Geospatial Property Identifier System for Parcel Change Tracking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems lack mechanisms to link attributes of original parcels with changed parcels, leading to difficulties in tracking parcel changes over time and incorrectly categorizing structures within hazard zones, resulting in potential damage and loss of life.
Innovation Solution
A geospatial property identifier system generates unique identifiers based on geometric land and building information, allowing for the differentiation of parcels and structures, and linking property data across changes, enabling accurate hazard zone assignment and data deduplication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional systems use static parcel identifiers, then data storage is simple, but the system cannot track parcel changes over time or link original parcels with changed parcels
Solution Approach 1:
The patent implements dynamic parcel identifiers that automatically update when parcel boundaries change. The system compares current boundary coordinates with historical boundaries, detects changes exceeding a threshold, and generates new identifiers accordingly. This dynamic approach enables reliable tracking of parcel transformations while maintaining systematic organization through automated processes.
Solution Approach 2:
The patent introduces boundary coordinate data as an intermediary element between the parcel identifier and the parcel itself. By using geometric boundary information as the basis for generating identifiers, the system creates a reliable link between original and changed parcels without requiring complex manual tracking mechanisms.
2Measurement precision
If the system generates new identifiers for every boundary change, then tracking accuracy improves, but data redundancy and storage requirements increase
Solution Approach 1:
The patent employs a threshold-based parameter change detection mechanism that compares boundary coordinate differences against predetermined thresholds. Only changes exceeding the threshold trigger identifier regeneration, thereby achieving accurate tracking of significant parcel modifications while filtering out minor variations that would otherwise create unnecessary data redundancy.
Solution Approach 2:
The system applies different levels of identifier generation based on the nature and magnitude of boundary changes. By analyzing the specific characteristics of each change (size, location, significance), the system selectively generates new identifiers only where necessary, optimizing the balance between tracking precision and data efficiency.
3Measurement precision
If the system links multiple identifiers (parcel, structure, unit) hierarchically, then hazard zone categorization accuracy improves, but system complexity and data retrieval complexity increase
Solution Approach 1:
The patent implements a nested hierarchical structure where unit identifiers are contained within structure identifiers, which are in turn contained within parcel identifiers. This nesting approach enables precise hazard zone categorization by allowing queries to traverse from the most specific (unit) to the most general (parcel) level, while the systematic nesting actually simplifies data retrieval compared to independent identifier management.
Solution Approach 2:
The hierarchical identifier system serves multiple functions simultaneously: it enables hazard zone categorization, tracks parcel changes, maintains historical records, and supports various query types. By designing the identifier structure to be multi-functional from the outset, the system avoids the need for separate mechanisms for each function, thereby managing complexity efficiently.
4Loss of information
If the system stores historical boundary data for every parcel change, then data completeness improves, but storage requirements and processing time increase
Solution Approach 1:
The patent implements preliminary boundary validation and change detection mechanisms that assess whether stored historical data is sufficient before triggering full data archiving. By performing preliminary assessments, the system maintains data completeness for significant changes while avoiding redundant storage of minor variations, thereby optimizing the balance between information completeness and storage efficiency.

AI summary
A system that can generate unique identifiers for individual real estate parcels and/or individual structure(s) located on individual real estate parcels using geometric land and/or building information is described. For example, the system can obtain geographical coordinate information and/or topological information that defines a two-dimensional or three-dimensional boundary of a parcel. The system can then determine and assign a unique identifier to the parcel, where the unique identifier is based on the two-dimensional or three-dimensional boundary. As another example, the system can obtain geographical coordinate information and/or structure architectural plans that define a two-dimensional or three-dimensional boundary of a structure. The system can then determine and assign a unique identifier to the structure, where the unique identifier is based on the two-dimensional or three-dimensional boundary of the structure.
