essentual questions in selecting map projections
Definition

1. Are the properties of a particular projection suited to the design problem at hand? Projection Properties

2. Are deformational aspects of the projection acceptable for the mapped area? Deformational Patterns

3. Can the projection be centered easily for the design problem? Projection Center

4. Will the projection and the appearance of its meridians and parallels be familiar to most readers? Familiarity

5. Is the particular projection supported in your software? Software Support

6. Does the map belong to a series that already has a projetion? Part of an existing map series or online digital map collection
