Post 3: Data Gathering

The last part of our lab five was to look at the data we gathered.  Below us however is a map of Trempaleau County and its location within Wisconsin and the three rasters that we downloaded and put through the script. These datasets will become essential for us throughout the rest of the semester as we continue our analysis of Sand Mining in Western Wisconsin. I also included a table showing the differences in quality of the data that we gathered for this lab.

Post 2: Python Script

Lab 5 Script

In part two of Lab 5 we were tasked to write our first Python Script. Python is a coding software that helps us do jobs within arc that may be difficult to do manually. Although Python is hard to learn, once you gain these skills it will help you tremendously in the future and make your GIS life alot easier. For this script we took some of the rasters we downloaded, clipped them, and downloaded them into our new geodatabase for Trempaleau County.

Lab 7 Script

For part one of Lab 7 we were tasked to write out second Python Script. The reason being is so that we could select all the mines that we want to use for our final network analysis. To keep the script clean we made several variables. This script also contains three different SQL statements and two Select by Location queries. My script gave me a total of 41 mines. I have looked through the data and this number seems about right as far as how many mines are active and are 1.5 km away from a rail terminal.
