Araucariaceae happens to be my favourite gymnosperm, but why get all technical? 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. Existing land cover databases mostly talk about forests, not trees: http://bioval.jrc.ec.europa.eu/products/glc2000/legend.php http://landcover.usgs.gov/classes.php#upland And mapping individual trees, as many people are doing for whatever reason, is slightly different. _______________________________________________ Tagging mailing list Tagging@openstreetmap.org https://lists.openstreetmap.org/listinfo/tagging
