GIS 4035 Lab 2 LULC, Ground Truthing & Accuracy Assessment


 For this lab we took a look at an arial image of Pascagoula Mississippi. From the arial we drew polygons on all areas and labeled them the classification we thought they would be. Once we classified all areas of the arial we used a method called Ground Truthing to test the validity of our classifications. Ground Truthing in this assignment consisted of us using google maps to look at a street view image to determine if our classification was correct. I found this assignment to be enjoyable and I look forward to the next.

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...

W01 Overview of ArcGIS - Orientation Lab (1)

Image
 In the first lab we were given an overview of ArcGIS Pro and some of its basic functions. In the overview we covered the layout of ArcGIS Pro. We also learned how to upload data by making file connections and then how to navigate through that data once it is in the active view. We then interacted with the software by making a map. In the map we added a base map and then added colored layers for different countries and big black dots for major cities throughout the world. I will say that this lab really showed me how important file management is when it comes to this software. I was confused at times when creating fodders and adding data to them. I ended up making the mistake of labeling a folder wrongly. Once I figured this out, I was already mostly done with the lab, so I just went back and changed the file name. I then learned that this is a bad idea, because I changed the name of the folder in messed up the file path. This resulted in the data from the file connections I made t...

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...
