Abstract

Systems and methods present descriptions of conditions with respect to a surface by preparing and displaying a graphic presentation that includes a perspective view of the surface and at least one body apart from the surface. A graphic feature of the body is in accordance with a condition to be displayed. Applications include the display of lightning density over a surface of the earth.

Claims

1. A method performed by one or more processors, the method comprising preparing first data for a graphic presentation that portrays:

a surface having a region; and

a body separated from the surface, a projection of the body onto the surface defining the region, wherein a graphic feature of the body is in accordance with second data associated with the region.

2. The method of claim 1 wherein the graphic feature comprises a dimension of the body.

3. The method of claim 2 wherein the graphic feature comprises a color of the body.

4. The method of claim 1 wherein the graphic feature comprises a shape of the body.

5. The method of claim 1 wherein the graphic feature comprises a texture of the body.

6. The method of claim 1 wherein the graphic feature comprises a distance between the body and the surface.

7. The method of claim 1 wherein the region has a closed perimeter.

8. The method of claim 1 wherein the region is indicated by a color of the surface.

9. The method of claim 1 wherein the region is indicated by a texture of the surface.

10. The method of claim 1 wherein the surface includes relief in accordance with third numeric data associated with the region.

11. The method of claim 1 wherein the surface includes color in accordance with third numeric data associated with the region.

12. The method of claim 1 wherein:

the second data comprises a plurality of subsets each subset having a respective age;

the color of the region is in further accordance with a respective color of each subset and a respective transparency of the color of each subset; and

each respective transparency corresponds to the respective age.

13. The method of claim 1 wherein the surface comprises a map of physical features.

14. The method of claim 1 wherein the surface comprises a map of political features.

15. The method of claim 1 wherein:

the region comprises a first plurality of pixels, each pixel of the first plurality corresponding to a respective location of the region of a plurality of locations; and

the body comprises a second plurality of pixels, each pixel of the second plurality having a respective value in accordance with a portion of the second data associated with a respective location of the plurality of locations.

16. The method of claim 1 further comprising repeating preparing respective first data for a sequence of graphic presentations wherein each respective region of each presentation consists of locations at which a common condition exceeds a common threshold.

17. The method of claim 1 further comprising repeating preparing respective first data for a sequence of graphic presentations wherein for each difference of position of respective regions of sequential presentations there is a corresponding difference of position of respective bodies of the sequential presentations.

18. The method of claim 1 wherein the presentation further portrays an object between the surface and the body.

19. A method performed by one or more processors, the method comprising:

accessing first indicia of identification of a plurality of locations relative to a surface;

accessing a respective value in accordance with each location of the plurality of locations to provide a plurality of values; and

preparing data for use by a provided display process, the data describing a first graphic representation in accordance with at least a subset of the plurality of values, wherein the display process, in response to the data, displays the first graphic representation a distance from a provided representation of the surface, and distinguishes the subset as a projection of the first graphic representation onto the surface.

20. The method of claim 19 wherein:

the data further describes a second graphic representation in accordance with the respective locations that correspond to the subset of the plurality of values; and

the display process, in response to the second graphic representation, displays a portion of the provided representation of the surface in accordance with the second graphic representation.

21. The method of claim 20 wherein the data further describes the second graphic representation as a combination of colors rendered to a particular pixel of the second graphic representation, each color having a respective transparency.

22. A method performed by one or more processors, the method comprising:

accessing first data describing a region of a surface, the surface further comprising a second portion not within the region;

accessing second data describing a condition with respect to the region; and

preparing third data for use by a provided display process, the third data describing a first graphic representation in accordance with the first data and the second data, wherein the display process, in response to the third data, displays the surface in a perspective view, displays the region visually distinct from the second portion of the surface, and displays the first graphic representation in perspective view at a distance away from the surface.

23. A method performed by one or more processors, the method comprising:

accessing first data describing a first graphic representation in accordance with a condition with respect to a surface; and

combining the first data with second data describing the surface to provide third data, the third data for use by a provided display process, wherein the display process, in response to the third data, displays the surface in a perspective view, and displays the first graphic representation in perspective view at a distance away from the surface.

24. A method performed by one or more processors, the method comprising:

forming a graphic presentation that describes a plurality of lightning discharges above ground, the presentation including indicia of an in-cloud lightning discharge at an atmospheric location and including a ground surface onto which the location is projected;

wherein

the presentation is in accordance with a reference time;

each lightning discharge of the plurality has an age relative to the reference time; and

a color of a pixel of the graphic presentation is determined by combining overlapping lightning discharges of the plurality in further accordance with the respective ages of each overlapping lightning discharge to be combined.

25. A method comprising outputting a signal that comprises indicia of a presentation resulting from a provided performance of the method of claim 24.

26. The method of claim 25 wherein the signal is adapted for propagation via a digital link.

27. The method of claim 25 wherein the signal is adapted for television display.

28. A method performed by one or more processors, the method comprising forming a graphic presentation that describes a plurality of lightning discharges, the plurality comprising discharges above ground and discharges to ground, each discharge above ground having a respective location as projected onto the ground, each discharge to ground having a respective location at the ground, each discharge having a respective age, the presentation including a plurality of pixels, each pixel corresponding to a location, each pixel having a color in accordance with a total quantity of discharges of the plurality at the pixel location and having a transparency in accordance with the respective age of each discharge of the total quantity at the pixel location.

29. A method performed by one or more processors, the method comprising forming a graphic presentation that describes a plurality of lightning discharges, the plurality comprising discharges above ground and discharges to ground, each discharge above ground having a respective location as projected onto the ground, each discharge to ground having a respective location at the ground, each discharge having a respective age, the presentation including a plurality of pixels, each pixel corresponding to a location, each pixel having a color in accordance with a quantity of discharges to ground of the plurality at the pixel location and having a transparency in accordance with the respective age of each discharge of the total quantity at the pixel location.
