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 capabil-
ities 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 in-
serted from Tile Service file. Time variable can be specified in url-
params parameter, e.g: urlparams=’time=2012-1-1’.
