Geographic Data Indexing for Rapid Law Enforcement Query Processing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current geographic information systems (GIS) used in law enforcement organizations are limited by the time-consuming process of compiling paper reports, which hinders the ability to rapidly access and analyze activity data across different time intervals and geographic areas.
Innovation Solution
A system that indexes geographic information using predefined regions and a reverse index, allowing for fast query processing and aggregation of data, enabling quick access and visualization of geographic and non-geographic dimensions through a user-friendly interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If paper reports are compiled manually, then comprehensive geographic information can be collected, but the time required to access and analyze the data increases significantly
Solution Approach 1:
The patent applies preliminary action by pre-computing and storing aggregated geographic statistics for multiple time intervals and geographic areas in an automated fashion before queries are made. The system pre-calculates crime statistics, incident counts, and other metrics for various geographic regions and time periods, storing them in an optimized format that enables rapid retrieval without manual compilation when reports are requested.
2Productivity
If automated systems are implemented to reduce report compilation time, then data access speed improves, but system complexity increases
Solution Approach 1:
The patent applies segmentation by dividing the geographic area into predefined regions and organizing data by geographic area, time interval, and crime type. The system segments the monolithic report generation task into smaller, independent computational units that can be pre-calculated and stored separately, then quickly assembled when reports are requested. This modular approach reduces system complexity while improving productivity.
3Measurement precision
If detailed geographic data is stored for all areas and time periods, then query accuracy improves, but data storage requirements increase
Solution Approach 1:
The patent applies local quality by storing detailed geographic data only for specific predefined regions and time intervals where it is actually needed for queries. Rather than uniformly storing all possible data combinations across the entire geographic area, the system selectively maintains detailed information for regions and time periods that have query relevance, optimizing the balance between query accuracy and storage requirements.

AI summary
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.
