Module 3 - LiDAR: Visibility Analysis


Over the past week, I completed four Esri web courses that expanded my understanding of 3D GIS in ArcGIS Pro, focusing on visualization, analysis, and sharing tools. The course Introduction to 3D Visualization provided a solid foundation in navigating 3D scenes, converting 2D features using elevation surfaces, and using extrusion and real-world base heights to enhance spatial understanding. In Performing Line of Sight Analysis, I learned how to analyze visibility between observer and target points, which is useful for assessing obstructions in fields like urban planning or security. The Viewshed Analysis course introduced raster-based visibility modeling, showing how elevation and observer location affect what areas are visible on a map—a critical skill for tasks like emergency response planning or site selection. Finally, Sharing 3D Content Using Scene Layer Packages taught me how to package and publish 3D data for web use through Scene Layer Packages (SLPKs), streamlining collaboration by making 3D content accessible online. Together, these exercises provided valuable tools and techniques that I can now apply to build more dynamic, informative 3D maps and analyses.

Module 1- Overview of ArcGIS

This week was a good intro to the program and a good start to getting used to how the system works. It will just take more practice to get used to where things are and what they do.

Module 5: Data Points and Geocoding

  Manatee County Schools - Overview      Here is the Link to my map for this week.      The map this week is the locations of all the schools located in Manatee County, Florida. It contains information such as the coordinates, addresses, and names of the schools. Schools of all grade type are on the map. I.E elementary through college.         This weeks experience was different because we got to use Excel and partially collecting our own data from different sites. This week felt a little easier, because I have experience with Excel and I enjoy getting to use it for new things. It was nice having the labs feel a little shorter, but still learning just as much. It was easier to manage, and understand, without the potential to feel overwhelming, which I enjoyed. I didn't run into any issues in these labs, everything ran smooth.

Module 6: Georeferencing, Editing, & 3D.

Image
  This map is a georeference of three different raster images of the UWF Campus in Pensacola, Florida. The map also includes the location of a Bald Eagle nest that was found by the FWC, and the subsequent easement that was created around the nest to protect it from harm. This week's experience was pretty fun! I really enjoyed georeferencing. Matching the older pictures of the campus with the modern day map was a cool experience. Setting up control points on the map was pretty straight forward, and I felt pretty confident following the steps and indicators. I found editing the map features interesting because it was a way to add more information to show certain characteristics that need to be highlighted. Working on the 3D map was fun because it showed me a more realistic view of what the area actually looks like, which I enjoy more than the generalized maps that we have looked at previously. The following map is a georeferenced of the UWF Campus as well, on 3D scene:
