Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The collection and processing of geographic data face challenges due to the lack of standardized codes for geographic features, leading to difficulties in data collection and interpretation, as well as the incompatibility between field data collection and office processing applications, resulting in inefficient data exchange and increased human error.
Innovation Solution
A method that automatically identifies attribute data from media files and uses a configuration file to define how these attributes are displayed, enabling consistent visualization of geographic features and attributes across different applications, thereby facilitating collaborative data display and reducing human error.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If ASCII codes are used to minimize computing resource usage, then memory and data storage are reduced, but data interpretation becomes difficult and requires memorization of non-standardized codes
Solution Approach 1:
The patent introduces an intermediary component (code translation module or lookup table) that converts ASCII codes to descriptive feature names. This intermediary allows the system to store compact ASCII codes for memory efficiency while providing human-readable descriptions for easy interpretation, thus resolving the contradiction between storage minimization and operational ease.
Solution Approach 2:
The patent applies preliminary action by pre-defining standardized code sets and creating translation mappings between ASCII codes and descriptive names before data collection. This preparation eliminates the need for field workers to memorize codes and enables automatic translation during data processing, improving both storage efficiency and interpretation ease.
2Ease of manufacture
If field data collection and office processing applications are developed as stand-alone applications, then application development is simpler, but data exchange becomes inefficient and incompatible
Solution Approach 1:
The patent implements a universal data exchange standard that enables both field collection and office processing applications to operate independently while maintaining compatibility. The standardized format allows either application to generate and process data files from the other, providing multi-functionality that resolves the contradiction between development simplicity and exchange efficiency.
Solution Approach 2:
The patent changes the data format parameters to a standardized structure that is natively compatible between applications. By standardizing attributes, data types, and file formats, the system eliminates conversion requirements while maintaining independent application development, thus improving data exchange efficiency without complicating development.
3Loss of information
If manual lookup of ASCII codes is required, then data can be interpreted, but time consumption and human error increase
Solution Approach 1:
The patent implements self-service by enabling the system to automatically translate and interpret ASCII codes without human intervention. The standardized format includes built-in translation capabilities that automatically convert codes to descriptive names during data processing, eliminating manual lookup and reducing both time consumption and error rates.
Solution Approach 2:
The patent incorporates feedback mechanisms where the system automatically validates and translates codes during data entry and processing. This real-time feedback provides immediate interpretation of ASCII codes, eliminating delays associated with manual lookup and reducing errors through automated verification.

AI summary
Embodiments of the present invention recite a method for extracting attribute data from a media file. In one embodiment, an attribute of a geographic feature, which is described in at least one media file, is automatically identified. A configuration file is then accessed which defines how the attribute is to be displayed by an office application. The attribute is then displayed in a manner consistent with the configuration file.
