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.
