Datum conversion factor
WebTransformations between old datums (NAD27, Old Hawaiian, Puerto Rico, etc.) and HARN could combine uncertainties (that is, NAD27 to HARN equals 0.15 m + 0.05 m = 0.20 m). In near offshore regions, results will be less accurate but seldom in excess of 5.0 m. Farther offshore, NAD27 was undefined. Webtransformation is a set of math formulas that converts point coordinates from one datum to another. Datum transformations take place in three-dimensional space, but you can get a sense of how they work from a two-dimensional example. Suppose you have two different maps of the same set of points. The differences between them can be expressed
