Entity display priority in a distributed geographic information system
View Patent ↗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.
1. A computer-implemented geographic information system (GIS) comprising:
a processor for executing program code; and
a non-transitory computer-readable storage medium storing program code executable to perform steps comprising:
receiving non-cartographic information about a plurality of geospatial entities, each geospatial entity having a geometry and located at a physical location, wherein the information is harvested from a plurality of websites, and wherein the information comprises an attribute of a description of the geospatial entity;
prioritizing the 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 non-cartographic information further comprises one of: quality of information available about the geospatial entity, and an attribute of a definition of the geospatial entity.
3. The system of claim 1 , wherein the non-cartographic information further comprises an indicator of the geospatial entity's popularity.
4. The system of claim 1 , wherein the non-cartographic information further comprises one of: an age attribute, a stature attribute, and an importance attribute.
5. The system of claim 1 , wherein the non-cartographic information further comprises 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 an entity of the plurality of entities comprises a geospatial entity defined in an on-line forum and wherein the ranking mechanism uses data generated in the on-line forum to determine the rank of the geospatial entity.
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 geospatial entity data, wherein the data is harvested from a plurality of websites and wherein the non-cartographic geospatial entity data comprises an attribute of a description of the geospatial entity and wherein each geospatial entity has a geometry and is located at a physical location;
determining a score by one or more processors for each of the geospatial entities based on the non-cartographic geospatial entity data;
ranking by the one or more processors the geospatial entities based on the scores; and
storing the ranked geospatial entities.
10. The method of claim 9 , wherein the non-cartographic geospatial entity data comprises data generated in a community forum.
11. The method of claim 9 , wherein the non-cartographic geospatial entity data comprises data associated with a user and further comprising using the ranked geospatial entities to generate a map for the user.
12. The method of claim 9 , further comprising selecting geospatial entities for a geographical display based on the rankings of the geospatial entities.
13. The method of claim 9 , further comprising providing the ranked geospatial entities to a map system configured to generate a map that includes ranked geospatial entities and unranked geospatial entities.
14. The method of claim 9 , further comprising selecting geospatial entities to include in navigation instructions based on rankings of the geospatial entities.
15. The method of claim 9 , further comprising selecting a geospatial entity to associate with an advertising term based on the geospatial entity's ranking.
16. The method of claim 9 , further comprising providing the ranked geospatial entity data to an application for generating a search result based on the ranked geospatial entity data.
17. The method of claim 9 , wherein determining the scores is performed responsive to user instructions for providing personalized geospatial entity rankings.
18. The method of claim 9 , wherein the non-cartographic information further comprises at least one of: quality of information available about the geospatial entity and an attribute of a definition of the geospatial entity.
19. The system of claim 1 wherein the non-cartographic geospatial entity data comprises data associated with a user and further comprising using the ranked geospatial entities to generate a map for the user.
20. The system of claim 1 wherein the program code is further executable to select geospatial entities for a geographical display based on the rankings of the geospatial entities.
