  Boy oh Boy! Well, this Lab ended up taking a very negative turn for me. Before I explain how I failed in this module I will explain the lab. For module 5 we learned how to use supervised and unsupervised classification. This allows the user to better classify features in an image to create a more detail. One way this is helpful is it allows you to merge objects that have similar content into one single feature. The image you see above is not even close to what was required for this Lab. This is actually the perfect example of what a bad layout for this project looks like. What happened is I created an image prior to this one that was a lot more detailed and significantly closer to what was asked for. The problem I ran into was that the water features were not coming in the way I wanted them to. So, in order to make the map more aesthetically pleasing I decided to go back and try and make some edits. I messed up when I overwrote the previous image, I ended up with an image along w...

  Lab 4 was undoubtedly the most challenging lab thus far for me. Not because it was hard but mainly due to the large amount of information in this lab. Despite the challenges I did find this lab to be interesting. There were quite a few deliverables in this lab, and it also required students to jump back and forth between Arc Pro and ERDAS quite a bit. All the work on this lab resulted in the layout you see above. Essentially what you see is a layout showing 3 separate images all using a different set of bands and focusing on different objects. Students were instructed to use the histogram and analyze spikes to determine certain features on the map.       

   In lab 3 we did an introduction to an application called ERDAS. In the introduction we did an overview of the application and its capabilities. While reviewing the application we created a small map and added the area of each individual attribute in hectares. Overall, this was a good lab. I did run into a few issues along the way but after going back and checking my work and even redoing sections I was able to get exactly what I needed done.
