I'm not a GIS person and RS doesn't ring a bell but as an active OSM contributor living in Haiti here are my few cents:
* Bing imagery covers all of Archaie coast. The imagery is available for tracing to OSM via all(?) OSM tools, at least JOSM and Potlatch that I use). The imagery is also available in various mobile apps and others so I guess it has a standard WMS/TMS api? (I should know by now but I realize I don't) - the imagery has patchy alignment problems in most areas but that wouldn't impact your landcover use and can be fixed for other use (aligning to existing data / GPS traces when available) - the imagery is mostly post quake (for that area) -- _i think_ * OSM wiki has a lot of documentation on both imagery and data sets (even though a good chunk of that is now outdated..). * OSM is very clearly the best freely available (integrated) geo data set for Haiti. As is it only makes sense to use it and contribute to it. It would be nice to meet up when you're here. Give me a call or send a msg and let's have a Cheers, -Jaakko (This reply will probably not get posted to crisismappers as I seem to have subscribed to it with another email address.)

Part of the project concerns establishing agro-forestry plots and sustainable fuel-wood forest and as part of this it would be very useful to get a detailed map of forest extent as it stands. More knowledgeable in GIS than in RS, I am aware that it is possible to use QGIS, with GRASS running in the background for image processing, but RS datasets I am more unsure. Initially I was intending to use LANDSAT imagery, but I am aware of the problems (in addition to low resolution) with Landsat 7 post 2003 with the SLC malfunction…. and for post-earthquake Haiti I am told that there is a lot of very high resolution imagery made freely available by DMCii, and GeoEye (IKONOS) also???...I am aware of the world bank funded (?) imagery available at IPLR – but this doesn’t cover the area I am after. Fairly new to this group, I have seen threads here before to request datasets/knowledge about datasets for various international projects and so thought I’d approach with the hope for a response about the best approach – either for advice about open-source/freely available RS data for this project and channels to access these.
