Poles of Inaccessibility in the San Gabriel Mountains
A developer computes the Pole of Inaccessibility for the San Gabriel Mountains — the point furthest from any road or trail — using OpenStreetMap data and Voronoi diagrams. The approach projects geographic coordinates onto a local tangent plane, samples roads at 100m intervals, builds a Voronoi diagram using boost::polygon, and finds the vertex with the greatest distance to its nearest input point. Three variants are computed: avoiding all roads and trails (4.3 km), roads only (5.7 km), and paved roads only (8.2 km). All three poles cluster above the East Fork of the San Gabriel River near Ross Mountain and Iron Mountain.
