[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 Geo

No comments on the below anyone? It does seem like a genuine bug that gdal_calc.py can produce output with statistics not up to date? Should I create an issue in the issue tracker? -- Patrick. On Thu, Jun 19, 2014 at 2:45 PM, Patrick Sunter wrote: > Hi there, > > I'

[gdal-dev] NetCDF and datum handling suggestion

2011-09-05 Thread Patrick Sunter
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 . Here

arly you can specify Proj4 from the command line to commands, but not sure you can ask it to store this, will do some checking. > > BTW, there is a "CF-NetCDF 1.0 Standards Working Group" part of OGC, > perhaps we can discuss with someone from that group? > http://www.opengeospatial.o

[gdal-dev] Can't get gdalwarp to create a raster in Mercator-2SP projection?

2011-09-28 Thread Patrick Sunter
Hi, As part of testing GDAL's NetCDF drivers projections, I've been trying to gdalwarp a Geotiff file from a UTM projection to Mercator-2SP (http://geotiff.maptools.org/proj_list/mercator_2sp.html). Thinking I should file this as a ticket? But thought I'd post here first. I've tried 2 approaches

Hi Dan et al, in addition to the replies below, you might find the following GDAL Wiki pages useful, I read them when starting to contribute some work on the NetCDF driver: http://trac.osgeo.org/gdal/wiki/HowToContribute http://trac.osgeo.org/gdal/wiki/rfc8_devguide http://trac.osgeo.org/gdal/wiki
