Module 1 Photo Interpretation and Remote Sensing: Visual Interpretation

     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. 

    Exercise 2 had me make a map to identify features on an aerial photo using a few different criteria. Features on the map are selected based on which feature makes them identifiable, e.g. the waves in the water are identifiable because of the pattern of waves in the photo. Association, pattern, shadow, and shape/size were used. Shadows were the toughest one and I finished them last but the others were not too difficult to find. 

Thank you,
Joel Sexson

Module 2 GIS Programming: Python Fundamentals

Image
      Hello all, the second week of GIS Programming (4102/5103) was focused on learning the fundamentals of Python. This included topics such as loops, formatting, lists, sets, and many other basic functions/methods used in Python scripting. As I've said before, the Zandbergen (2020) book helped a lot with figuring out how to do a lot of this. This week we were tasked first with creating a set of names and splitting it into a list. This was simple enough and was a good introduction to creating and indexing a list. The harder parts of the assignment were correcting the dice code and creating a randomly generated list using a while loop.  I've provided my results from the code down below:     The dice code had two errors, which took me longer than I expected to figure out. The first error was a syntax mistake in a print code that needed to be cast. The second error was simply a capitalized X instead of a lowercase x. I have included a flowchart of the logic b...

Module 5 GIS Programming: Explore and Manipulate Data

Image
 Hello all, in the 5th week of GIS Programming we learned how to deal with data. As the title of the module states, we explored data using things like describe functions and search cursors, and we manipulated data by learning about insert/update cursors and how to create different data (such as creating a file geodatabase or a dictionary).      The assignment was to create a script that made a new file geodatabase, copied over feature classes from one folder to the geodatabase, and then populated a dictionary using data from a search cursor done on the cities layer in the fGDB.      Below is a picture of the flowchart of my script:       The results of the script are shown above. There are print statements throughout the script to explain what processes were happening and when they were completed. The only problem that I ran into with the script actually helped me learn how to determine if my script is working the way I want it to i...

Module 6 GIS Programming: Working with Geometries

Image
 Hello all, in the final week of GIS Programming we learned how to work with geometric data from ArcGIS in Python. This included each level of geometric data, from features and arrays down to just point and coordinate data. We also practiced writing data to a text file and using the nested for loops to reach different levels of data. The getPart method was used in particular to skip a loop and retrieve the coordinate data for the rivers.  I've included a small text file section where I printed the OID, vertex ID, x,y coordinates, and the feature's name (from left to right).      The assignment was very logical and did not create too many problems for me. I need to remember to close the text file at the end so that the processes will actually occur and write to the text file. I've included a flowchart of the logic of my script below: Thank you,     Joel Sexson
