On Monday students in Field Instruction had a lesson in using GPS units to find locations based on latitude and longitude as well as on one method of creating a topographical maps. After a short lesson students were divided into groups of three and they headed out to towards the Conserve School sledding hill area. This area was selected because the altitude varies signficantly over short distances and the lack of trees improves the accuracy of the GPS readings.
Each group was given a GPS unit which measures location and altitude as well as 33 locations to make altitude measurements. Every class all of the measurements were combined to make a map of the area. It was a great way to learn about the GPS units and the students enjoyed the unusually warm spring weather. Unfortunately the map wasn’t as accurate as it might have been because the air pressure which the GPS units use to measure altitude was being heavily influenced by a weather front that was moving through.
Enjoy the pictures!
