Data Points in a Geodatabase

Stations (site specific data)
	[kind] O = generic observation
	[kind] A = age
	[kind] G = graphic data
	[kind] R = sample sites
	[kind] Y = analytical
Age categories (prefix 1)
	a = Argon-Argon
	r = radiocarbon
	t = tephrochronologic
	c = cosmogenic
Graphic data categories
	p = photograph
	s = sketch
Sample site categories
	r = rock
	s = sediment
	t = tephra
Analytical categories
	f = fluvial transport direction
	g = fluvial gravel lag

This is the structure of point data that we have built into the geodatabase for the Owyhee River mapping project. It covers all of the ground that is presently relevant to that project, but would need to be modified for a bedrock / structural map, for example.
