The goals for this lab were to analyze Microsoft Excel data, create data using Display XY, Points to Line Feature tools, explore the Marker Symbol Options, create a VB script for labeling, prepare data for processing in a geodatabase, perform a raster mosaic, use the flicker and swipe tool, prepare post-storm damage assessment data using attribute domains, locate and identify attributes and generate a report for a study area. The bulk of my time spent on this lab was comparing the pre and post storm data, which was created with mosaic datasets, adding domains and creating a feature class to digitize storm damage to parcels. The final outcome of the project is numerical data representing the levels of damage to parcels within 100 meters, 200 meters and 300 meters of the coastline. The final results were that most of the significant damage (ie: building destroyed) occurred within 100 meters of the coastline. However, interestingly enough all parcels within  300 meters of the coastlin...

The objectives of this lab were to become familiar with procedures for coastal flooding assessment, understand different elevation models, perform overlay analysis to examine differences in DEMs, and determine errors using different DEMs. I enjoyed this lab partially because I am most interested in coastal erosion due to storms and climate change. Additionally, part of the lab was done in Collier County, which is immediately south of my county. Overall, I am satisfied with how my maps turned out, and happy learning new skills with  creating masks and complex attribute queries.

 The objectives for this lab assignment were outlined with the help of Esri's learning plan on Get Started with Visibility Analysis.  The completed courses in the plan were Introduction to 3D Visualization, Performing Line of Sight Analysis, Performing Viewshed Analysis and Sharing 3D Content Using Scene Layer Packages. In the first course, Introduction to 3D Visualization, I learned the basics of 3D visualization and the range of applications and the techniques by analyzing aspects of a 2D and 3D creation of Crater Lake in Oregon. The second and third course, Performing a Line of Sight Analysis and Viewshed Analysis, focused on how to identify obstructions between observed and target points, which has a real world application of establishing security parameters to ensure there are obstructions in the viewpoints. The final course, Sharing 3D Content, shared tools on how to export 3D scene layers to ArcGIS Online.

  The objectives for this lab were focused on creating Digital Elevation Models, Digital Surface Models, calculating forest height and biomass from LIDAR data. I believe I achieved all these objectives, the only issues I ran into were the amount of time it took to run each geoprocessing tool. I was able to familiarize myself with geoprocessing tools such as LAS to MultiPoint, IS NULL, Float, Plus and Con. All in all, this lab went well and I'm happy with how my maps turned out.

  The objectives for this week's lab included learning crime analysis techniques, determining crime rates, examining spatial patterns in crime rates and socioeconomic characteristics, practicing spatial cluster and comparing reliability of crime hotspot mapping. I became familiar with some geoprocessing tools like creating a mask by setting environmental parameters, creating kernel density maps and also using the intersect tool to distinguish patterns between layers. Ultimately, I learned a lot in this lab, but struggled with time and was unable to complete portions.
