[OSM-talk-be] IBPT antennas

[Karel Adams]

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.
