Last week I had the opportunity to help a fellow consultant with his sampling in the "real" southern Illinois. He emailed me a shapefile of the fields he wanted sampled several days before. I converted it to a Google Earth format and zoomed in as close as possible. It was close enough to see towns and have a relative idea where things were.
I left home very early in the morning. My friend led me close to the first field I needed to work on and I used GPS to make sure I was there. I continued to sample, stopping a total of 7 times. The whole time, I used the GPS and the Google Earth map to navigate. It was amazing that I was able to find and sample all the fields. Without GPS, we might have spent hours just on directions.
