<br>Jeffery,<br><br>Thanks for your quick reply. I have been checking the wiki periodically for info on new imagery assets and also noticed some mention of it in the IRC forum mentioned there. Problem is that I assume new DG data will be updated with the same alias in the Potlatch editor (JOSM gives me a headache since I am so amateur and I just want to get stuff done right now). So, despite hearing it was/is being updated, I am not sure what I am looking at from DG (GeoEye is a good counterexample, where there is a distinction between imagery from before and after 13 January in the dropdown box where you can select overlays).<br>
<br>So, with that in mind, I will hold off for a bit until more becomes clear. I heard that the ERDAS imagery may be up and running? I will check with that later.<br><br>Again, thanks for the info. I wanted to work on street names based on data we got from other sources, but the roads are so convoluted I could not cross-reference as easily as I had hoped.<br>

</div>Right now there are two sets of images that cover Jacmel, the<br>
DigitalGlobe data from last week and the JAXA/ALOS satellite imagery.<br>
As far as I know, most of or all of the satellite imagery we have<br>
access to now isn't very well georeferenced so you may need to adjust<br>
the image to get a "rough" fit before doing any corrections and/or<br>
traces.<br>
<br>
You can see what we know about by checking out the following relation:<br>

There is some new data from both Digital Globe and GeoEye being<br>
imported so check the wiki page for updates.<br>
