Lab 4: Remote Sensing of the Environment
Introduction: The purpose of this lab is to further familiarize students with ERDAS photo analysis capabilities, including image pre-processing, stitching, and optimizing. In the following exercise, students will execute a series of several new capabilities: 1. Image Subsetting 2. Image Fusion 3. Radiometric Enhancement 4. Syncing Image Viewer with Google Earth 5. Resampling 6. Image Mosaicking, and 7. Binary Change Detection (or Image Differencing) Methods & Results: Part One: Image Subsetting of a Study Area- There are two different methods that can be used for subsetting satellite images: 1. The use of an Inquiry Box 2. Delineating an area of interest (AOI) with the use of a shapefile Figure 1: Inquiry Box Method of Image Subsetting The each method can be easily execute...
