Week 14 Field Outing

 Introduction

Week 14 was the final week that AT319 students performed data collection missions at PWA for the semester. Once again, Aeropoint GCPs and ArcCollector were used to collect GCP data. Maps for the Aeropoint GCPs and ArcCollector GCPs are provided below with the other maps and insets. One student also used ArcCollector to record a walking path of the GCP placement. Five GCPs were used for this outing.

The weather was not ideal heading into the week 14 lab. While driving to PWA, many students reported a heavy rain shower. At the start of the lab, there were some snow flurries as well as graupel. This was the last snowfall of spring in Indiana. The weather cleared up within 20 minutes of the lab start and flights were completed.

Flight crews only flew one flight each in week 14. Due to the weather, the class had to operate within a short amount of time. Because of this, students had to communicate with each other and fly missions at the same time, much the same as in week 13. People working with the salamander tanks had concerns about the GCP placement and flight area that we chose in week 12. To account for this, the flight area was narrowed down to a strip that included the field plots.

Study Area

The field plots that were burned in week 13 looked the same in the week 14 data. Most of the PWA study area did not change between week 13 and week 14. The biggest difference in this dataset was the construction area. There was no construction in the first two datasets, only excavation. In week 14, construction started and a building foundation frame can be seen in one of the insets provided below.
