FIRST, DO NO HARM: ELIMINATING SYSTEMATIC ERROR IN ANALYTICAL RESULTS OF GIS APPLICATIONS

N. Chrisman and J.-F. Girres

Keywords: Systematic error, map projections, scale error, area, perimeter, correction of error

Abstract. GIS applications compute analytical results comprised of geometric measures such as perimeter, distance between objects, and area. Usual practice operates in Cartesian coordinates on map projections, inducing a systematic variation due to scale error. The magnitude of these errors is easy to foresee, though rarely corrected in analytical reports. Solutions to this error can be implemented though a number of alternative procedures.
