Please use these notes in any way allowable by the w:GNU FDL. However, you might want to drop me a line in my talk page after you make a wikipedia article from this information, so that I don't make a similar article from the same data. I also plan on somehow marking the text in this file that has already been incorporated into wikipedia.

=== Research method ===
1) Observational Study (uses w:scientific method)
- w:Observation -> w:Hypothesis -> w:Experiment -> w:Theory
Often, experiment leads back to another or modified hypothesis 2) Controlled Experience 3) Controlled Experiment
== GiS Essentials == (questions it answers answers)
1) Unique IDs (who? what?)
2) w:Coordinates (where? when?)
3) w:Metadata (why? how?)
