Abstract

The system includes a method of mapping a building indoor floor plan onto a physical map projection and provides a visual depiction thereof. The system and method is implemented in a computer system wherein each floor of a building is visually mapped from its relative (x, y) position into its real world (x, y) position.

Claims

1. A method for utilizing a processor, a display and a non-transitory computer storage media, the method to create an indoor floor map of a building comprising the step of:

generating a real-world objects database stored within the non-transitory computer storage media containing a plurality of longitude and latitude positions for real world elements in a locality where the building is located, wherein a satellite is utilized to survey a plurality of real world objects of the earth surface;

the processor creating a relative x and a relative y position for the building having a plurality of visual elements, selecting a subset of visual elements from the plurality of visual elements for a desired floor in the building and implementing a mapping system which interfaces with the satellite to receive a plurality of longitude and latitude information through a GPS satellite receiver that is imported into the real-world objects database;

for each desired floor in the building generating a three-dimensional top plan view on the display showing the subset of visual elements, the satellite generates a satellite photograph of the building location;

for each element within the subset of visual elements generating a correlate x position and a correlate y position based upon the relative x position and the relative y position of the building, the satellite captures, collects and stores the earth surface information and transmits that information to be stored as a plurality of digital data objects in the database;

for each element within the subset of visual elements generating a name tag which represents the correlate x position and the correlate y position of the building;

generating a correlating database structure containing a record which represent each element within the subset comprising the name tag and the correlate x position and the correlate y position;

based upon the relative x and relative y position for the building, generating a real world longitude and latitude position for the building in that locality;

based upon the real-world longitude and latitude position of the building determine an adjusting scale;

adjusting the record containing the relative x and relative y position in the correlating database to a real-world longitude and latitude position for the building using the adjusting scale; and

generating upon the display a visual representation of the desired floor of the building using the real-world longitude and latitude position.

2. The method of claim 1, further comprising generating a three-dimensional top plan view of the desired floor showing the subset of the visual elements based upon the name tag and the relative x and y position.

3. The method of claim 2, further comprising generating the three-dimensional top plan view of the desired floor showing the real-world longitude and latitude position.

4. The method of claim 3, further comprising generating the three-dimensional top plan view of the desired floor showing the subset of the visual elements based upon the name tag and the real-world longitude and latitude position.

5. The method of claim 1, wherein the subset of visual elements is selected from the group consisting of a door, a wall, an elevator, a camera, and an exit door.

6. The method of claim 1, wherein the subset of visual elements is selected from the group consisting of a point, a curve, and a line.

7. A non-transitory computer storage media, having instructions stored thereon which, when executed, execute a method comprising the steps of:

generating a real-world objects database stored within the non-transitory computer storage media containing a plurality of longitude and latitude positions for real world elements in a locality where the building is located, wherein a satellite is utilized to survey a plurality of real world objects of the earth surface;

the processor creating a relative x and a relative y position for the building having a plurality of visual elements, selecting a subset of visual elements from the plurality of visual elements for a desired floor in the building and implementing a mapping system which interfaces with the satellite to receive a plurality of longitude and latitude information through a GPS satellite receiver that is imported into the real-world objects database;

for each desired floor in the building generating a three-dimensional top plan view on the display showing the subset of visual elements, the satellite generates a satellite photograph of the building location;

for each element within the subset of visual elements generating a correlate x position and a correlate y position based upon the relative x position and the relative y position of the building, the satellite captures, collects and stores the earth surface information and transmits that information to be stored as a plurality of digital data objects in the database;

for each element within the subset of visual elements generating a name tag which represents the correlate x position and the correlate y position of the building;

generating a correlating database structure containing a record which represent each element within the subset comprising the name tag and the correlate x position and the correlate y position;

based upon the relative x and relative y position for the building, generating a real world longitude and latitude position for the building in that locality;

based upon the real-world longitude and latitude position of the building determine an adjusting scale;

adjusting the record containing the relative x and relative y position in the correlating database to a real-world longitude and latitude position for the building the adjusting scale; and

generating upon the display a visual representation of the desired floor of the building using the real-world longitude and latitude position.

8. The non-transitory computer storage media of claim 7, further comprising generating a three-dimensional top plan view of the desired floor showing the subset of the visual elements based upon the name tag and the relative x and y position.

9. The non-transitory computer storage media of claim 7, further comprising generating a three-dimensional top plan view of the desired floor showing the real-world longitude and latitude position.

10. The non-transitory computer storage media of claim 7, further comprising generating the three-dimensional top plan view of the desired floor showing the subset of the visual elements based upon the name tag and the real-world longitude and latitude position.

11. The non-transitory computer storage media of claim 7, wherein the subset of visual elements is selected from the group consisting of a door, a wall, an elevator, a camera, and an exit door.

12. The non-transitory computer storage media of claim 7, wherein the subset of visual elements is selected from the group consisting of a point, a curve, and a line.
