This page is about support of OGC web map services (WMS) in GRASS GIS.
Metasites and collections of WMS servers
- Extensive catalogue of OGC web map services (WMS) worldwide
- Telascience WMS services (in collaboration with OSGeo): see list at http://wms.telascience.org/
Italian Public administration WMS
Example for public administration data imported via WMS into wxGUI
NASA's OnEarth WMS Example
Web_Map_Service (WMS) data can be downloaded and imported into GRASS using the r.in.wms module. Mini tutorial for downloading SRTM elevation and LANDSAT imagery from NASA's OnEarth WMS server.
Create a NZTM location (EPSG:2193) with the location wizard.
# Zoom to AKL region
g.region n=5936130 s=5900340 w=1740030 e=1776030 res=30
If downloading for your own area, try to keep the region rows and columns smaller than the maxrow,maxcol options given to r.in.wms. Please don't abuse the server, just download small chunks.
### Download and process SRTM elevation:
r.in.wms output=akl_srtm \
mapserver="http://onearth.jpl.nasa.gov/wms.cgi" \
-c layers=worldwind_dem format=geotiff style=short_int \
maxcols=1600 maxrows=1600
g.rename akl_srtm.1,akl_srtm
r.colors akl_srtm color=srtm
### Download and process LANDSAT:
r.in.wms output=akl_landsat \
mapserver="http://onearth.jpl.nasa.gov/wms.cgi" \
-c layers=global_mosaic_base format=geotiff style=visual \
maxcols=1600 maxrows=1600
i.landsat.rgb -p r=akl_landsat.red g=akl_landsat.green b=akl_landsat.blue
d.rgb r=akl_landsat.red g=akl_landsat.green b=akl_landsat.blue
r.composite r=akl_landsat.red g=akl_landsat.green b=akl_landsat.blue \
output=akl_landsat --overwrite
### Shaeded relief map
r.shaded.relief akl_strm
d.shadedmap relief=akl_strm.shade drape=akl_landsat bright=70
### 3D view
nviz akl_srtm color=akl_landsat
In the NVIZ (or wxNviz) Visualization → Raster Surface menu set the fine raster grid size to 1. Set the vertical exaggeration to 1.0 or 2.0
MetaCarta WMS Example
Create a NZTM location (EPSG:4326) with the location wizard.
g.region n=90 s=-90 w=-180 e=180 res=0.5
r.in.wms -c output=map \
mapserver="http://labs.metacarta.com/wms-c/Basic.py" \
layers=basic format=geotiff \
OpenStreetMap WMS Example
Note: European coverage:
r.in.wms url=http://watzmann-geog.urz.uni-heidelberg.de/cached/osm layers=osm_auto:all output=osm format=png r.in.wms url=http://irs.gis-lab.info layers=osm output=osm format=png
