Hi all, Using gdalwarp, I have generated two mosaic images for same area. MOSAIC1 :One image is 2-byte(12-bit data values : 0-4095) and MOSAIC2 : Another is 1-byte ( actually having 0-3 values only)
I am trying to view the images using openev. First I open 2-byte mosaic (MOSAIC1) then I overlay 1-byte mosaic (MOSAIC2) over it. I click the classify button for the MOSAIC2 and choose discrete values as classes, it lists only 1,3 and not 0 even though there is 0 in the mosaic. I want to make all 0's transparent and see only 1,3 values regions overlaid over 2-byte data. For this , I usually set 0's class as transparent but since 0 is not listed at all I am not able to set it transparent. I tried to use "Add Class" option and added 0 class explicitly but that also doesn't work. [Using gdal 1.4.5 ] The input images using which I generated the MOSAIC2 have 0's and on clicking classify, 0 is also listed for them. Can someone help me understand why only 1,3 are listed for MOSAIC2 inspite of it having 0,1,3 values. -- View this message in context: http://osgeo-org.1560.x6.nabble.com/openev-py-classify-option-tp5061559.html Sent from the GDAL - Dev mailing list archive at Nabble.com. _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
