2.15. Prepare raster

A tool that performs a per-band connection of a set of single-band rasters and crops the result using a vector mask.

Input:

  • Initial raster data

The initial raster data can be presented in two forms:

  1. Multi-band raster in GDAL-compatible format

  2. ZIP archive with a set of single-baned GDAL-compatible rasters

  • Vector layer, which is used as mask

ZIP archive with ESRI Shapefile or a other file format supported by OGR.

  • “No data” value

The value that is marked as “No data”. Use the - symbol to use the default value.

  • The name of the resulting raster

No file extension (e.g. ndvi, water). The extension will be automatically installed in .tif

If the input is an archive with single-band rasters, the tool first combines them into a multi-band raster. The order of the bands is determined by alphabetically sorting the names of the initial rasters in the archive. Then the multi-band raster (assembled from the archive or submitted immediately) is cropped with a vector mask.

The initial rasters and the vector mask can be in different coordinate systems before processing, all data is brought into a single spatial domain.
