Abstract

A system for ranking geospatial entities is described. In one embodiment, the system comprises an interface for receiving ranking data about a plurality of geospatial entities and an entity ranking module. The module uses a ranking mechanism to generate place ranks for the geospatial entities based on the ranking data. Ranked entity data generated by the entity ranking module is stored in a database. The entity ranking module may be configured to evaluate a plurality of diverse attributes to determine a total score for a geospatial entity. The entity ranking module may be configured to organize ranked entity data into placemark layers.

Claims

1. A computer-implemented geographic information system (GIS), including a processor and memory, comprising:

a network interface to receive non-cartographic information about a plurality of geospatial entities, each geospatial entity defined in an on-line forum and each geospatial entity having a geometry and located at a physical location, wherein the information is generated in the on-line forum;

a database to store the non-cartographic information; and

a ranking module configured to prioritize a plurality of geospatial entities for display on a map using the non-cartographic information and according to a ranking mechanism.

2. The system of claim 1, wherein the ranking module is further configured to prioritize the geospatial entities for display using one of:

quality of information available about the geospatial entity, an attribute of a description of the geospatial entity, and an attribute of a definition of the geospatial entity.

3. The system of claim 1, wherein the ranking module is further configured to prioritize the plurality of geospatial entities for display using an indicator of the geospatial entity'"'"'s popularity.

4. The system of claim 1, wherein the ranking module is further configured to prioritize the plurality of geospatial entities for display using one of:

an age attribute of the geospatial entity, a stature attribute of the geospatial entity, and an importance attribute of the geospatial entity.

5. The system of claim 1, wherein the ranking module is further configured to prioritize the plurality of geospatial entities for display using a relationship of a geospatial entity to its place in a hierarchy of geospatial entities.

6. The system of claim 1, wherein an entity of the plurality of entities comprises a collection of geospatial objects and wherein the priority of the entity is determined responsive to a characteristic of the collection of geospatial objects.

7. The system of claim 1, wherein the ranking mechanism uses data harvested from a website about a geospatial entity to determine the geospatial entity'"'"'s priority.

8. The system of claim 1, wherein the ranking mechanism determines a geospatial entity'"'"'s priority from a combination of weighted data from a plurality of meta attributes of the geospatial entity.

9. A computer-implemented method for ranking geospatial entities, the method comprising:

receiving non-cartographic information about a plurality of geospatial entities, each geospatial entity defined in an on-line forum and each geospatial entity having a geometry and located at a physical location, wherein the information is generated in the on-line forum;

storing the non-cartographic information; and

prioritizing a plurality of geospatial entities for display on a map using the non-cartographic information and according to a ranking mechanism.

10. The method of claim 9, wherein prioritizing the geospatial entities for display further comprises prioritizing the plurality of geospatial entities for display using one of:

quality of information available about the geospatial entity, an attribute of a description of the geospatial entity, and an attribute of a definition of the geospatial entity.

11. The method of claim 9, wherein prioritizing the geospatial entities for display further comprises prioritizing the plurality of geospatial entities for display using an indicator of the geospatial entity'"'"'s popularity.

12. The method of claim 9, wherein prioritizing the geospatial entities for display further comprises prioritizing the plurality of geospatial entities for display using one of:

an age attribute of the geospatial entity, a stature attribute of the geospatial entity, and an importance attribute of the geospatial entity.

13. The method of claim 9, wherein prioritizing the geospatial entities for display further comprises prioritizing the plurality of geospatial entities for display using a relationship of a geospatial entity to its place in a hierarchy of geospatial entities.

14. The method of claim 9, wherein an entity of the plurality of entities comprises a collection of geospatial objects and wherein the priority of the entity is determined responsive to a characteristic of the collection of geospatial objects.

15. The method of claim 9, wherein the ranking mechanism uses data harvested from a website about a geospatial entity to determine the geospatial entity'"'"'s priority.

16. The method of claim 9, wherein the ranking mechanism determines a geospatial entity'"'"'s priority from a combination of weighted data from a plurality of meta attributes of the geospatial entity.

17. A computer program product, comprising:

a non-transitory machine-readable storage medium having computer readable program code embodied therein for ranking geospatial entities comprising computer readable program code to;

receive non-cartographic information about a plurality of geospatial entities, each geospatial entity defined in an on-line forum and each geospatial entity having a geometry and located at a physical location, wherein the information is generated in the on-line forum;

store the non-cartographic information; and

prioritize a plurality of geospatial entities for display on a map using the non-cartographic information and according to a ranking mechanism.

18. The computer program product of claim 17, further comprising computer readable program code to prioritize the geospatial entities for display using one of:

quality of information available about the geospatial entity, an attribute of a description of the geospatial entity, and an attribute of a definition of the geospatial entity.

19. The computer program product of claim 17, further comprising computer readable program code to prioritize the plurality of geospatial entities for display using an indicator of the geospatial entity'"'"'s popularity.

20. The computer program product of claim 17, further comprising computer readable program code to prioritize the plurality of geospatial entities for display using one of:

an age attribute of the geospatial entity, a stature attribute of the geospatial entity, and an importance attribute of the geospatial entity.

21. The computer program product of claim 17, further comprising computer readable program code to prioritize the plurality of geospatial entities for display using a relationship of a geospatial entity to its place in a hierarchy of geospatial entities.

22. The computer program product of claim 17, wherein an entity of the plurality of entities comprises a collection of geospatial objects and wherein the priority of the entity is determined responsive to a characteristic of the collection of geospatial objects.

23. The computer program product of claim 17, wherein the ranking mechanism uses data harvested from a website about a geospatial entity to determine the geospatial entity'"'"'s priority.

24. The computer program product of claim 17, wherein the ranking mechanism determines a geospatial entity'"'"'s priority from a combination of weighted data from a plurality of meta attributes of the geospatial entity.
