- Distortion class
- Equal-area
- Graticule type
- Pseudoconic
- Creator
- Johannes Werner (based on Johannes Stabius' design)
- Year
- 1514
- Area
- Preserved (equal-area projection)
- Shape
- Distorted: only the central meridian is free of distortion, and deformation grows with distance from it (strongest at the edges of the heart)
- Distances
- Partially preserved: true along every parallel and the central meridian, and from the North Pole to every point
- Angles and directions
- Distorted, especially near the outer margins
Add countries from the tools panel and drag them to other latitudes. The outline keeps its true shape and area on the globe, so any change in its size on the map shows this projection's distortion. Tissot's indicatrices and the area distortion map show the same effect across the whole world.
