I think that tracing in the presence of trees can be done an match
the most up to date imagery OSM has. Similarly rivers, roads etc. <br>
<br>
There is a temptation to 'colour in' the map .. many National Parks
'local' to me were tagged as tree covered. I have reduced that by
separating the tree tags from the National Parks and mapping the
trees separately. In at least some areas I suspect that the 'trees'
are really scrub .. but until I go there I cannot tell. Were the
original mappers wrong to do this? I don't think so - most of these
are mostly covered by trees, so as a broad brush they were correct
and the indication was in a broad sense correct. But it lacked some
detail that I was able to add .. by using imagery remotely! However
I do have some local knowledge to aid me. <br>
<br>
Remotely mapping some things is possible, roads and rivers, tree
cover are all possible with caution. Remotely mapping use of those
trees is not possible, nor is the type of tree.. more information
than the imagery provides is necessary. <br>
<br>
If we all seek to improve the map .. things will simple get better.
I call it polishing, you start with what there is and polish it to
improve it, removing rough bits, clearing up bad spots. <br>

<div>I'm fairly lucky in that in the last three
years nothing much has changed locally. The
highways have stayed much the same. Most
buildings are still there.
<div> </div>
<div>If you use Bing to add things then
realistically it fills in gaps in the map. If
you delete things because they are not in Bing
that is a quite different matter.</div>
<div> </div>
<div>Does it matter if the mapper lives more
than five miles away? Well I've mapped places
a few thousand miles away but they were places
I knew very well as I used to live there.</div>
<div> </div>
<div>I don't think OSM will ever be completely
accurate. Having said that it is still very
useful for many purposes.</div>
