Hi, If you are willing to program with java, you could also base yourself on Nasa's open-source dev kit: [hide] http://worldwind.arc.nasa.gov/java/ [/hide] Help is provided too: [hide] http://worldwindcentral.com/wiki/Java [/hide]

Hi 3dbu, Thanks for the different ideas. I have to say though: due to my expertise in geomorphology I would like to keep working on the assessment of landslides to protect inhabited areas. I have a feeling I could use land-change analysis to detect structural changes in the land. The challenge will be to take in account these deformations with only optical data. I'm also looking into rain thresholds that can trigger movements. Anyone got advice on this more precise direction?

Hello there, Knowing the power of thoughts developed in communities, I thought I would ask around here for a few tips. I am actually a student in the first year of Master degree (in France - pardon my English) in geography and geomatics. Being in a research course I have to find a subject to develop over the two years. Having followed courses in geomorphology I had started to work on the use of SAR imagery coupled with static ground (ie GPS) measures for an earlier detection of landslides. Unfortunately, after a few months of discussion with my director and vain waiting - the sentence fell: I won't get the funds to purchase the needed imagery. If I want pictures, I will have to buy them or get them free (I can't afford the few thousand dollars cost of SAR data sets). I can use the GPS technology of the university but will probably have to beg for that! This means I have to turn the subject around and find an other approach for my thesis. I am getting back into my lectures and research to bring up new ideas. I was wondering if anyone here works in that field of analysis or has any tips to orientate me. Not looking for people to do my work here, but I am convinced that speaking with different people can bring up new ideas. So don't hesitate to drop in a line! :wink: Thanks,

Thanks for your help, I've managed at last after a lot of boxes in the macromodeller Here is my result:

Hi, Thanks for this first bit of advice. You have understood my two questions very well (good comprehension between two non-English natives!). I will try an overlay (addition) in my macromodeller. However I don't understand the bit about "weight score" affecting the variable. I will try searching around for more information about that. As for my second question, I was hoping (probably foolishly) that the program could make a vector file with 130 sq meter squares on top of my final raster. Finally I have done an "area" function to a text file and divided the results by 130 (explained in my written analysis). By plot I meant the number of plots of land that could be used for residential use. Can you try and tell me more about the weight score if that is not asking too much? Thanks, Max

Hello all, Being a student in GIS, I have yet a lot to learn. I actually have to give in a report for my class, but there are two things I would like to do, that I am stuck on. I am working on IDRISI Taïga. I have decided to map the natural risks of a town situated in a valley in order to find the places where the town can expand. I have now a map with the existing urbanized areas, the flood zones (where it is forbidden to build), the avalanche zones, the slopes under x% (from a DEM I made) and the roads (less than x meters from them - Buffer function). I am now left with zones that can potentially be urbanized. First question: I have also mapped the forests: is it possible to favor the bare lands over the forests, and create a new class involving a cost factor? I would like to end up with a category of land that can be built for a certain price, and a second category that can be built but with a higher price because of the deforestation needed. Second question: in the town planning documents, it is said that the minimum size for a plot is 130 sq meters. Is it possible to have the program calculate the maximum number of plots that can be implanted? If for example there is a piece of constructible land 1300sq meters, can I have the program to draw 10 plots on that area? I hope I have been clear enough, pardon me for the mistakes as I am a "foreigner" :smiley: I hope you can bring me a bit more knowledge in a discipline I love so much. Max

Hello forum, I am a student in third year of Geography, in France. I have started doing GIS since last year, and absolutely love it. Next year I will be doing an exchange year in Canada. After that I am hoping to do research and maybe carry on to integrate a lab at university. This forum brought me a lot of information so I decided to thank you for that and present myself. Max
