Joel Sexson's GIS Blog UWF

 Hello all, in module 2 of my PI&RS course, we practiced land use/land classification (LULC) on a photo. We also got practice with digitally truthing to test out the accuracy of our classifications.  I have included the map from the exercise below. The map shows the LULC in slightly transparent colors and the accuracy of the random points. The legend gives a brief description of each type of LULC code. This exercise was useful in learning how to use some interpretation skills that I learned from the previous model on classifying areas within a photo.  Thank you, Joel Sexson

      Hello all, in the first module of my PI&RS course, we practiced three different methods of visual interpretation. We used aerial photos and practiced identifying features based on tone, texture, shadows, shape/size, association, and patterns. We also compared a true-color image to its false-color counterpart to understand the contrast between how colors are displayed between the two methods.      I have included the map layouts of my visual interpretations from Exercises 1 and 2, but not the map from Exercise 3 which involved the color method comparisons.      The first map depicts the interpretation of different levels of tone and texture on an aerial photo. The tone ranged from very dark to very light and the texture ranged from very fine to very coarse. The texture was easier to determine than the tone which caused the tone portion of the exercise to take longer; however, I was able to complete it fully in the end.    ...
