satellite imagery
Hi Nick, The Raster package has been my key to working with images in R. Leveraging the Raster package you can use just about any classification engine or statistics queries you want. I've been quite impress with the RandomForest package (among others) for image classification. I'm happy to share the script I use and a guide with instructions if you're interested. All the best, Ned

Hi all, I would like to do some somewhat simple satellite image analysis, ideally with an R package. Basically, I need to: * load a .img file (a subset of a 6-channel Landsat image) * classify the pixels * extract some statistics Is there an R package people would recommend for this kind of thing? I'm working with macs, basically, I know some of the free GIS stuff is windows-based... Any advice appreciated. Cheers! Nick
