[OSM-talk] Mapping South East Haiti

[Karl Guggisberg]

Hi Vincent,

this is a very large area you're pointing at. Are you interested in the 
complete area between PaP in the north and Jacmel in the south?

The satellite imagery you see in the background on 
http://projekte.eiops.de/osm-matrix/ 
<http://projekte.eiops.de/osm-matrix/?zoom=12&lat=18.3032&lon=-72.45866&layers=B0FTFTFFFFFFFT> 
is from one set of images only (I believe its from GeoEye,
either  GeoEye1 or Ikonos).

In the south we have imagery provided by DigitalGlobe, here's an example:
   
http://www.openstreetmap.org/edit?lat=18.28266&lon=-72.51776&zoom=17&tileurl=http://maps.nypl.org/tilecache/1/dg_crisis/!/!/!.jpg 


There are two interpretations for the colors of the tiles:
* if a tile is colored somebody who new this tracking tool has most 
likely been mapping in this area (there are large mapped areas in Haiti 
which are not (yet) tracked in this tool, though)
* the darker the green of the color the more complete is the mapping in 
this tile

Note that there are  huge differences in the level of detail and the 
accuracy of the mapped tiles over the country, mainly because the 
quality of the available imagery isn't homogeneous. DigitalGlobe imagery 
around Jacmel can't be compared with Googles imagery available for PaP.

Regards
Karl
