Dear Mohammed,
there is a growing body of literature using the random forest method
(and the related bagging technique) in remote sensing, e.g.:
Pal (2005) in Int. J. Remote Sensing
Lawrence et al. (2006) in Remote Sensing of Environment
Brenning (2009) in Remote Sensing of Environment
Knudby et al. (2010) in Remote Sensing of Environment
(see also references cited by these articles)
Random forests in R can be applied to rasters using several packages
including RSAGA and raster. The RSAGA approach is outlined in this article:
http://www.environment.uwaterloo.ca/u/brenning/Brenning-2008-RSAGA.pdf
(Small update: use the new and more efficient 'local.function' instead
of 'multi.local.function' in RSAGA. Note that these functions do not
require SAGA GIS to be installed.)
I hope this helps getting you started...
Best,
Alex

Hi All, I wrant to do Random Forest classification. I installed R,
randomForest classifier package for R but dont know how to use it.
Is there any Open Source Remote sensing application which do RF
classification on satellite images?
Anyone r has random forest classification example?
Any language or package example no problem.
Does anyone did it in R? if yes how?
I google RF Classification but most of them are for medical disease
and research not for Remote Sensing -- Regards, Mohammed Rashad K M
