[GRASS-dev] improving v.in.wms

[Vincent Bain]

OK, great !

first you need to register here :
http://api.ign.fr/moncompte/creer
(sorry, IGN web site was redesigned this summer and they dropped the
english version formerly available...)

Then from your account page, you can create a contract (choose the 'Sig'
key type, in french 'Type de clé' set to GIS).
http://api.ign.fr/jsp/site/Portal.jsp?page=myapi&action=createkey&keytype=SIG_MODEL&keylabel=Nom%20d%27usage%20de%20la%20cl%C3%A9
Don't forget to pick items you need from the list of available
ressources (e.g. orthoimagery, maps,...)

You're sent a confirmation email, delivering an APIKey.
With the login/password/APIKey triplet you can run r.in.ign

To avoid getting empty response, I suggest you to create a location
matching some covered territories : for example you can make a location
from epsg code 27572 ("Lambert II étendu"), then set up a region with
these params :

north:      2095180
south:      2094980
west:       920650
east:       920850
nsres:      1
ewres:      1


To obtain orthoimagery on the place :
r.in.ign -m --overwrite apikey=$APIKEY user=$USER password=$PASSWORD
wmtslayer=ORTHOIMAGERY.ORTHOPHOTOS output=test

If you try the -c flag to obtain server capabilities don't be surprised
by the very long delay of the server to return the xml file (depends,
but can be more than one minute)

Here it is,
good luck.

Vincent
