Module 3 - Ward 7

-

Module 3 assignment for the Cartography class was to create a map showing the location of Public Schools in Ward 7, Washington D.C. The assignment focused on the utilization of Gestalt’s Principles of Visual Hierarchy, Figure-ground distinction, Contrast, and balance. The map needed to contain a frame that focused on the Ward 7 area and an inset frame that showed the location of Ward 7 within the Washington D.C. area.

ArcGIS Pro was used to create the map using provided data from District of Columbia Open data. A Geodatabase was provided that included a point feature class of all the Public Schools in Washington D.C., the Ward 7 and Washington D.C. boundaries, parks and surface water, and different levels of transportation layers.

Visual hierarchy was implemented on the map by using symbology that brings the school locations to the forefront of the map. The reddish hue of the school’s symbols makes them stand out as the most important feature on the map. The reader is then directed to the Ward 7 study area and then to the other elements of the map.

The figure-ground relationship on both the main map and the location map was established by using a lighter color for the foreground area and a darker color for the background. Ward 7 area uses a lighter green color, and the Washington DC area has a darker version of the same green hue. The Ward 7 area is perceived to be in the foreground and the Washing DC area in the background.

The map was balanced on the page by placing Ward 7 at the visual center of the map at a reasonable scale to allow it to be as large as possible. The shape of Ward 7 allows for several open spaces to fit the location inset map and the other map elements to provide a balanced layout.

GIS Programming Module 1 – Python Environments & Flowcharts

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 Programming Module 2 – Python Fundamentals

Image
  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 ...

GIS 5935 Lab 1 - Calculating Metrics for Spatial Data Quality

-
Image
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. Image Source: https://byjus.com/physics/accuracy-precision-measurement/ The map below shows red dots for waypoints that were captured using an unknown GPS device. These 50 waypoints were captured using the same GPS and at the same location. The points should be at the sam...
