 1.10.0, on Mac Os X). It is a fairly standard calc operation (e.g. (A+B+C)/3) but because the original data are

Hi Etienne and others interested in NetCDF driver, I did some work on WMS display of NetCDF files generated by GDAL today, and it gave me a chance to play around with think about how to handle the Datum issue as described at http://trac.osgeo.org/gdal/wiki/NetCDF_Improvements#Datumissues .
