DESCRIPTION

r.dtm.import downloads and imports digital terrain models (DTM, in German DGM) for specified federal state and area of interest. Alternatively, local data can be imported. Implemented federal state options are:

Baden-Württemberg (BW): only local data import
Bayern (BY): only local data import
Brandenburg (BB)
Berlin (BE)
Hamburg (HH)
Hessen (HE)
Sachsen (SN)
Thüringen (TH)

For local data import the parameter local_data_dir has to be given and the folder structure has to be as follows:

/path/to/DTMs/
├── BW/*.xyz
└── NW/*.xyz
└── ...

In the federal state folders the addons searches for xyz files. If local data does not overlap with aoi, data will be downloaded from Open Data portals if federal state supports Open Data.

EXAMPLE

Use local DTM

Import local DTM with native resolution:

r.dtm.import fs=BW aoi=aoi_BW output=dtm_BW local_data_dir=/path/to/DTMs/ -r
