First Claim
1. An improved method for providing information of a digital raster image of the type whereindigitizing a paper document to create a digital raster image,recording scale information associated with the paper document and a digitizing device,embedding the scale information in a header of the digital raster image,storing the digital raster image as a first file, wherein said embedded scale information is embedded in said header of said first file,rendering the digital raster image in a digital image viewer wherein the improvement comprises:
- creating a three dimensional rendering of said digital raster image, wherein said three dimensional rendering has a three dimensional coordinate system;
storing the three dimensional rendering as a second file;
wherein said digital raster image has a two dimensional coordinate system,wherein said three dimensional coordinate system and said two dimensional coordinate system are matched and linked in real-time,wherein said digital raster image of the paper document and the three dimensional rendering of said digital raster image are capable of being viewed simultaneously.

Abstract
The present invention provides a true-scale, coordinate-matched, linked in real-time, dual three-dimensional/two-dimensional visual display/viewer. The display simultaneously shows a 3D digital image and an associated 2D digital image of a selected drawing. The display of the present invention allows a user to visualize an asset'"'"'s location, surrounding environment and hazards and true scale structural details for interior or external structural scenes. Using the display and associated tools, the user can obtain real-time information of an environment, true-scale measurement, plan ingress/egress paths, shortest paths between points and the number of doorways in a structure and track objects within the displayed environment. The intelligence gained using the tools and 3D/2D display may be used and further manipulated by a single user or may be distributed to other users.
