Dynamically updating map projections

摘要

Embodiments of the invention may provide the ability to dynamically create and update map projections to reduce the spatial distortion in a desirable way for a specific map view. For example, as a map view is changed, a new central meridian may be selected and a new map projection may be created based on the selected central meridian. Dynamically updating map projections so that all map layers are correctly representing the most important spatial attributes for the given situation may enable a map analyst to correctly interpret the maps being viewed.

主权项

1. A system for displaying map projections comprising:
a processor configured for, in response to one or more desired changes to one or more aspects of a map view, selecting a central meridian for the desired changed map view, and configured for creating a new map projection based on the selected central meridian; and a display for displaying the new map projection, wherein the new map projection has one or more differences in distortion from a prior map projection based on a prior central meridian.
