I am glad you added a palm symbol to http://wiki.openstreetmap.org/wiki/Tag:natural%3Dtree#Possible_Rendering. When I created the conversion table in that section, I wondered why there is no palm symbol. I believed that I had already seen a palm symbol somewhere in the wiki, but I didn't manage to retrieve it. Then I searched google for palm symbols, but did not find anything either.

If broad and needle leaved trees get different symbols, palms should get their symbol as well because of their distinctive look. And - but that's just my subjective opinion - palm symbols look so cute that a map becomes more appealing when it incorporates them. Concerning tagging, there has been an approved and widely used key for a long time with exactly the values we need to distinguish palms, needle leaved and broad leaved trees. This key is type=*.

And wood=* has just another purpose. While type=broad_leaved/coniferous/palm defines the *habitus* of a single plant, wood=* describes a *behaviour* of an area. wood=evergreen means that assimilation (photosynthesis) does not change much with the seasons, and that the tree crowns remain continuously opaque. wood=coniferous means that the crowns are constantly semi-opaque, and that assimilation remains also at an intermediate level. wood=deciduous means that both assimilation and opaqueness have big seasonal amplitudes. This tag has enourmous ecological and econimical implications, and it may also be used to determine good times for documention (photographing, creating arial images) and recreational use.

Re: [Tagging] Leaf type of "palm" for leaf_type
I oppose this suggestion. The key:leaf_type should be as simple as possible. Palms are included in leaf_type=broadleaved. The values relate to the Land Cover Classification System (LCCS) by FAO. I don't know any classification systems with leaf_type=palm. To refine the tagging you can use key:species or key:genus or key:taxon. I'm not sure which will fit the best. Gesendet: Dienstag, 10.

Re: [Tagging] Leaf type of "palm" for leaf_type
It would be harder to process and break existing data consumers. I think that cascading tagging style - [leaf_type=broadleaved; broadleaved=palm] would be better. It provides full information without growing list of valid values of leaf_type. 2015-03-11 2:32 GMT+01:00 Bryce Nesbitt : > On Tue, Mar 10, 2015 at 3:33 PM, Lukas Sommer wrote: > >> So it this seems to me that this is just a special case of broadleaved. >> > > The difficulty is that palms are widely mapped now, and changing type=palm > to leaf_type=broadleaved > feels like removing information.

The "species=" tag is available for that. What you've got there is a good looking list of what's easily observed about an individual tree, which is what most mappers can do. It's pretty close to leaf_type/leaf_cycle and wood, minus the palm trees.

Re: [Tagging] Leaf type of "palm" for leaf_type
Hi, I hope this helps (and that I’m remembering correctly my education from forestry school in the states), In taxonomy of trees there are two kinds of families - gymnosperms and angiosperms, commonly called deciduous and coniferous but actually scientifically separated by their reproductive difference not what their leaves look like, do, etc. More commonly you here layman terms depending on context: -‘Leaf Type’ (the structure of the leaves): needle, broad and/or palm -‘Leaf Retention’ (if they fall off or not): evergreen, autumn/broad, and/or Palm - ‘Wood Type’ (for wood product industry): soft, hard, exotic/ornamental Maybe we need a key/value for each 'category'; and genus and species is probably best for 'micro-mapping' individual trees or maybe scientific_name=[genus_species] and/or common_name=* example pinus_ponderosa / ponderosa_pine Wish I had more time to work on a proposal/update/upgrade to the wood/natural tagging, but can help answer questions (was going to chime in about the diameter/crown discussion – there’s a whole slew of measurements and how to make them regarding individual trees versus forest plots/stands, etc.) Cheers, =Russ Russell Deffner ___ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging

Re: [Tagging] Leaf type of "palm" for leaf_type
There are places where there are an amazing mount of Palm trees, and confusing them with a broadleaf tree is not great. But is this the main way the species (or class or whatever) of tree is defined? it thought there was some species tag for this as well - or is it too difficult when mapping to know the type of tree beyond it’s leaf? It would be nice if trees marked get a color or shape at extremely high zoom (z19?). Many park maps in Japan map the trees (yes, individual trees) as to what color stereotype it’s blooms are. (soft pink dots for cherry, magenta for plum, etc), as people often go looking in the parks for the blooms in spring.

Re: [Tagging] Leaf type of "palm" for leaf_type
“palm” is described explicitly as an example at http://wiki.openstreetmap.org/wiki/Tag:leaf_type%3Dbroadleaved So it this seems to me that this is just a special case of broadleaved. I have doubts in adding a new value which is just a special case of an existing value – in the same key. We loose the hirarchy.
