Orfeo ToolBox (OTB) is an amazing tool for remote sensing. Some modules are not included in the distribution because they are produced by external users, but some of them are really interesting.
R is a great tool for statistics, even if it may be slow in calculing raster’stats, it is really a good way for batching all of your work and presenting your data using MarkDown language. This example is one of my first autonomous script in R, and it is very exciting for further. You can download the whole script SPOT5-GetROIvalues.R on GitHub.
Before showing you the different steps of the code, I need to present you the way I structured my data, because the script is going to parse them and to compile all tables in one file.
I just published the plugin dzetsaka : classification tool (github/qgis) on Qgis plugin server. This is a very simple plugin to make a fast but powerful classification. I used it for making numerous classifications of SPOT 5 scenes in the French Guiana Amazon forest.
A project with samples (an old map (map.tif) and ROI (train.shp)) is available on the docs branch. You can download these files directly here.
