Summary

A visual depiction of how using a sight line along a building face can help to reduce the position ambiguity of a GPS unit. Standing close to a building blocks the GPS signal reception, degrading position accuracy even more than normal. Moving out away from the building gets a clear sky view, and that combined with the extended length of the wall can be used to reduce the error of the actual measured item. Draw lines between the extended points, and use them as guides to draw the actual building outline.
