A system and method for displaying a chart or map such that the area in close
proximity
to an area of interest is in greater scale than an area that is distant and creating
the image dynamically. The method includes a projection function capable of creating
or reading reduced scale cache images and displaying those images concurrently
with full detail source chart images. The system includes hardware such as a processor,
a memory storage device, a drive, a input device among others, and software such
as a navigational software program, cache images, and a projection function among
other things to produce a spherical view of a displayed electronic chart
