DESCRIPTION

       r.in.wms handles all of downloading and importing raster data from OGC  WMS  and  OGC  WMTS  web  mapping
       servers.  It  only  needs  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 (see examples)

       If possible, the EPSG code of the  current  location  should  be  used  with  the  srs  option  to  avoid
       unnecessary reprojection.

       When  using  GDAL  WMS driver (driver=WMS_GDAL), the GDAL library needs to be built with WMS support, see
       GDAL WMS manual page for details.

   Tiled WMS
       Into the parameter layers the name of the TiledGroup need to be inserted from  Tile  Service  file.  Time
       variable can be specified in urlparams parameter, e.g: urlparams=’time=2012-1-1’.
