Hello everyone,
Recently, we got the permission from ibpt.be to use their data in
OpenStreetMap:
https://wiki.openstreetmap.org/wiki/Import/Catalogue/ibpt_belgium_antennas
This includes all the antennas (more than 9000) managed by the three operators
(Proximus, Mobistar and Telenet) with the info on who manages which antennas
and their localisation.
I wish to import them in a semi-automatic import. But before that, I wish to
have your feedback on the:
General workflow
For the workflow, you can find it at the end of the import wiki page. The main
idea is that the antennas to close to existing antennas will be manually
reviewed.
What do you think about that? Is it safe enough?
Tags to use
As there is around 300 antennas currently in Belgium
(https://overpass-turbo.eu/s/QPC) and considering that this import will bring
more than 9000 antennas, I think the tags of the import should be carefully
chosen.
The tags for the objects related to telecoms are not well defined. Various
sources of information are available (see at the end of this email).
If we choose to only map the antenna itself by excluding the support (mast,
tower, roof, ...), it seems to exist two tags:
- man_made=antenna
(https://taginfo.openstreetmap.org/tags/man_made=antenna#overview)
- telecoms=antenna
(https://taginfo.openstreetmap.org/tags/?key=telecom&value=antenna)
the first one being much more used. That's the one that I suggest. You can see
more details on the tagging here:
https://wiki.openstreetmap.org/wiki/Import/Catalogue/ibpt_belgium_antennas#Data_Preparation
With the data from IBPT, it make sense to only focus on the antenna itself and
not on the support as we don't have any information on it.
In cities, it will usually be on roofs or underground like in tunnels but in
the countryside, it is often on communication towers.
Mapping only the antenna enable us to later map more complex things like in
this proposal
https://wiki.openstreetmap.org/wiki/File:Radio_antennas_mapping_proposal.png
where I really like the separation between:
- antenna
- support
- station
Note that today, most antennas in Belgium are mapped via their support (mast or
tower).
What do you think about the tagging that I suggest? Does it make sense ?

PS: I sent two mails in a week about import. It is a coincidence, I'm not doing
only that!
