Abstract

A computer-implemented geospatial and temporal data storage system and method provides access to geospatial and temporal data as it is associated with events and event-types, thereby assisting in forecasting occurrences of identifiable events and/or results based on signature and/or pattern matching.

Claims

1. A computer-implemented geospatial and temporal data storage system, comprising:

a geospatial database including geospatial data and a plurality of indices into the geospatial data;

a temporal database including temporal data and a plurality of indices into the temporal data; and

means for searching for and retrieving data from the geospatial and temporal databases.

2. The data storage system of claim 1 wherein the means for searching for and retrieving data includes programming that accepts requests for geospatially or temporally-referenced data, accesses the geospatial or temporal data from a medium upon which the geospatial or temporal data are stored and provides responses to the requests.

3. The system of claim 1 further including computer programming associated with the geospatial and temporal databases for determining whether to access the geospatial database or the temporal database depending upon a received request.

4. The system of claim 1 wherein the temporal database includes at least one index based upon trends.

5. The system of claim 1 wherein the temporal database includes at least one index based upon seasons.

6. The system of claim 1 wherein the temporal database includes at least one index based upon cycles.

7. The system of claim 1 wherein the temporal database includes at least one index based upon sequences.

8. The system of claim 1 wherein the temporal database includes at least one index based upon intervals.

9. The system of claim 1 further including an event-type database including event-type data and a plurality of indices into the event-type data, wherein the means for searching for and retrieving data from the temporal database includes an interface that accepts queries for event-type data.

10. The system of claim 9 wherein a plurality of events are stored, each having one or more elements of event-type data, temporal data and geospatial data.

11. A computerized method for detecting changes in event-type timing, comprising the steps of:

establishing and storing, in a geospatial and temporal data storage system, an original temporal signature for a given event type based on a determined likelihood associating the event type'"'"'s relative proximity and time of occurrence to a variable of interest (VOI) within a geospatial area of interest (AOI);

receiving temporal information pertaining to one or more subsequent events of the given event type within the AOI, including timing information for the one or more subsequent events;

classifying the received information as part of the original signature or as an outlier; and

upon the received information meeting or exceeding a pre-determined threshold for classification as an outlier, establishing and storing a reassessed signature for the given event type.

12. A computer-implemented method for providing an event-type storage system having geospatial and temporal elements, comprising:

providing an event-type database having event-type data, temporal data and geospatial data, and a plurality of indices into the event-type data, temporal data and geospatial data; and

providing means for searching for and retrieving data from the event-type, geospatial and temporal databases.

13. The method of claim 12 wherein the means for searching for and retrieving data includes programming that accepts requests for event-type, geospatially or temporally-referenced data, accesses the event-type, geospatial or temporal data from a medium upon which the event-type, geospatial or temporal data are stored and provides responses to the requests.

14. The method of claim 12 further including the step of providing computer programming associated with the event-type, geospatial and temporal databases for determining whether to access the event-type database, geospatial database or the temporal database depending upon a received request.

15. The method of claim 12 wherein the temporal database includes at least one index based upon trends.

16. The method of claim 12 wherein the temporal database includes at least one index based upon seasons.

17. The method of claim 12 wherein the temporal database includes at least one index based upon cycles.

18. The method of claim 12 wherein the temporal database includes at least one index based upon sequences.

19. The method of claim 12 wherein the temporal database includes at least one index based upon intervals.
