Can OSM be used to develop a community map ?

Would I use OSM in order to develop a community map (tree survey)? For example can I use OSM as the background and then overlay local data like the results of a tree survey?


We might even like to have the trees in OSM! But certainly think of Umap as the place to start.

Also look at using Field Papers as a way of collecting data :

Someone already made a map with trees on umap:
