[GRASS-user] workflow to import/georectify binary remote sensing data

["Peter Löwe"]

Hello list,

here is a question about what's currently the most effective way to ingest binary raster data which need to be georectified.

The data source are calibrated weather radar precipitation rasters (lots of them), which come in a well documented binary format (+ GCPs), which is not (yet) supported by gdal.

A "classical" approach could be:

1) Create XY location as source
2) Create LatLon location as target
3) Ingest data via r.in.bin (to skip over file header) into XY location
4) Use GCP to set up i.rectify within XY location
5) Apply i.rectify
6) Discard XY-location and continue work in LatLon location

In there a more effective way, probably without using a XY location ?

best,
Peter
