The SCAN 25®, SCAN 100® and SCAN OACI (and associated online services) are distributed under license conditions that can be consulted [here](https://geoservices.ign.fr/cgu-licences#licence . The final use in a professional or associative context is free without exception, according to the terms of this license. The final use for the general public is free of charge up to a certain threshold, then paying, according to the appropriate general conditions. All infos can be found here.
The SCAN 25® is a unique reference, recognized for its topographic richness, and offers an exemplary representation of the territory (1/25 000)
The SCAN 100® is a perfect compromise between a rather rich topographic representation and a global visualization of the territory (1/100 000
The SCAN OACI corresponds to the aeronautical reference maps in the field of civil aviation
These layers are WMS raster, so you just have to use the
get_wms_raster() function with a personal apikey. To do
this, you need to create an account on the geoservice site and then request
a key in the “My keys” section of your account. It should look like this
: “abc12efghi34j5k678lmnopq” (obviously, this is a fake key).
Then you choose the layer you want at the Web services from IGN SCANs and it’s done !
# Create or import a shape
penmarch <- get_apicarto_cadastre("29158", "commune")
my_key <- "abc12efghi34j5k678lmnopq"
scan25_name <- "SCAN25TOUR_PYR-JPEG_WLD_WM"
scan25 <- get_wms_raster(penmarch,
apikey = my_key,
layer = scan25_name,
res = 1, # To have full resolution
filename = "SCAN25.tif") # This resource need to be downloaded on diskThese binaries (installable software) and packages are in development.
They may not be fully stable and should be used with caution. We make no claims about them.
