moawad74 Posted March 4, 2014 Report Share Posted March 4, 2014 (edited) Geological formation (vertical column) Surfacial deposits Structure (rock tension i.e. joints, faults, fractures..etc) Slopes Historical records to estimate probability of occurrence If it is possible you have to measure what is known as safety index.... if you could determine it, it would be enough because it includes all the above factors Have fun Edited March 4, 2014 by moawad74 Quote Link to comment Share on other sites More sharing options...
terefice Posted March 4, 2014 Author Report Share Posted March 4, 2014 that sounds great but how can identify them to ecognation software Quote Link to comment Share on other sites More sharing options...
Arhanghelul Posted March 4, 2014 Report Share Posted March 4, 2014 First, depends on what type of data you are using in your analysis. Is it satellite/airborne images (what spatial/spectral resolutions ? ) or is it radar SAR ? Then, you must make yourself a good documentation, see what other researchers used, what methodology to apply and what results to expect. There is no universal rule set to apply, you must develop your own personal rule-set adapted to your data type and your study objectifs. You can try to search some informations on eCognition community. Quote Link to comment Share on other sites More sharing options...
terefice Posted March 4, 2014 Author Report Share Posted March 4, 2014 thanks i use spot 5 data for two time period Quote Link to comment Share on other sites More sharing options...
moawad74 Posted March 6, 2014 Report Share Posted March 6, 2014 Well, I am not such professional in eCognition but it sounds to me that you need a complex spatial model with conditional statements to detect vulnerable areas based on the data layers I mentioned before... If you can measure the safety index, this will be enough to be classified in any software as well as eCognition and define vulnerable sites... 1 Quote Link to comment Share on other sites More sharing options...
