Patent ID: 8270769

Claim:
A method of tracking assets within a structure using a digital viewer in which the digital viewer includes a two dimensional display means displaying a two dimensional digital image of a scanned paper document of a structure, scale information of the paper document being embedded in a header of the two dimensional digital image, wherein the improvement comprises: displaying a three dimensional rendering of said two dimensional digital image in a three dimensional display means, said three dimensional rendering having a three dimensional coordinate system, said three dimensional coordinate system being a non-rendered grid disposed on said three dimensional rendering, said two dimensional digital image having a two dimensional coordinate system, said two dimensional coordinate system being a non-rendered grid disposed on said two dimensional digital image; providing a common coordinate system, wherein said common coordinate system is formed by matching said non-rendered grid of said two dimensional digital image to said non-rendered grid of said three dimensional rendering; providing a receiver location about the structure; and providing an asset with a receiving/transmitting device; wherein location of said asset within said structure can be detected on said common coordinate system, and wherein said two dimensional digital image is linked in real-time and coordinate matched with said three dimensional rendering.
