Here's the GPS Surveying Protocol. Post some comments with thoughts, ideas, and changes.
2010 Stipa Draft Protocol.pdf. The Google Docs wasn't really working out... Comment with your thoughts and changes.
Today we will start measuring Echinacea in the Common Garden. Here is the link to the protocol: CGmeasureprotocol2010.htm
So these are the Stipa that have been collected so far. I've labeled a couple of the places on the map.
I was having trouble projecting the data exported from GPS Pathfinder Office (trimble) and noticed that no coordinate system was defined (same issue with the DOQ maps Stuart gave me; the GeoTIFFs didn't have a spatial definition). The GPS data should be North American 1983 in the Geographic Coordinate System folder (right click on the data in ArcCatalog, hit the XY Coordinate System tab and hit the Select button). The DOQ maps ought to be using the NAD_1983_UTM_Zone_15N from the Projected Coordinate System folder. Dumping all of these files into ArcMap (and a little fiddling) gave me this nice map.
Next plan of attack is to make it work in GPS Pathfinder Office, as it's much less complicated than ArcGIS.
Josh, Gretel, Hillary, and Ian are also trained on the TopScan to collect the GPS data. The ideal is that the radio signal is at 100% and the designation of the location is described as Fixed - (Float will do and Auto works if you are unable to connect to a radio signal)
Josh and I plan to collect from Hegg Lake and the road adjacent on Monday. In the quest to collect from 300 parent plants, we are likely onto roadsides - where we are trying to stay at least a meter off the road and using plants about 5m apart from each other. Generally, as the black color appears and as the capsule opens around the pointy head, the seeds are ripe and will pop off as you gently pull up the stem containing the seeds.
I plan to be around Sun afternoon and Mon. to finish the collection before starting to cross some plants.
