#3246: r.in.srtm: patch to support SRTM water bodies import (SWBD)
-------------------------+---------------------------------
Reporter: stjo | Owner: grass-dev@…
Type: enhancement | Status: new
Priority: normal | Milestone: 7.2.1
Component: Python | Version: svn-releasebranch72
Keywords: r.in.srtm | CPU: Unspecified
Platform: All |
-------------------------+---------------------------------
I developed an enhancement for r.in.srtm to import SRTM water bodies in
the .raw format and .raw.zip format, e.g. from https://dds.cr.usgs.gov/srtm/version2_1/SWBD/
Internally, it uses r.in.bin and is activated by the flag 'w' for 'water'.
Maybe someone can check my changes and take a look if my python coding
Style is ok.

GDAL doesn't support this format by default, reading a little bit more
about the data it seems that is is only the line coast and they also
provide shapefile for this dataset https://lta.cr.usgs.gov/srtm_water_body_dataset
I think the shapefile is more useful than raster, if you really need
raster you can rasterize the vector.

I think the idea is that their raster mask precisely matches what was used
in the processing chain. to reach that with self-rasterized vector maps
may lead to slightly different results.
