Photo Interpretation and Remote Sensing 

This week in class we learned about the different factors that could interfere with Electromagnetic Radiation (EMR) that is used for remote sensing. We also learned about and practiced some techniques to correct and enhance imagery. We added filters and manipulated bands in spectral imagery in both ERDAS Imagine and ArcPro. 

As part of our lab assignment we had to identify different features in a multispectral image that was provided. We used various techniques in ERDAS Imagine to identify certain features. Techniques we used to identify features included: visual examination of grayscale images, image histogram interpretation, visual examination of multispectral imagery (with varied band combinations) and the Inquire cursor. Identifying features ranged in difficulty as sometimes examining and interpreting an images histogram would give away a feature but in some occasions the spectral imager had to be closely examined to find the feature in question. Below is the map I created showing the features that I found for this lab assignment.
