Virtual Raster Builder

VRT Builder Logo

Description

The Virtual Raster Builder is a tool to create a GDAL Virtual Raster (VRT) by drag and drop. It can be used to stack and mosaic rasterbands or to create spatial- or band-subsets.

Workflow

To build a new virtual raster (VRT) follow these steps:

  1. Add potential source files to the list of source files:

    Button Action
    add source raster add source raster
    remove source raster remove source raster
    import from QGIS load raster known to QGIS
    expand tree node expand source file tree node(s)
    collapse tree node collapse source file tree node(s)
  2. Specify the VRT structure by drag and drop of source bands

    Button Action
    add virtual band add virtual band
    remove virtual band remove virtual band
    import virtual bands from existing VRT file import virtual bands from existing VRT file
    expand tree node expand VRT tree node(s)
    collapse tree node collapse VRT tree node(s)

    Virtual band names can be changed by mouse double-click.

  3. Specify other VRT settings:

  4. Save the new file as VRT. In case of output formats other than VRT, e.g. GeoTIFF, the VRT is created in a temporary location first and the binary file afterwards using gdal.Translate
