MULTIPLE RESOLUTION NON-LINEAR TERRAIN MAPPING SYSTEM

摘要

A method and apparatus for creating non-linear maps that simultaneously displays multiple “defined areas of interest” on a map at different resolutions than the resolution of an underlying map is disclosed. A standard map, along with map layers containing the locations and data for domain-specific “areas of interest” are inputted. A Map Truth Table creates the key map coordinates that define the map areas that will be viewed in a higher resolution than the underlying map. This information is further processed to produce the final non-linear map output. Such a map could show, for example, local street-level details of areas with severe earthquake damage on a map covering 250,000 acres.

主权项

1. A system for generating map views, comprising:
an import interface that receives a map area from a device; an interest module that defines an interest metric that varies as a function of a location in the map area; an AOI module that defines a first area to expand and a second area to expand in the map area as a function of the interest metric; an expanded view module that defines a first set of dimensions of a first zoomed-in view of the first area to expand and a second set of dimensions of a second zoomed-in view of the second area to expand; a map generator that generates an overall view of the map area and overlays the first zoomed-in view having the first set of dimensions and the second zoomed-in view having the second set of dimensions over the overall view on a display.
