Question

1. Based on your visual examination of the multiple ISODATA-classified images that you generated (and their relation to the original Landsat TM image), discuss the effect of utilizing varying ISODATA parameter values on the resultant classified images. Visually, are there any conclusions/recommendations that you can draw from these results in terms of what parameter settings may be advantageous to utilize in terms of improving classification accuracy?

2. Based on your visual examination of the multiple maximum likelihood classification images (and their relation to the original Landsat TM image), discuss the effect of varying the probability threshold value setting. Visually, are there any conclusions/recommendations that you can draw from these results in terms of what threshold settings may be advantageous to utilize? How did the classification change when you added a new training area?

Explanation / Answer

2) I can classify whole image according to colour . And i can assign different class to different colour because they will show different DEM value .
