This week’s been fraught with problems for the forestry component of the project so it has been difficult to put together a comprehensive plan about where we are going with REDD until today.

We’ll be doing another forest inventory of a region very near to the last one.  So, first of all, I will try to update the forest map as best I can with satellite images and field visits so that when we place the measurement points we don’t end up in the middle of coffee plantations.  Like last time.  I’m then going to put together a short questionnaire for the M’Nong villagers who help with the inventory, with questions about them and their lives.  Those data, along with some nice profile shots, will be a great addition to the map data once it is online; it will show that we really got to know the local people and put faces to the issues in the area.  These will, of course, be incorporated into Google Earth as balloons so they’ll pop up in context as people are using the site.

Getting a hold of good satellite imagery is turning out to be a bit of a problem but at this planning stage it might be enough to use LANDSAT images although a) the resolution is a bit weak and b) the recent images have these annoying blank lines through them because of a fault on the satellite itself in 2003.  We’ll make do, of course, but will be begging the people from the Japanese International Cooperation Agency who are here next week to lend us theirs…

GPS and ESRI

with one comment

Why is it that the world’s leading GIS software company make it so much less than simple to import rich GPS data?  Having spent much of the morning tracking down a nice program that works we can now see some of the additional points we made splayed out on the map.  The rest is joining the dots.

These extra points are largely Christian’s attempt to find the boundary of the region of forest, normally a prerequisite for forestry itinerary planning, but in our case the forest is so scattered and the undergrowth so thick that hacking through that enormous perimeter would take weeks and weeks of expensive time.

Having those GPS data in place I spent the afternoon testing classes in MultiSpecCarb so that when we have good satellite images, the processing will be a breeze…
