This weeks lab explored various methods of image preprocessing and band indices. The lab required us to utilize both ArcGIS Pro and Erdas Imagine to identify features in images via the implementation of various band combinations. We also were introduced to the NDVI function of Erdas Imagine and the utility of histograms in both programs. Using the various techniques learned throughout the lab, we were given spectral criteria for three features and tasked with identifying and presenting them. The resulting maps and there band combinations are depicted in the layout above. The label under each map states the feature that map accentuates.
