So, once upon a time, a naive undergraduate from the University of Texas applied for graduate school in archaeology. She sent out a statement of purpose that boiled down to: “I want to be able to embed archaeological information in the landscape, and I want other people to be able to add to that information…on my cellphone.”
Three years later, that’s what I did. There’s several ways to do this, and this is obviously a kludge, but it’s a start. I’ll probably load the full documentation up to the Presidio field blog later tonight.
