Forestry LiDAR Mod02

The forestry LiDAR lab focused on creating DEM & DSM, calculating forest height, and calculating forest biomass from LiDAR data. A laz file from Virginia LiDAR application was used and converted to a las dataset. From this the point file information and LAS Dataset to Raster tool were used and a DEM and DSM layer were created. (Figure 1) The DEM and DSM were used in the minus tool to create a height raster layer. A histogram chart was also created to complement the height map to show the distribution of the values. (Figure 2) The LAS to MultiPoint and Point to Raster tool were used to help calculate the biomass density. The is null, con, plus, float, and divide tool were then used to calculate the density. In the divide tool the vegetation count result and the float result were used. (Figure 3)

Intro to GIS - Lab1 Overview of ArcGIS

Image
  First week of learning GIS! During this week's introductory lab, I began building the groundwork for mastering the software. The lab focused on the basics of ArcGIS and how to navigate the software. While the program initially seemed straightforward to navigate, the overview lesson went into greater detail on various features within the software. Upon completing the first lesson, I feel more comfortable in navigating the software and how it can be used to better understand data. I am happy with how my first map turned out, mapping different major cities across the globe. I eagerly anticipate upcoming lessons to further my knowledge and understanding using ArcGIS.

About me

Hello! My name is Addison and I am originally from Pensacola. I graduated from the University of West Florida in 2022 with a bachelors in marine biology. I am currently working full time for the Florida Department of Environmental Protection. I joined the program because I had been interested in GIS and wanted to gain knowledge and skills in the GIS world. I hope to use what I learn from these courses to further my career.

Final - Bobwhite-Manatee Transmission Line

In this final lab we used multiple skills learned throughout the course to analyze the proposed route for a transmission line from Manatee County to Sarasota County. The four main criteria that needed to be analyzed were environmentally sensitive lands, homes, schools, and the length of the transmission line. Although learning the technical aspects of ArcGIS was challenging for me, but I enjoyed the challenge and see everything come together in a final product.  Bobwhite Manatee Transmission Line Transcript
