Map Evidence Lab

Maps

Historical maps, projections, geographic evidence, scriptural cosmology, and institutional symbolism — with sources, uncertainty, and clear separation between artifact facts and interpretation.

Compare continents

One dataset. Two projections. Three valid views.

The continent outlines never change — the projection math does. No image is manually stretched. Overlays are meaningful only when both layers share the same projection; otherwise you're comparing framing, not shape.

View
A · Equal EarthShape, especially near the edges.
B · MercatorArea, strongly toward the poles.

Discipline

  • Both layers come from one dataset: Natural Earth 1:110m coastline / countries (via world-atlas TopoJSON). Any shape difference is projection math, not different geography.
  • Nothing is scaled by eye. Each SVG is drawn from lat/lon coordinates by d3-geo.
  • A flat map is never faded over the spherical globe. The Globe tab renders the sphere as its own view.
  • Overlay is disabled when projections differ, because it would misrepresent the mathematics.
