Abstract

Embodiments provide systems and methods for identifying one or more locations in a selected geographic region of interest. In certain cases a processor-executed method for generating location identification codes is provided. The method includes receiving information about a selected geographic region, a standard areal unit, and a predetermined set of characters, and then generating one or more location identification codes after determining the total number of areal units in the region and the number of character positions in the code. An interactive mapping system includes inputs/outputs, memory, and a processor programmed to receive a location identification code, retrieve and display a location description for verification, and retrieve and display map data corresponding to the location identification code.

Claims

1. A computer-readable storage medium comprising executable instructions for causing a programmable processor to execute a method for generating location identification codes for referencing locations within a geographic region, the method comprising:

receiving a geographic region selection;

receiving a definition of a standard areal unit representing a smallest identifiable subset of the geographic region to be identified by a location identification code;

determining a total number of the standard areal units in the geographic region;

determining a number of character positions in the location identification code based on the total number of the standard areal units in the geographic region and a predetermined set of characters; and

generating the location identification code for at least one standard areal unit in the geographic region, the location identification code comprising a character from the predetermined set of characters in one or more of the number of character positions.

2. The medium of claim 1, wherein the method further comprises receiving a definition of the predetermined set of characters.

3. The medium of claim 1, wherein the location identification code is a positional numeral having a base and wherein a total number of characters in the predetermined set of characters is the base.

4. The medium of claim 1, wherein the predetermined set of characters consists of consonants and numbers.

5. The medium of claim 4, wherein the predetermined set of characters consists of {B G H J L M N P R T V W X Y Z 4 6 7 8}.

6. The medium of claim 1, wherein the method further comprises assigning each of the standard areal units an index.

7. The medium of claim 6, wherein the method further comprises determining the index of the at least one standard areal unit and generating the location identification code based on the index.

8. The medium of claim 7, wherein the index has a first base, the location identification code has a second base and generating the location identification code comprises converting between the first base and the second base.

9. The medium of claim 1, wherein determining the number of character positions is further based on a number of altitudes for the standard areal units and wherein the method further comprises generating multiple location identification codes for the at least one standard areal unit, each of the multiple location identification codes corresponding to a separate altitude for the at least one standard areal unit.

10. An interactive mapping system, comprising:

an input device;

an output device;

one or more computer-readable storage mediums comprising executable instructions; and

one or more programmable processors programmed with the executable instructions to

receive a location identification code from the input device,

retrieve a location description using the location identification code,

display the location description using the output device, and

retrieve and display map data corresponding to the location identification code on the output device,

wherein the location identification code identifies one of a plurality of standard areal units within a geographic region of interest and

wherein the location identification code has a number of character positions based on a total number of the plurality of standard areal units within the geographic region of interest and based on a predetermined set of characters for generating the location identification code.

11. The interactive mapping system of claim 10, wherein the one or more programmable processors are further programmed to determine reference coordinates based on the location identification code.

12. The interactive mapping system of claim 11, wherein the reference coordinates for the location identification code correspond to a representative geographical point within the standard areal unit corresponding to the location identification code.

13. The interactive mapping system of claim 10, wherein the location identification code is a positional numeral having a base and wherein a total number of characters in the predetermined set of characters is the base.

14. The interactive mapping system of claim 10, wherein the one or more programmable processors are further programmed to convert the location identification code to an index and use the index to retrieve the location description.

15. The interactive mapping system of claim 14, wherein the index has a first base, the location identification code has a second base and converting the location identification code to the index comprises converting between the second base and the first base.

16. The interactive mapping system of claim 10, wherein the predetermined set of characters for generating the location identification code consists of consonants and numbers.

17. The interactive mapping system of claim 16, wherein the predetermined set of characters consists of {B G H J L M N P R T V W X Y Z 4 6 7 8}.

18. The interactive mapping system of claim 10, wherein the location identification code corresponds to one of a plurality of altitudes for the one of the plurality of standard areal units.

19. A method for providing map data, comprising:

entering a location identification code into a computer processor based interactive mapping system comprising

at least one programmable processor,

one or more computer-readable storage mediums programmed with computer-executable instructions, and

an electronic display,

the location identification code identifying one of a plurality of standard areal units within a geographic region of interest and comprising a positional numeral having a first base and a number of character positions determined according to

1) a total number of the plurality of standard areal units within the geographic region of interest and

2) a predetermined set of characters for generating the location identification code, wherein the first base of the location identification code is a total number of characters in the predetermined set of characters;

converting the location identification code to an index having a second base with the at least one programmable processor;

retrieving reference coordinates corresponding to the index from at least one of the one or more computer-readable storage mediums;

retrieving a location description based on the location identification code from at least one of the one or more computer-readable storage mediums;

displaying the location description on the electronic display of the interactive mapping system for validation by a system user; and

retrieving map data from at least one of the one or more computer-readable storage mediums using the reference coordinates and displaying the map data on the electronic display.

20. The method of claim 19, wherein the predetermined set of characters consists of consonants and numbers.
