Trees and tree types; towers; rest & service areas




> highway=services already exists at line 166

Yes, but it is currently not considered as POI, so you cannot search it and display it on the map, which would be very useful when you travel on motorways/large roads.


>tower:type=communication is used 59529 times (taginfo) while 
man_made=communications_tower is used 2 (!!) times in the world. I 
disagree with this change.

man_made=communications_tower is used 3015 times (don't confuse with communication_tower without s). It is a very useful landmark, so it is useful to display as POI.
tower:type=communication is useful too, but currently it appears in POI list (man made → communication), but if you filter only "communication" OsmAnd doesn't find anything. That's why I didn't delete it but move it in additional (new line 133): 

<type tag="tower:type" minzoom="13" additional="text" only_poi="true"/>
As the difference between man_made=tower + tower:type=communication and man_made=communications_tower seems to me very thin, maybe we could propose that :
<type tag="tower:type" value="communication" target_tag="man_made" taget_value="communications_tower" minzoom="13" poi_category="man_made" />

>This is a little bit too detailed? Actually recently I was wondering why do we need forests as POI.

I understand that genus/species/taxon/leaf_type/wood may be considered as too detailed.
I think genus/species/taxon could be interesting when you're looking for particular trees (e.g. in a garden, a park). But I don't think it is absolutly necessary.
Concerning trees as POI, somebody recently ask for it in the forum: https://groups.google.com/forum/#!topic/osmand/YcR5uSPGXKY As I said to him, trees are POI as much (more?) useful as ditch, drain, mud, stone...
Concerning forest as POI, I strongly support it is needed! If a user is looking for a particular forest, he wants OsmAnd to be able to find it without scrolling the map. Moreover, when you're walking, especially in mountain, it could be useful to know the kind of leaf_type/wood since it is something you can easily distinguish in the landscape (that's why I also think it should be rendered on the map).
