Benefits of technology

This patent describes a system that allows access to geological information. It generates an index of information and identifiers that correspond to different geographical areas. Users can then use a query to get information that is specific to their current location. This system also includes a method and computer program product for accessing geological information in a similar way.

Problems solved by technology

These systems typically produce paper reports that take hours or days to compile.
This limits the usefulness of the reports to answering predetermined questions.

Embodiment Construction

[0015]Present invention embodiments relate to indexing information in a geographic information system (GIS). In one embodiment, geographic information is associated to predefined regions, and an index of the information is built. Information is represented in the index in manners that support searching, aggregation, and drill-down of geographic and non-geographic dimensions. For example, the predefined regions be may represented by string values (e.g., using Geohash or other encoding). Likewise, links between levels of hierarchical dimensions (e.g., categories and sub-categories) may be encoded in string fields. One aspect of a present invention embodiment includes a user interface that reacts quickly to a user's interactive selection of filter criteria across multiple data dimensions as a result of fast query processing using the index.

[0016]An example environment for present invention embodiments is illustrated in FIG. 1. Specifically, the environment includes one or more data sou...

Abstract

According to one embodiment of the present invention, a system provides access to geographic information. The system generates an index including information and one or more identifiers each indicating a corresponding geographic area pertaining to the information. The system processes a query against the index to provide information aggregated for corresponding geographic areas. Embodiments of the present invention further include a method and computer program product for providing access to geographic information in substantially the same manners described above.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a continuation of U.S. patent application Ser. No. 14 / 198,787, entitled “INDEXING GEOGRAPHIC DATA” and filed Mar. 6, 2014, the disclosure of which is incorporated herein by reference in its entirety.BACKGROUND[0002]1. Technical Field[0003]Present invention embodiments relate to a geographic information system (GIS), and more specifically, to indexing geographic-related information, including hierarchical attributes, in a manner that facilitates rapid access and display.[0004]2. Discussion of the Related Art[0005]Managers in law enforcement organizations use computer statistics systems to monitor activity in areas under their jurisdiction over an interval of time (e.g., the past twenty-four hours) and compare that activity to previous times (e.g., the previous week, month, year, etc.). These systems typically produce paper reports that take hours or days to compile. This limits the usefulness of the reports to answering...
