Using QGIS I have to merge 416 raster files with elevation data, at the beginning I´m using with only 4 of them to try out:

  • When using "merge" (Raster > Miscellaneous) the result are a file with only black and white which have not included all the raster files i selected.

  • With "build virtual raster" (Raster > Miscellaneous) I get the merged file but with a different colour scale. I don´t know if it would affect further analysis.

  • And with the SAGA tool "Mosaic raster layers" the grid file could not be generated.

I have tried modifying some options without success.

How do I maintain the colour scale when using "build virtual raster"?

  • What format are your rasters in? Could you share a sample? Maybe is only happening on your machine. – alecsx Aug 8 '17 at 21:20

    Rasters are in TIF format, I have solve the problem. "Build virtual raster" worked when I loaded all 416 file in the layers panel. Before I only selected the directory. – Javier Aug 9 '17 at 8:10

"Build virtual raster" worked when I loaded all the files in the layers panel. Before I just selected the directory in the "build virtual raster" window, and it didn´t worked. For the last I save the new VRT file as a raster layer.
