Module 4: Spatial Enhancement, Multispectral Data, and Band Indices

Module 4 we learned how to download and import satellite imagery, explore and interpret histogram data, identify features using that data, and create spectral band indices. 

I used the grayscale layers to find the first two features by using the histogram in the metadata and inquire on the maps. I then used the band combinations from the Lab Exercises. 

The first feature in Layer 4 was Puget Sound. From the spike I knew it was a dark color and inquired all the relevant areas on the map till I found the one that matched. 

The second feature the represents both small and large spikes is Mount Olympus, after looking at the histograms I knew that the area would be dark and bright so I inquired the Mountain area first and it matched.

The third feature I opened in True color since I knew I would be looking for variations in water and found those variations in the North Bay area.
