Over de talenkwestie zeg ik maar niet teveel, enkel een "bravo" voor de
oproep tot objectiviteit.
Maar inhoudelijk heb ik wel zo mijn vragen: wij mappen toch "in
principe" enkel dingen die zichtbaar zijn in het landschap? Die antennes
van BIPT die hangen toch meestal op bestaande faciliteiten, hetzij een
mast die voor iets anders was opgezet, of een watertoren, een kerktoren,
of wat dan ook? Uiteraard mappen wij wel die masten en torens, maar om
de antennes als dusdanig te mappen? dat lijkt me strijdig met het
basisidee om enkel zichtbare landschapselementen te mappen.
No comments on the matter of languages, in this complicated and delicate
country; save for my compliment and support for the appeal for objectivity.
But regarding "the root of the matter" I do have my questions: didn't we
have a rule to map only those features visible in the scenery? The BIPT
antennae (sic!) are usually attached to existing structures, such as
church spires or GSM masts or so? Of course we map those highly visible
carrying structures, but to map the individual antennae seems to me like
overdoing things.

Hello there
Small detail, I believe it makes more sense to use the abbreviation
BIPT instead of IBPT, since it is "Belgian Institute for Postal
services and Telecommunications" in English and both Dutch and German
also have BIPT as the abbreviation.

Hello everyone,
Recently, we got the permission from ibpt.be <http://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
<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!
