GIS Programming Module 2 – Python Fundamentals

-

 

Module 2 assignment covered some of the fundamentals of Python. This included learning about the different Python data types, working with string variables, understanding loops and conditional statements, and iterating through variables.

 The screenshot below shows the output of the script written for the assignment.


Step 1 was to create a variable to hold my full name separated by spaces, split the variable using the spaces, and then print my last name using the index -1. The index -1 is the last item in the list which was my last name.

Step 2 was to fix two errors in the code that was provided. The code uses a list of the first names of players and calculates the number of characters in players’ name. Each player rolls a dice which is randomly selected from a list of integers from 0 to 2 times the number of characters in the name. Players win if the dice is greater than the number of characters, tie if they are equal, and lose if the dice is less than the number of characters.

The first error in the code was the print statement that tried to concatenate an integer. To fix the issues, the dice variable needed to be cast into a string using str(dice).

The second issue was due to Python being case sensitive. The X in the if statement was uppercase and needed to be lower case to match all the other x variable references.

Step 3 was to randomly create a list of 20 integers that had values between 0 and 10. The list needed to be created using a while loop and if statement to track the number of numbers added to the list. The last part was to print the list of 20 random numbers.

Step 4 was to choose an unlucky number, count the number of times the number appeared in the list from step 3, and then print the number times it would be removed. The last part was to remove the unlucky number from the list and print the updated list.

Flowchart for all the steps.

Module 1 examines “The Zen of Python” which is a poem by Tim Peters a software engineer. This poem can be seen by typing “import this” into any Python interpreter and describes what it means to write Python code. “The Zen of Python” is the principals or guidelines on how programmers should write code. These principles suggest to me that we should write code in a way that is easy to read and understand, even though the code may be complicated. I see this as writing code that is modular where the complexity can be broken down into smaller functions that do a specific task. Complexity can also be handled by simplifying the code, by finding ways to reduce the number of lines it takes to accomplish the same task. We should follow these principles not only for others who might later need to interpret the code, but for ourselves to help us in debugging and future alterations. It is up to the programmer to write code that provides the required functionality, but they should make a conscious ef

GIS 5935 Lab 1 - Calculating Metrics for Spatial Data Quality

The first lab of GIS 5939 concerned spatial data quality and being able to determine if the data is accurate, precise, or has any bias. This involved understanding the difference between accuracy and precision. The horizontal accuracy of a point is determined by how close the collected points are from the true location. This is calculated by measuring the distance from the average of all points collected and the reference point. The larger the distance means, the lower the accuracy. The horizontal precision is how close different measurements are from each other. Points that are clustered together have high precision and points that are spread-out have low precision. The image below illustrates accuracy and precision.

These 50 waypoints were captured using the same GPS and at the same location. The points should be at the sam
