Module 2: LiDAR

 

In Module 2 we covered the use of LiDAR in ArcGIS Pro. Some of this module served as a refresher from a previous class in the certificate course called remote sensing. This lab gave me a much better understanding of how elevation data is used in forest analysis. The main goal was to process a LAS file to create a Digital Elevation Model (DEM), Digital Surface Model (DSM), and a Canopy Height Model (CHM). Once the CHM was built, I created a 3D view to visualize tree canopy density across the landscape.

What stood out most was seeing how LiDAR data can clearly show the height of trees and other features compared to the bare earth surface. The 3D model included things like roads, rivers, and dense forest areas, with visible buildings.

This was a enjoyable lab for several different reasons but primarily due to the 3D aspect. It was also helpful seeing a practical use for LiDAR in this setting. I hope to use it more as this class progresses.

Module 6: Isarithmic Mapping

Image
  In module 6 we focused on Isarithmic mapping. Isarithmic mapping uses lines (isolines) to link points of equal value for continuous data like temperature or rainfall across a map. The pattern and spacing of these lines visually represent the distribution and rate of change of the phenomenon.  The lab for module 6 was quite interesting. We used data from PRISM to complete this lab. PRISM is a group out of Oregon State University that generates detailed maps of monthly and annual climate conditions like precipitation and temperature. It works by combining specific data points with a base grid, such as elevation data or a 30-year climate average. This approach is very effective in mountainous areas because it accounts for how terrain influences weather patterns. Monthly maps are created first, and then annual temperature maps are derived by averaging these monthly values, while annual precipitation maps are calculated by adding the monthly totals. As you can see when viewi...

Final Project Bobwhite-Manatee Transmission Line

Image
Wow! I do not even know where to begin. This has by far been the most stressful and intensive school project I have ever had to complete. I have worked on this project from 7:00 pm to after 1:00am every weekday this week. Aside from sleep deprivation making this project challenging I also struggled greatly due to the lack of instruction. While I understand that aspect of the assignment these kinds of projects become very challenging for me because I over think the process and end up having a symptom some call "paralysis by analysis." Despite those struggles I pressed through and came out with a halfway decent result. I do wish I had more time on this project to clarify some things and make my data more readable, also due to time constraints there were several things I was no able to compete but for the time being I think my results will be acceptable.  I will give a brief overview of the final project. I only attached two of the maps I created because if I were to add them al...

Module 4: Data Classification

Image
This lab session was about understanding data classification. The lecture explained different types of data and how they're shown on maps. It then covered various methods for dividing data into categories for visual representation. In the Lab portion, we used census data for Miami-Dade County, Florida, specifically looking at the percentage of the population over 65. We created four different maps of this same information, with each map using a different data classification method. Those classifications were Equal Interval, Quantile, Standard Deviation, and Natural Breaks. We then arranged these four maps on a single layout, including standard map elements. The goal was to visually compare how each classification method displayed the data and what patterns became apparent or less obvious with each approach. Finally, we considered which classification method might be most useful for different purposes, such as identifying areas with a high senior population, and whether using percen...
