Re: [gdal-dev] ogr2ogr.py

Mike, Thanks for the update. But, I have to mention that the python scripts are primarily to serve as examples. You can submit a ticket (bug report) on gdal trac and attach a diff patch along with the description. http://trac.osgeo.org/gdal/#BugTracking One of the committers should pick it up.

[gdal-dev] ogr2ogr.py

Hi ​ I've updated ogr2ogr.py with a really small change which is to accept the -dialect parameter that is now available. I'm wondering how / what the process is for submitting back. ​ ​If someone could let me know or pointing me

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

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've been using gdal_calc.py

Re: [gdal-dev] MSG Driver: two memory leaks

Hi, I haven't noticed any other leaks, but I haven't used the Reflectance Calculator, either. Should I stumble upon more leaks, I'll either report or fix them. If you want to know if the "memory usage" you noticed is just "usage" or an actual leak, valgrind ( http://valgrind.org/ ) is awesom

Re: [gdal-dev] MSG Driver: two memory leaks

Hi, Have you noticed any other memory leaks in the MSG driver? We have seen some huge memory uses when working with the visible MSG channels (converting from DN to Reflectance) but have not been able to track down where the memory is being used. Would be good to have a second opinion! All the b

Re: [gdal-dev] gdalinfo: fix metadata output

Hi, yes, I'm talking about metadata in a custom domain. I hacked up a driver to return additional metadata I want to use; since that metadata is driver specific I put it into a custom domain named after the driver. If you guessed MSG driver you'd be correct; but the SVN version doesn't retur

Re: [gdal-dev] gdalinfo: fix metadata output

Christian, I guess you are talking about metadata in domains other than the default and IMAGE_STRUCTURE metadata domains ? With which driver did you experiment that issue ? Would you mind attaching your patch as an attachment to a ticket in Trac ( http://trac.osgeo.org/gdal/newticket ) ? For that

[gdal-dev] MSG Driver: two memory leaks

Hello, valgrind'ing my application revealed two memory leaks in msgdataset.cpp. a) MSGDataset::pszProjection shall always point to a valid string during the lifetime of the object; the old string needs to be released before getting a new one from exportToWkt(). b) A spatial reference is expo

[gdal-dev] gdalinfo: fix metadata output

Hello, I tried getting a driver to return some useful metadata from the files, but gdalinfo never displayed any of it. As it turns out, the culprit was gdalinfo. It will never report metadata from the bands, even if explicitely requested in the command line. So I set out to rewrite the metad
