Thanks Blake We are happy that these Activations bring in new contributors. This is how I started myself with Haiti in 2010. More then having the satisfaction to help for humanitarian relief, this is a context where we have the opportunity to learn with the community that participate to this action.
I am very happy to be here and hope to share the message about HOT with a few local groups I am part of.
Looking at the edits for Naiyama, I see that they were done by a new contributor using Potlatch 2. He does not provide information about the Imagery he has used. So far he had less then 20 Edit sessions. He does not seem to understand the basic rules of mapping.
JOSM is better to do such a Job. If we use the shorcut key Q, this let's orthogonalize the buildings (right angles). A better and simpler way to proceed, is to add the Building plugin in JOSM and trace using th B shortcut Key.
Interesting, I think learning to use JOSM will be my next step.
Inside the landuse=residential polygon, wee see a second polygon with the place=hamlet and name= tags. There is already a node to identify this place and this polygon should be simply deleted since it does not correspond to OSM mapping standards. I also see some ways with the higway=footway tag. I cannot observe this on the map and these ways are not connected to the highway network. Since this is a small village and the work so badly traced, the best solution to my point of view is to erase and restart.
I understand, very informative, thank you for explaining all of that. I will do as you and Ralf have suggested. As a new person I am very worried about making mistakes that is why I ask so many questions at the beginning.
Cheers, Blake Girardot

I am new to OSM and HOT so please forgive my ignorance. It would seem that if I adjust the one section I am working on to align the background with the previously mapped roads and buildings, it would be throwing off the mapping in other sections on the larger map? Is that correct? Is it a problem? The section that raises this issue for me is this one: http://www.openstreetmap.org/edit?editor=id&#map=15/8.2224/-11.2610 <http://www.openstreetmap.org/edit?editor=id&#map=15/8.2224/-11.2610> specifically the village area Naiyama. If I understand your advice correctly, I would correct the background image alignment to match the roads and some of the buildings and then fix the rest of the buildings in the village.
