Audio Data Spatial Mapping via Surface Footprint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mapping service providers face challenges in efficiently searching and retrieving audio data associated with geographic locations, making it difficult to provide effective spatial querying and analytics.
Innovation Solution
A method and system that process audio data and metadata to determine location data, compute a surface footprint representing geographic areas or locations, and store associations between audio data and these footprints in a geographic database, enabling efficient retrieval and spatial querying of audio data based on location.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If audio data is stored with detailed location information, then spatial querying capability is improved, but data storage complexity increases
Solution Approach 1:
The patent segments location data into discrete geographic coordinates and audio data into separate records, then creates structured associations between them. This segmentation allows the system to query spatial information without retrieving entire audio datasets, reducing storage complexity while maintaining spatial querying capability.
Solution Approach 2:
The patent introduces an intermediary data structure that links audio data to location information through geographic coordinates. This intermediary layer acts as a bridge between the audio database and spatial query systems, enabling efficient location-based searches without directly coupling the audio storage and location data structures.
2Measurement precision
If location data is extracted and processed for every audio file, then spatial accuracy is improved, but processing time increases
Solution Approach 1:
The patent extracts and processes location data from audio files during the initial ingestion phase rather than during query operations. By performing location extraction preliminarily and storing the results with the audio metadata, the system achieves high spatial accuracy without incurring processing delays during actual queries.
Solution Approach 2:
The patent creates a simplified copy of location information (geographic coordinates) that can be quickly processed and stored separately from the full audio data. This copied location data serves as a lightweight reference that enables fast spatial queries without requiring repeated processing of the original audio content.
3Productivity
If a comprehensive geographic database is created to store all audio locations, then retrieval efficiency is improved, but database size increases
Solution Approach 1:
The patent extracts only the essential location components (geographic coordinates) from audio files and stores them in a streamlined database structure. By taking out only the necessary spatial information rather than storing complete audio files with embedded metadata, the system achieves efficient location-based retrieval while keeping database size manageable.
Solution Approach 2:
The patent implements a database structure where location data is stored with the specific quality and detail level appropriate for spatial querying needs. Rather than uniformly storing all possible audio attributes for every record, the system applies local quality by storing only the geographic coordinates and essential metadata needed for location-based retrieval, reducing overall database size while maintaining retrieval efficiency.

AI summary
An approach is provided for associating conversation and/or audio data with locations. The approach, for instance, involves processing audio data, metadata associated with the audio data, or a combination thereof to determine location data. The approach also involves computing a surface footprint based on the location data. The surface footprint indicates one or more of a geographic area or a plurality of locations associated with the audio data, the metadata, or a combination thereof. The approach further involves storing, in a geographic database, an association between the computed surface footprint and the audio data, the metadata, or a combination thereof.
