Analista GIS: Geodesia y Cartografía Precisa

Distances and bearings from the center are accurateDistortion increases rapidly away from the centerDistances and directions between non-central locations are wrongSo while the map can function as a practical educational or navigational tool from the pole, it fails for comparing distances or routes elsewhere — exactly what geodetic theory predicts.The modern interactive version by Khaled Mimoune, including adjustable daylight overlays, further illustrates how cartographic projections can visualize real-world phenomena (like illumination and seasons) on a flat surface. From a surveying perspective, this reinforces the distinction between:The Earth (a globe)A map (a mathematical projection of that globe)In short, Gleason’s map doesn’t demonstrate a flat Earth. It demonstrates that projecting a curved surface onto a plane requires distortion, a foundational principle in surveying, geodesy, and every State Plane Coordinate System used in professional practice today.Flat Earth does not surv...
