 For Lab 4, Spatial Enhancement, we looked into learning how to work with Landsat 4-5 data form the official Glovis website and use ERDAS and ArcGIS Pro to run spatial enhancement tools on different image. The first and second exercise involved learning how to download and format data from the Glovis website. The third exercise involves using and manipulating image histograms for the LandSat data. The fourth and fifth exercise includes the use of Spatial Characteristics and Band Ratios to alter the band layers to make certain features pop out more than others. The sixth exercise involved examining the layer information of the image layers while the seventh exercise involved tying in all the exercises to now independently identify features with what was learned. Below shows 3 different maps showing a large river, lake, and snow cover features identified with spatial enhancement.

 Hello everyone, for lab 3 of Photo Interpretation and Remote Sensing with took a look into  Earth Resources Data Analysis System  or ERDAS and navigated through different tools and applications. This lab was broken up into 2 parts and served as a first look as I was introduced to the functionality of ERDAS which I have not done before. I also had time to play with the viewing aspects, data manipulation, shortcuts, and also creating a subset to make a map. The first part dealt with the basic and map making while the second part dived into examining remote sensing properties such as Spatial resolution, radiometric resolution, Temporal and Spectral resolution, etc. The map below shows the creation of a subset I made on ERDAS that was transferred to ArcGIS Pro to create a map.
