GRASS GIS Manual: r.in.wms2.py

NAME

r.in.wms2.py

DESCRIPTION

r.in.wms2 handles all of downloading and importing raster data from an OGC WMS, OGC WMTS and NASA OnEarth Tiled WMS web mapping servers. It needs only be told the desired data to collect (bounds and resolution) via a region, the server to get the data from, and the layer or layers to get. It downloads the data in tiles, reprojects it, imports it, and patches it back together.

NOTES

To understand the data you are getting it is necessary to look at the capabilities of the WMS server. This should be available via a capabilities request. This is an example capabilities request to NASA's OnEarth server.

NASA OnEarth Tiled WMS

Into parameter layers insert name of TiledGroup from Tile Service file.

Time variable is possible to specify in urlparams parameter.
e. g: urlparams='time=2012-1-1'
