Summary and Guide to Projections

Cartographers often choose map projections by determining the types of distortion they want to minimize or eliminate. They can also determine which of the three projection types (cylindrical, conic, or azimuthal) best suits their purpose and region of interest. They can attach special importance to certain projection properties such as equal areas, straight rhumb lines or great circles, true direction, conformality, etc., further constricting the choice of a projection.

The toolbox has about 60 different built-in map projections. To list them all, type maps. The following table also summarizes them and identifies their properties. Notes for Special Features are located at the end of the table. Information on Mapping Toolbox™ map projections can be found in Projections and Parameters.

  1. Straight rhumb lines.

  2. Rhumb lines from central point are straight, true to scale, and correct in azimuth.

  3. Correct total area.

  4. Straight line great circles.

  5. Great and small circles appear as circles or lines.

  6. Three-dimensional display (not a map projection).
