I am trying to create a tiff file using gdal_translate.
noDataValue was 0.0, but my client suggested that
- noDataValue should be -9999.0, so I changed it to -9999.0.
gdal_translate -of GTiff -a_nodata -9999.0 -a_srs EPSG:4326 -a_ullr -26.62 45.099999999999994 75.46 -6.82 -co INTERLEAVE=BAND -co TILED=YES -co COMPRESS=LZW -ot Float32 shape_19790101.tif shape_19790101_optimized.tif
But now I am getting following suggestion
You set the noDataValue to -9999, but you did not recompute the imagine and change the value of the "noDataPixels"
Can anybody explain what exactly this means ?
