Map layersProjection diagnostics

Tissot's indicatrices

Equal-sized circles on the globe. Their distortion on the map instantly reveals how the projection alters area and shape.

Arrows show where geographic north lies on the screen. Their rotation reveals how a projection alters directions.

Geographic context

Equator, tropics & polar circles

Five major parallels anchor Earth's zones and reveal how the projection stretches high latitudes.

Ocean currents

An animated, simplified view of major surface currents — especially revealing on ocean-centred projections.

Day & night
