Module 5: Unsupervised & Supervised Classification

Module 5: Unsupervised & Supervised Classification

Module 5 covered Classification of Images in ERDAS, Collecting, Evaluating Spectral Signatures, and Unsupervised and Supervised Classification of Images 

For Exercise 1 I tried several times and different ways to recode to get rid of the unclassified and could not in ERDAS. 

In Exercise 2 I also could not get Unclassified to recode in ERDAS but was able to reclassify it out in ArcPro. 

I spent an embarrassing amount of time trying to figure out why my color boxes disappeared from my attribute table, which turned out to be a problem with the CITRIX view. Once I unmaximized the window, I could suddenly see the whole box. Since this has been an issue before, it should have occurred to me sooner. 

I also did not notice the very large and probably incorrect acreage on the Roads until it was a bit too late to turn back.
