Hi guys,

Let me preface my question by saying that I have very little experience with ArcGIS. Most of what I know, I've had to learn through articles on the web as well as the support here on ESRI's website. With that said, I am trying to combine classes after just running an ISODATA Cluster Unsupervised Classification. My final product needs to have around 5-10 classes. From what I have read, I am going to need to use the Swipe, Flicker and Identify tools to discover agreement (or disagreement) between points falling in the same class. I understand how the Identify tool works but how do the other two work and how should I use them to help me recombine classes? Also, how should I be using the Reclassify tool?

One more question, when I run the ISODATA Cluster Unsupervised Classification, I ask for 16 classes yet it only gives me 3-4. Why does it do this? How can I get more classes?

ANY help would be GREATLY appreciated! Thanks guys and sorry for my noobiness.
