--- Start of Idrisi List message I have a mask I am using to query layers to extract data for statistical analysis of variance. My problem is the autocorrelation is approx. .97 for the raster images. When I contract by a factor of 10 the autocorr drops to about .6, but I am having problems trying to figure out how to extract every 10th point to match the improved autocorr score. Any suggestions on sampling methods? --- End of Idrisi List message IDRISI-L is an unmoderated list. As a service to list users, please post a summary of useful responses to your questions.
