Abstract
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.
