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. This is an example capabilities request to NASA’s OnEarth server.

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.

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’.
