M4 - Spatial Enhancements, Multispectral Data and Band Indices

 

Feature Identification Using Spatial Enhancement Techniques
I am becoming very confident in my GIS abilities and am much more comfortable with ERDAS Imagine software after this assignment. It was very enjoyable learning how to identify features within ERDAS and I will certainly use the techniques learned in this lab in future assignments. The histogram was crucial to my understanding of pixel values and what they mean. Utilizing grayscale/panchromatic images allowed me to notice trends that I would not otherwise see. I found that altering the band combinations allowed me to distinguish features from their surroundings, and I enjoyed changing these combinations to best suit the purposes of my final map layout. For my final layout, I decided to get creative and utilize a series of lines and polygons to create more unique subset maps that would showcase the features in a larger view. This final map I am very proud of and I enjoyed making it every step of the way.
