[OSM-talk-be] IBPT antennas

[rodeo .be]

Hello Vucodil

fantastic news from the BIPT. I would advise you to ask the BIPT to share
the list as well on the federal government open data portal
<https://data.gov.be/>. It is only a small step for them now (they already
approved us using the data).
I see some advantages in that: it will stimulate other federal
organisations to do the same, and they'll be (hopefully) more inclined to
keep the list updated with new antennas and operators.

Other question: how will we keep everything up to date? Imagine a new
version of the list is released in 1y. How can we easily check the
information on OSM is up to date?
