Hallo Christian,

please, is possible add this?
man_made=tower
tower:type=watchtower
https://www.openstreetmap.org/node/12451430001

and convert to display a similar symbol (tower:type=observation) ?

As it’s use is primarily military, I think that a different rendering to a observation tower makes sense for a map for outdoor use, and maybe make use of access tags, e.g. only render with access=yes.

I added tower=watchtower to tagmapping

conversion as usual

		<name>Transform Towers</name>
		<description>Mapsforge cannot rendert tower:type for some reasons so we have to transform into tower=tower:type, Tower without a type stay untouched</description>
		<match mode="or">
			<tag k="tower:type" match_id="type" v="(.*)"/>
		</match>
		<output>
			<copy-unmatched/>
			<tag k="tower" from_match="type" v="{1}"/>
		</output>
	</translation>

Hi Christian,
just wanted to add tower=watchtower, but only with access=acc_yes|permissive|destination|permit. But access=acc_yes and permissive is missing in tag-mapping… probably wasn’t needed till now because of tagtransform. But adding in for just this case would add 2 million of unneeded access=yes to all kinds of POIs/tags… what now? Only add accessible watchtowers? Or separate them in tower=watchtower_private and tower=watchtower_accessible?
Thanks,
Tobias

Hello Tobias,

I would go the other way and skip tower=watchtower if there is an access=acc_no|private|…. in the theme

I Checked tower:type=watchtower and man_made=tower in my area and there are some I know open for public and none has a positive access tag.

I added access=permissive to tagmapping.

I wouldn’t assume that all watchtowers without access=no are accessible. As the wiki says “it’s primary use is military”, so access=no would be the default in my opinion and access=yes the rare exception.

This would bring 16 watchtowers in whole europe on the map.

None of the, so far I know none_military, watchtowers in lower and upper_austria has access=yes.

Well, thats basicly not our fault that readings manuals is totaly out of fashinon and tagging by chance is common – however it makes rendering watchtowers with access=yes IMO useless.

So the question is how to handle – I can, of couse, eliminate watchtowers w/o access=yes per tagtransform…..

There are some more if you include access=permit and access=customers:

The problem for me – I think the tag is only relevant in my usage with Elevate if a tower is accessible, either as a tourist attraction or like an observation tower. I don’t want to render a symbol for every tower on a medieval city wall, a castle or a prison. So of course lots of those would not be rendered.
I can also live with them not having shown at all – as at the moment the mapping doesn’t really allow to differ between every kind of watch tower and those that are more relevant for Elevate.

I will eliminate all watchtowers w/o

access=yes|permit|customers

per tagTransform.
Then its up to the mappers to tag things in a correct way.
The rule looks a little bit strange but its working.

Best, I think. Locally, someone has mapped all the CCTV masts on the university campus as watchtowers. Hopeless!

Now included in Elevate 5.6, rendered as equivalent to observation towers.
