Global Reference Grid Attribute Mapping for Vector Overlap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional GIS and BIM applications struggle with efficiently tracking changes to surfaces, managing material shifts, documenting material flows, detecting usage conflicts, and determining obstacle-free areas due to the isolation of local grids, leading to inefficiencies and high data processing complexity.
Innovation Solution
A computer-implemented method using a global reference grid with uniquely identifiable grid elements, independent of vector objects, to assign attributes to grid elements within a single database, enabling consistent data management and reduced memory usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If local grids are used for each vector object in conventional GIS and BIM applications, then spatial data can be managed for individual objects, but data processing complexity increases and memory usage becomes inefficient due to isolation of local grids
Solution Approach 1:
The patent merges multiple isolated local grids into a single global reference grid that covers the entire working area. This global grid serves as a unified framework for all vector objects, eliminating the need for separate local grids and their associated complexity. The merging principle directly resolves the contradiction by consolidating data structures to improve processing efficiency while reducing overall system complexity.
Solution Approach 2:
The global reference grid serves multiple functions simultaneously: it acts as a spatial indexing structure, a coordinate reference system, and a framework for managing all vector objects in the database. This universal structure replaces the need for multiple specialized local grids, thereby improving productivity while reducing the complexity of managing multiple separate grid systems.
2Adaptability or versatility
If multiple local grids are created for different vector objects, then each object can have its own spatial reference, but memory usage increases due to redundant data storage
Solution Approach 1:
By merging multiple local grids into one global reference grid, the patent eliminates redundant storage of grid structures and their metadata. The global grid is stored once and shared across all vector objects, significantly reducing memory consumption while maintaining the ability to manage diverse spatial data through the same unified structure.
Solution Approach 2:
Instead of creating actual copies of grid structures for each vector object, the patent uses references to the single global grid. Vector objects store only their geometric data and reference the global grid for spatial context, avoiding the memory overhead of duplicating grid structures while preserving spatial reference capabilities.
3Reliability
If local grids are isolated for each vector object, then object-specific spatial management is enabled, but tracking changes and detecting conflicts becomes inefficient
Solution Approach 1:
The global reference grid provides a unified spatial framework that enables efficient tracking of changes across all vector objects. Since all objects reference the same grid, changes can be monitored systematically at the grid level, improving productivity in change tracking while maintaining data consistency through the centralized reference structure.
Solution Approach 2:
The global reference grid structure enables systematic feedback mechanisms for detecting conflicts and tracking changes. By monitoring the global grid state, the system can identify conflicts between overlapping vector objects and track changes efficiently, thereby improving productivity while ensuring data consistency through centralized control.

AI summary
A method detects a spatial arrangement of a physical object by assigning an attribute to a selection of uniquely identifiable global grid elements of a reference grid network. The method includes providing a global reference grid network with a geographical reference point defined vector-object-independently and global grid elements, which are adjacent to one another without overlap and are uniquely identifiable within the global reference grid network and are georeferenced with regard to a provided reference coordinate system, providing a vector object with at least one vertex, to which a geographical coordinate of the geographical reference coordinate system is assigned, determining and selecting those global grid elements that overlap with the vector object, and assigning an object attribute linked with the vector object or a further attribute to the grid elements selected and storing the selected grid elements with assigned attributes.
