Hi Vincent,<br>
<br>
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? <br>
<br>
The satellite imagery you see in the background on <span
style="color: rgb(31, 73, 125);" lang="EN-US"></span><a
moz-do-not-send="true"
href="http://projekte.eiops.de/osm-matrix/?zoom=12&lat=18.3032&lon=-72.45866&layers=B0FTFTFFFFFFFT">http://projekte.eiops.de/osm-matrix/</a>
is from one set of images only (I believe its from GeoEye,<br>
either GeoEye1 or Ikonos). <br>
<br>
In the south we have imagery provided by DigitalGlobe, here's an
example:<br>
<a class="moz-txt-link-freetext" href="http://www.openstreetmap.org/edit?lat=18.28266&lon=-72.51776&zoom=17&tileurl=http://maps.nypl.org/tilecache/1/dg_crisis/!/!/!.jpg">http://www.openstreetmap.org/edit?lat=18.28266&lon=-72.51776&zoom=17&tileurl=http://maps.nypl.org/tilecache/1/dg_crisis/!/!/!.jpg</a>
<br>
<br>
There are two interpretations for the colors of the tiles:<br>
* 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)<br>
* the darker the green of the color the more complete is the mapping in
this tile<br>
<br>
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.<br>
<br>
Regards<br>
Karl<br>

<p class="MsoNormal">Hi Vincent<br>
<br>
We have been mapping Jacmel city in the past three days. The city
itself an
east up to Catadat, north up to Bassin Caiman, and west up to
Desmarattes is
mapped as good as possible. The area is covered by DigitalGlobe imagery
whose
quality is, unfortunatelly, not homogeneous. <br>
Jacmel center has been enriched with street names and POIs provided by
MINUSTAH.<br>
<br>
Depending on which rural areas you are most interested in GeoEyes
Ikonos
satellite provides coverage too, but only more up north. <br>
<br>
Have a look at this site: <a moz-do-not-send="true"
href="http://projekte.eiops.de/osm-matrix/">http://projekte.eiops.de/osm-matrix/</a>.
Can
you tell us what tiles in this matrix you are most interested in? <br>
<br>
Regards<br>
Karl <br>
