GIS4035 Lab 8: Thermal & Multispectral Analysis

For this weeks lab, we first created multispectral images by combining several layers into one image. This was done in both ArcMap and ERDAS. Then, we were to take one of the new images, identify a feature on it, and create a map showing that feature using the best band combination to make it stand out.

This was the map I made. I chose to identify the two bridges that crossed the river at both forks. I used a Red-3, Green-5, and Blue-6 band combination to make them stand out the best, being that the river had low temperature and low near-infrared, while the bridges had higher temperatures and low near-infrared.
