Description

r.in.wms handles all of downloading and importing raster data from an 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)

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’.
