[HOT] Chequerboard Pattern

[Martin Noblecourt]

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 ;-)

Martin

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.

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.
