Observe data collection at the moment of measurement See, observe, learn how data are collected at moment and place of measurement. "You never learn more about a process than when you directly observe how data are actually measured," said Cuthbert Daniel, a superb applied statistician. See with fresh eyes. Walk around what you want to learn about. Talk to those who do measurements. See how numbers came to be. Do those measuring know the desired answer? Are those measuring skilled, alert, honest, biased, incompetent, sloppy, tired and emotional?...Artifacts and errors in measurements measured? How are outliers adjudicated?

Maps and observation Maps are useful only when they are used in combination with observation. Never try to design a site by just looking at a map, even if it is thoroughly detailed with contour lines, vegetation, erosion gullies, and so on marked in. Maps are never representative of the complex reality of nature. Remember, "The map is not the territory." Bill Mollison, Introduction to Permaculture BlueprintsGuided by image mapsrealityarchitecture
