Lab 4: Pedestrian Networks @ University of Wisconsin Eau Claire

Image
Goal: The goal of this lab was to apply what we learned in the two network analysis workshops on ESRI's website.  A network data set was created to process and understand a real-world network problem that someone could potentially face.  The problem we worked on was the exploration of the Garfield Avenue construction project at the University of Wisconsin Eau Claire, which has been drastically affecting pedestrian traffic since the fall of 2017.  More specifically, two routes were tested in this lab:  the route pedestrians were forced to take in the fall of 2017 due to construction, and the new route that has been established currently in spring of 2018. Additionally, a question was answered upon completion of the entire network analysis. Question:  What is the difference between the two routes in terms of distance and time?  Were pedestrians losing time on their commute in the fall, and if so, how much time was lost? Methods: After completing the...

GIS 337 Lab 3 - Delineating Watersheds

Image
Goal and Background: The goal of this lab was to examine and learn how to delineate watersheds in order to understand the flow of the water, and in to further prevent pollution from entering the watershed.  By knowing the boundaries of a watershed, hydrologist professionals can understand how to protect and sustain the water quality in an area where water enters. Methods: Part 1: Data Processing To begin the lab, data about the Adirondack Park from upper New York State was unzipped as well as data from a hydrology shapefile from Cornell University.  In addition to that data, an digital elevation model (DEM North America) was used from ArcGIS online.  Using analysis tools, a 20 km buffer was created around the park boundary later so that the data would be presented more clearly.  The hydrology shapefile was projected to match the coordinate system of the park boundary layer, which happened to be North America NAD 1983 projection.  Raster clipping was then...

Lab 1

Image
Goal and Background: The goal of the first lab of GIS II is to review content and information from GIS I, such as symbology within cartographic design, understanding attribute tables, and normalizing data. Methods: This lab requries students to follow specific lab instructions and follow up by answering eight questions provided by the instructor that correspond to the lab exercise. Question 1  "What are the Geographic Coordinate System(GCS), Projected Coordinate System(PCS), and projection of the ‘street’ shapefile in the ‘Lab1Data’ folder?" To answer this, I opened the properties of the 'streets' shapefile and looked under the source tab to find all three answers. 2.  In your own words, describe what ArcCatalog is. What are the advantages of using ArcCatalog instead of Windows Explorer? To answer this, I looked up the details of Arc Catalog and its advantages using the ESRI website, and then put the answer into my own words.   3.  What is the...
