DESCRIPTION
r.in.srtm.region imports all SRTM tiles covering the
current region or region extents given with region into GRASS,
patches the tiles together and optionally interpolates holes for
SRTM V2.1. The SRTM V003 products are already void-filled.
r.in.srtm.region downloads
Importantly, for the SRTM tiles download a user registration is needed at
https://urs.earthdata.nasa.gov/users/new
In the user profile, two specific applications must be approved in the "My application" tab:
- "LP DAAC Data Pool" application, and
- "Earthdata Search" application.
NOTES
This module only operates in Latitude-Longitude locations (EPSG 4326).
EXAMPLE
Import of SRTMGL1 V003 (1 arc seconds ~ 30m) covering the current computational region:
# run in LatLong location - Sicily East, Italy
g.region n=39 s=37 w=14 e=16 res=0:00:01 -p
# use own credentials here
r.in.srtm.region -1 user="my_nasa_user" password="my_nasa_pw" output=srtm_sicily_1arc memory=2000
r.univar srtm_sicily_1arc
