Dear all,
Just to complete what Ralph said, my colleague who routinely produce
maps from OSM data doesn't consider this a priority issue, they just
ignore the forest landuse data when preparing their map then (although
as cartographer, they would of course enjoy have more data to make their
maps pretty!). The consistency and quality of the road network mapping
is a much more important challenge (avoid unconnected roads, road
network on border of projects not necessarily connected to the overall
grid, etc.).
So: don't worry, keep mapping ;-)

Hi kretzer, Russ, Eric, Harry,
I always find it encouraging that others are noting that areas have been mapped
for humanitarian purposes. If it had not been mapped like this there would have
been no mapping there at all (or very limited) and none of you would have been
commenting about any of it.
My first reaction to this is to say A BIG THANK YOU TO ALL THOSE PEOPLE WHO
GAVE THEIR TIME TO HELP WITH THE TASKING MANAGER PROJECTS AND THE MAPPING THAT
YOU ARE DOING IS GREATLY APPRECIATED.
I too would like to see OpenStreetMap mapped perfectly but, as any cartographer
will tell you, you first have to get the basic infrastructure mapped before you
can concentrate on the other details and unfortunately some projects do not get
completed resulting in missing squares ..... or has been run through Mapswipe
first and those squares are not needed by the teams on the ground who are, or
will be, conducting the humanitarian intervention.
It does create work for us because we see those very obvious differences, but
bear in mind that while it is very visual on the rendered OpenStreetMap and
therefore worrying, mapping forests is not a high priority in basic
infrastructure and I would rather see roads, rivers, communities and
agriculture put on the map first and leave the rest of the detail to local
mappers who are better placed to confirm that information. After all some of
the imagery is between two to six years old and drought, logging and seasonal
changes may have altered the landscape since then.
If forestry is your area of interest or expertise then I for one welcome your
efforts to add clarity to the map by checking through and fixing up the
forestry. I would also welcome those who’s interest is in residential areas to
take a look at improving some of those areas that have been previously mapped
for humanitarian purposes as they too have some errors built in.
And thank you for noting the errors and showing that level of concern for the
accuracy of OpenStreetMap, I for one do appreciate that.
Please keep mapping, all of you.
