After today, we covered everything for Buffer Projects except for GAT

First, we will take a look at the Buffer Project structure

New Data Sources:

  1. National Atlas
    1. No WinZip, WinRar, or equivalent on your computer to open the .TAR files from National Atlas? Download Peazip. Is free, safe, and can even be run as a portable app from a USB drive.
  2. Texas Park and Wildlife Division
Proximity Calculations:
  1. Near (ArcToolbox/Analysis Tools/Proximity/Near)
  2. Point Distance (ArcToolbox/Analysis Tools/Proximity/Point Distance)
Proximity Exercise:
  • Take this table (download table) and calculate the straight-line distance from each location to UT Arlington Library.
    • To create the UT Arlington Library point, first ensure you have the Bing aerials viewed. (File/ArcGIS Online, search for Bing). Second, geocode as we normally do to the University address and then move the point to the Library. Third, convert the graphic to a feature class.
    • We can use either the Near or the Point Distance tool for this exercise.
Calculate Slope:
  • We will use the Spatial Analyst Extension. The extension needs to be enabled before we can use it.
    • Customize/Extensions and check Spatial Analyst
  • ArcToolbox/Spatial Analyst Tools/Surface/Slope
