Abstract

GeoDesigning in the Cloud: Online design of Low Distortion Projections
Track: Surveying
Authors: Michael Dennis

Map projections are distorted (a Fact of Life). Linear distortion is difference in distance between projected coordinates and true ground distance. Low Distortion Projections (LDPs) minimize distortion by covering the largest area with the least distortion possible. But these goals are mutually exclusive, so it is an optimization problem. We show how it can be solved using LDP Design, an online application with an intuitive map-centric interface for interactively designing LDPs in the Cloud.
