Hi All :) I've a problem using ENVI that I hope you can help me to solve. How can I use a 1000 points shapefile for classification within ENVI without dissolving those points by attribute to obtain 8 ROI's (1 per land cover category)? I've worked with a dissolved shapefile but I've been told me that using a dissolved shapefile I would affect the results of classification because the classifier would only use the average ND value of each dissolved category, and not each pixel as I want. Any suggestions? Thanks in advance! AG
