Hello, Ive been using the Iso Cluster Unsupervised Classification tool in the Image Classification toolbar released in ArcGIS 10.
Ive been using it to process some CIR aerial photographs. It has been fine so far but however for seem reason today i seems to be acting funny and im not sure why.
I've been breaking down a series of images into 4 classes in each tile.
Today however either though I've been specifying 4 classes sometimes the tiles are only returning 2 or 3 classes.
Any idea why this is? Im not sure if its a bug within arc or theres something different with those tiles and the other tiles.
