Before we started the tree study today, we learned that there are different ways to record latitude and longitude. We changed the settings on our GPS to be in decimal format, in order to easily upload the data to GIS. We learned that South and West are recorded as negative values in GIS. Once we were finished, we created an excel spreadsheet (.csv file) and uploaded the table to arcgis as a layer to the map. Here we could change the icons to better represent the data.
We had a really neat presentation on water glyphs by Cody Spendlove. It was totally fascinating. There is a website here. There are these circle symbols located all throughout the united states that have a line through them and dot somewhere near. Through their research they were able to find that, in most cases, it points to a water source or some other significant place (wild cat cave). They also showed us this cool map.

He also talked about three rules:
1. Just because you found it, doesn't mean it was lost
2. Just because you don't know what it does, doesn't mean it doesn't have a purpose
3. Just because you know something, doesn't mean you have the right to share it.
