For those interested in Wallonia, here is a summary of the "Rencontre des utilisateurs du PICC" ce 21 juin 2018.

PICC and first contact with them

The PICC is definitely going to be open "soon", it should be voted in a few weeks. PICC age by municipality is decreasing! It is 6.5 years of median age (down from 7.5 years last year), as many “old” municipalities have been reworked. An objective is to get better 3d precision in PICC (x,y,z coordinates) with high quality gps points for the main elements. Also the PICC will get two diffusion method (monthly update and later on maybe every day or week): one complete file and one difference file (so practical for update).

=> ONE important note for mappers: they cleaned 300.000 “double entry” of buildings (“doublons” in french) in the PICC (visible in the next release of June) as an older conflation between IGN and Wallonia source had been made badly. So if you edit after the update of this month, we should no longer see the weird overlapping buildings!!!

A Good point for OSM: The director of PICC, lidar... department (“Département de Géométrologie” in French) at geoportail Wallonia is very welcome about Osm and open to collaborate with us (but we still need to wait the formal opening of the data). In fact they are looking to be as up to date as possible with the long term objective is to get an age of the data of 1 years (at least <2 years). To do it, they want to get different ways where they will be notified of change and Openstreetmap is a possibility but also other crowd-sourcing methods (like an application where municipal employee could say that a change occurred in one road…).

He talked about ICAR (address's data) and it is 90 % complete (still completing with some municipalities: missing 29 out of 262 municipalities) and will be open with the same licence than PICC (when PICC will be open, ICAR data will follow as they are really just waiting for the licence).

Wallonia is planning a “georeferentiel” (base of layers that are high accuracy and authentic source) within the application of INSPIRE.There are 4 major datasets that will be made as accurate as possible and with one authentic source for each:

  • buildings (in PICC),
  • admin limits (in cadastre),
  • addresses (in ICAR) and
  • Roads (in PICC/”direction des routes” collaboration with attributes (like primary, secondary, highway, bridge,…) on road, not only geometry).

New orthophoto in progress (and will be complete, as “2017 orthophoto” was missing most of Luxembourg province and south of Namur province). A new compaign of LIDAR is in planning, it will be denser but the point cloud will not be proposed in download on their website (only by specific request) as they don’t want to overload their server with too many download of the point clouds (at least it is not a priority).

3d building is not a priority either (as it is costly to use high resolution LIDAR for the whole region) but we will probably get the height of buildings… (The objective is to get a complete coverage more than a great detail at the moment -> so not more than LOD 1 of 3d buildings).

WALOUS

Other subjects: “WALOUS” project is making a very detailed landcover map and then they will make a detailed landuse map of Wallonia. The objective is to get a detailed map pleasing as many people as possible and compatible with European standard (Corine Land cover…), it is entirely open project (open-soruce software and result will be open) made by universities in Belgium. That could help to map a lot of place with details! :D

Contact with La Louvière

A last good point for OSM : I also met the "Geometician/Geographer" of La Louvière (the municipality) and he told me that he was using OSM data as it was useful for them (to get the position of parkings for example). He wanted to know how to contribute and if he could notify us of changes (like with mobility plan), i told him that he could try contributing himself and contact us without problem and ask about any questions (via the mail or chat). He got the "open data" mindset so he is intersted in OSM and really want to give something back. He was also asking about the number of municipalities that were contributing to OSM in Belgium (so he could push it to his boss as an argument that it is not only them doing it -> it will probably come with the e-mail as a question). Last thing, he was possibly interested in organizing a mapathon to complete some aspect of the city (like bicycle route...) [To be decided/discussed].
