Indoor navigational route enhancements using contextual data implied by map colors

[0012]In architecture and building engineering, a floor plan is a drawing to scale, showing a view from above, of the relationships between rooms, spaces, traffic patterns, and other physical features (e.g., structural interiors, interior walls, hallways, windows, doors, etc.) at a level of a structure which may or may not include an outdoor space. Indoor and outdoor navigable routes for a floor plan may frequently change as civic planning progresses or as buildings are remodeled to meet the changing needs of an organization. While there are several commercial systems on the market for indoor navigation, there are no standards for an IPS system. Traditionally, the navigational mapping of such routes is achieved using graphs of nodes and vertices which are generated, overlain, and mapped to paths or areas on a digital map representation of an indoor layout (e.g., a floor plan) of a structure which may or may not include an outdoor space. This process of indoor navigational mapping ma...
