SPW's PICC orthorectified precision<25 cm Wallonia map

PICC is a must to map Wallonia, much preferably with JOSM. This link describes its contents.

This page explains that SPW, the PICC's © owner, allows to trace the WMS service without restrictions.

The JOSM PICC layer is available in:

Imagery>Preferences>Imagery Providers>Available Default Entries>BE SPW(allonie) PICC numerical imagery
Here is a legend of the map.

PICC is made from aerial photographs with a precision better than 25cm.

They are digitalized and orthorectified.

This means that errors due to the obliqueness of the photography are corrected, a thing impossible to do "manually".

Although PICC is available since 2010, the SPW has corrected a bug and made the © matters clear only in 2016, so that contributors have mapped Wallonia by other methods with a 2-3-5m error or even more during that time and that that work has to be redone again.

For the PICC, what "copying" means and what can be done by "tracing" is rather clearly defined in its Conditions on SPW's site.
With PICC, one can do two things (see the titles):

Obtenir une copie de la donnée (= get a copyof the data)

that is copying (downloading files) and the conditions are:

Consulter (= browsing = what OSM does : tracing VIA A WEB SERVICE)

that is browsing or tracing and the conditions are:


Would anyone be in an urgent need of a "license name" for"consulter", it is "public domain".
According to the "Conditions particulières de type B1", the "copying" of PICC's data is subject to

  1. a possibly payed license

  2. be signed between SPW and the user

  3. for only a well defined, agreed part of Wallonia

  4. over a limited period

  5. for an agreed restricted use.

That kind of contract obviously cannot have a conventional license name. But that does not apply to OSM.

Please use it with its perfect companion JOSM.

Suspecting that some vigilantes could not agree with what I understood and wrote here above, I wrote and explained the SPW Carto what OSM does with maps (tracing, which they already knew) and I asked them to produce a clear explanation of what is allowed (which I had already understood).

Please note that this answer letter is an official statement, written with the help of their lawyer. Regarding "I [don't] care what certain persons from PICC said to someone else I don't really know", there is no need to personally know those persons, nor me, more than the persons who announced Bing's public domain.

for your help, Papou.

SPW Cartopro's clarification letter

Subject: RE: Utilisation du PICC pour Openstreetmap

From: helpdesk.carto <

Les utilisations que l’utilisateur peut faire sont :

  • se connecter sur le serveur du SPW et calquer le PICC afin de faire des fonds de plan (=vectoriser),
  • réutiliser à sa guise les fonds de plan (1) (commercialement ou non),
  • ne peut pas copier le PICC (2) sur ses serveurs à des fins non-commerciales, sauf autorisation préalable du SPW (les conditions particulières d’accès et d’utilisation s’appliquant aux PICC ont normalement été écrites par la Géométrologie et devraient être en ligne pour être opposables aux utilisateurs),
  • ne peut pas copier PICC (2) sur ses serveurs et les réutiliser à des fins commerciales (les revendre ou permettre à ses utilisateurs de les revendre),
  • ne peut pas, non plus, recréer le service sur ses serveurs, sauf autorisation préalable du SPW.

(1) Les fonds de plans sont le résultats de la vectorisation que vous réaliserez sur base du service.
Il s’agit là, du résultat de votre vectorisation basée sur le service du PICC. </p>

(2) Le point relatif à la copie du PICC concerne les données vectorisées que nous distribution. Dans votre cas, cela ne vous  concerne pas.

Je reste à votre disposition.
