Hi, The "-skip_different_projection" option in the gdaltindex utility http://www.gdal.org/gdaltindex.html has some analogy with your suggestion. You did not define the meaning of "same" and "different" resolutions. Would you like to give the "right" resolution by hand or should all the files be pre-scanned so that user gets a list of all different resolutions that appear in the data? I feel that your need is rather specific for a general purpose tool like gdalbuildvrt. What if you write a Python file filtering script and publish that for example in https://trac.osgeo.org/gdal/browser/trunk/gdal/swig/python/samples, topped up with a manual page in the user wiki section? Such script could be made to filter the source files according to other criteria as well: SRS, band count, bit depth, metadata etc. -Jukka Rahkonen- -- Sent from: http://osgeo-org.1560.x6.nabble.com/GDAL-Dev-f3742093.html _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev
