Builds a VRT (Virtual Dataset) that is a mosaic of the list of input GDAL-supported rasters. With a mosaic you can merge several raster files. The algorithm is derived from the GDAL buildvrt utility .
The output resolution of the mosaic. By default the average resolution of th raster files will be chosen.
Options:
Default: 0
With ‘False’ you can define that each raster file goes into a separated stacked band in the VRT band.
Default: True
Allows that the output bands have different projections derived from the projection of the input raster layers.
Default: False
