Spatial Enhancement, Multispectral Data, and Band Indices

 
This week's lab focused on my neck of the woods in the Pacific Northwest.  It was fun getting to learn about different spectral combinations to identify features in a region that I am very well acquainted with.

The focus this week was to learn how to use different processes to identify features in an image. Some of these processes included the use of histograms, image enhancement methods, and the use of spectral characteristics.

Introduction to ERDAS and Digital Data

This weeks lab had us focusing on using ERDAS Imagine. This was my first time using this software so, this lab was a little slow going at first. Especially since the lab instructions were clearly created using an older version of the software which resulted in a lot of "hunt and peck" on my end. However, once I got used to it, it became more intuitive. 

I appreciated the second half of the lab because it was focused on showing the functionality and utilization of tools in ERDAS. There are quite a few similarities to ArcGIS but overall, ERDAS is a little more user friendly.
