This was our first lab for GIS4035 Photo Interpretation and Remote Sensing. The lab consisted of three parts which were relatively simple and drawing on skills learned in our previous GIS5050 course. The first sections of the lab explored our ability to not only locate various items, textures, and tones on a map but also locate these items in regard to their association to other items, their pattern, and their shadow. The third component of this lab experience had us witness the color differential between true color images and false color images.
Our deliverables for the project were only required from the first two sections. Below are two maps which I created. The first map illustrates an aged aerial photograph where we had to create polygons identifying regions representing tone (color variance throughout the image) and texture (the population of various affects on the image which gave it a smooth or coarse 'texture'). The areas had to labelled qualifying their tone and texture from lightest/smoothest to darkest/coarsest.
In the second map, we were provided with an aerial image of a location in Pensacola, Florida. Without assistance, we had to plot points identifying various features on the photograph and how we deduced them. The first points simply cover view, meaning, I looked at the map and identified items I saw. The second was in regard to shadow. Using shadows cast by the various features, we had to identify features that would be difficult to either see or determine. Next, we used pattern. My selection ranged from repeating painted stripes for parking spots and repeating shadowed poles (light poles) evenly placed in front of a series of homes in a neighborhood. Lastly, we had to identify features by association. As you may have noticed, deducing some of these features may often pull from skills involving more than one of these strategies. With association, I deduced a pool (due to parking spaces, two identical buildings, and in a courtyard a pool with a diving board). I assume these buildings belonged to a hotel and in the center of their environment was a pool. Another example using association was cars. Since there were many similar boxes, associated in parking spots, in a line equidistant from a wall of a building, I assumed cars.
