cvamko Posted October 29, 2012 Report Share Posted October 29, 2012 Hello everybody! I am trying to make a relatively simple LULC classification of a region with only 5 categories - grassland, agricultural, built-up, forest and other. I have the data for summer seasons. I tried with several RGB combinations, PCA, band ratios from every possible tutorial, still I can't differentiate barren land (in this case "agricultural" category") and built-up. Is there any algorithm or some procedure which would select some of the possible good combinations? I am working with ArcGIS 9.3 and am very frustrated. Also, when I tried with several procedures, I did it parallel on 1991 and 2011 datasets, LANDSAT same bands and same month of the year, unsupervised classification, I got completely different results, some classes were impossible to distinguish on one dataset, and were separated in the other. Thank you in advance. Quote Link to comment Share on other sites More sharing options...
SIGIS Posted October 29, 2012 Report Share Posted October 29, 2012 Hi you are using a tool which doesn't you have a landsat dataset why don't using a remote sensing tool such as ENVI ? If you know C or C++ language you can also use the Orfeo Toolbox which is a beautiful library mixing topology and remote sensing. Quote Link to comment Share on other sites More sharing options...
