Add support for WMS layer in tm_raster #502

Open marionowak opened 4 years ago

marionowak commented 4 years ago

Is it possible to add a raster WMS layer as background for a map? I think this could be added to tm_rgb(). Similar to leaflet::addWMSTiles():

leaflet(map) %>%
  addTiles() %>%
  setView(lng = 8.21831, lat = 56.78995, zoom = 15) %>%
  addWMSTiles(
    map="WMS_URL",
    layers = "layer name", 
    options = WMSTileOptions(format = "image/png", transparent = TRUE),
    attribution = ""
  )

Great idea! Do you think it can also be used in plotting mode? I'm not very familiar with WMS yet, but from what I've read, it should be possible. I used to have the distinction between zoom-dependent tiles (tm_basemap/tm_tiles) on the one hand, and static images on the other (tm_raster/tm_rgb), but it seems WMS could serve both.

Does any of you have a reproducible example of using WMS in R?

There's a nice example here, though only interactive...
