Equal Area Projection
Projection which preserves the area of the area of interest shown but does not preserve the real-world distance or shape.

Fuzzy Boundary
A boundary that is treated as band of uncertainty.
Equal area projections preserve the property of area. On an equivalent projection all parts of the earth's surface are shown with the correct area. However, latitudinal distances are never accurate.
equal area projections preserve the area of features by assigning them an area on the map which is proportional to their area on the earth - these are useful for applications which require measuring area, and are popular in GIS ...
Project DEM to an equal area projection (Lambert Azimuthal Equal Area was used for North America).
Use standard filling functions to fill the entire DEM without consideration of maintaining any sinks.
Nor was the concept that an equal area projection was preferable to the Mercator projection at all new to USA school textbooks.
Equal area projections are useful when looking at small features; on a map created with this projection each unit of area (a square meter or a square kilometer) at one location of covers a square meter or a square kilometer on every other map ...
The Bonne projection is a pseudo-conic equal area projection once widely used in atlases. It has since been replaced by the use of Lambert's azimuthal equal-area projection.

Both are pseudoconic, equal area projections. Click on the maps for full sized versions. I liked the Laskowski Minimum Error projection display by Paul B. Anderson so much that I decided to impose on him for this pair! ...

which are not based on the cylinder, including conical projections (based on the model of a cone, placed with its vertex immediately above one of the poles) and entirely separate families of projections such as two-world equal area projections and ...
