Python Module 1 Recap: From Scripts to Flowcharts and Zen Principles

Converting 3 Radians to Degrees

To convert 3 radians to degrees, we use a simple formula: degrees = radians * 180 / pi

Below is the flowchart illustrating the conversion process:



Running the calculations in IDLE gives us: ≈171.887


Interpretation of the Zen of Python

The "Zen of Python" showcases the philosophy and guiding principles of Python programming. It emphasizes simplicity, readability, and clarity in code. In other words, “Zen of Python” promotes straightforward and elegant solutions over complicated ones. By valuing explicitness over implicitness, the basis of Python encourages clear and understandable code. Moreover, The principles highlight the importance of practicality and avoiding unnecessary complexity— why use 4 lines of code when 1 will do the same thing? This mentality helps to balance between purity and practicality. Overall, the “Zen of Python” advocates for writing code that is easy to understand, maintain, and edit.

Process Summary

Data

  • Sources: R:/GISProgramming/Module1
  • Steps:
    1. Created directories using IDLE and the provided Python script within S:\ drive.
    2. Developed a flowchart to convert radians to degrees.
    3. Wrote and tested the Python script for conversion.
    4. Summarized the process and answered module questions.

Experience

  • Initially, creating flowcharts seemed a bit confusing due to specific shapes indicating specific functions, but there's diagrams with Google that help. 
  • Running scripts in IDLE was different than ArcGIS, especially since ArcGIS 

Notes

  • IDLE and Jupyter Notebooks serve different purposes. IDLE is lightweight and ideal for simple scripts, while Jupyter Notebooks looks like it has a more interactive environment suited for data analysis and visualization.
  • Python's nature as an interpreted language means the code is executed line by line.

GIS Map Projections

Image
  This week's lab exercise looked at the importance of map projections in GIS, especially when using multiple datasets. The map above shows four counties in Florida that are displayed using the Albers Conical Equal Area, NAD 1983 UTM Zone 16N, and NAD 1983 HARN State Plane Florida North FIPS 0903 (US Feet) map projections. As the table within the map shows, the areas of the counties vary depending on the map projections. The best map projections are ones that shows the least distortion between map features. For example, The UTM projection is best when used the map features fit within one UTM zone, which is not the case for showing the entire state of Florida. The same can be said for the Florida State Plane that is dependent on the region of interest. Therefore, the map projection would need to be Albers since it minimizes distortion between its standard parallels.  Overall, this lab illustrates how important it is to use accurate map projections since it can cause distortions betw

ArcGIS Pro Orientation

  Module 1 Lab Assignment This first lab assignment's objective is to prepare and show what is expected for future lab assignments. The primary learning outcomes involved: Getting familiar with accessing the ArcGIS software through Argo Apps. Assessing data storage drives. Preparing project folders for each project. The map shown above is a visualization of the Cities and World Countries data files found in the OverviewArcGIS file in the R drive. In order to view the shapefiles in a way that is informative, we had to add a Folder Connection to the data we downloaded as well as update the symbology to show graduated colors for the field POP_2007 with Natural Breaks and 7 classes. It is important to use a single color from light to dark when using sequential data. While I wish this had been a smooth and uncomplicated process, I struggled with learning UWF's Argo Apps since that is how we access ArcGIS Pro without downloading it to our personal computers. While I am familiar with
