Mod 2.1: DEM and TINs

 This week, we explored the applications and used for DEM ( Digital Elevation Models) and TINs ( Triangulated Irregular Networks). They are often used for imagery and elevation models but learning more in-depth about their advantages and disadvantages to showcase data. 

TINs are not generalize compared to DEMs and can showcase more data with higher densities of data. TIN can form more accurate contour lines based on the terrain. TINs generate vector points from x,y, and z coordinates and then bind the three points creating the triangles which can form the triangulated patterned model. 

DEMs on the other hand create smoother and rounded contour lines. DEMs oftentimes in projects are used to create a grayscale gradient of elevation and simple elevation models in the 3D application of Arc Pro. DEM has limitations in its presentation and since it generalizes its models it has the possibility to misses terrain factors such as hills and dipped along a mountainside.

Fundamentals in Python

  Flowchart Working with Spyder was a challenge. I had started on step 1 on a different approach than the lab instructions gave. My First Attempt started as follows stringName = “Brittany Anne Joe”  nameList – (“Brittany” “Anne” “Joe”)  print (“Joe”)  Although this gave the same results of printing my last name Joe in the program I learned to use some of Python’s functions that allows me to print my last name from a list. stringName.split automatically takes your stringName feature and divide it into separate cars for “Brittany” “Anne” “Joe”. To specify what to print from a list you need to index by specifying the number that represents your list. So “Brittany” would be 0, “Anne “would be 1, and “Joe” was 2.  After step 1, we had to debug a prewritten code that generates the results of random wins and losses for the players. I was challenged to create a loop to generate 20 random numbers between 0-10. My unlucky value was number 5 and we had to use an if/else statement to count the num

Module 5: Choropleth and Proportional Mapping

Image
 This week's assignment challenges us to explore data sets and using graduated and proportional symbology to present data. Graduated symbology utilizes classified data that shows the quantitative differences between data in which data is classified in ranges and a different sized symbol represents that range. Proportional symbology uses unclassified data to represent values in a field using the attribute value.  One challenge in this week's lab was working on the symbology by inputting a picture symbol into the mapping project. Another challenge to the week's lab is adjusting the European country's labels. Due to the close proximity of some countries or the size of the country the label wouldn't fit inside. Many adjustments were made, but there can be further improvements in future projects.

Module 3: Cartographic Design

Image
 Gestalt's Principles   In our week's lesson, we learned about Gestalt's Principles covers cartographic design techniques that allows the audience to better understand a map. Few points about cartographic design and how gestalt's principles apply to map design is understanding the four techniques to display data.  Visual Heirachy Using symbols and ranking methodology to highlight data importance or where you want your audience to focus on in map. You can make single symbols different sizes to represent different classes or highlight their value on the map compared to other data such as population maps.  Contrast  Contrast focuses on differences between map features such as adjustments to size, color, or shape. Sometimes certain color choices such as blues and reds are great for highway and interstates. It can be helpful with a neutral background.  Balance  Balance is the organization of all map elements that fills the space granted for the map project, but use empty spa
