Geospatial Information System With Overlap Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing geospatial information systems are limited in their ability to accommodate diverse user needs and applications, failing to effectively manage and display a wide range of geospatial information types.
Innovation Solution
A geospatial information system that allows users to upload and manage various types of geospatial content, including orthoimages, moving images, 3D models, and labels, while enabling the association of these contents with geospatial coordinates and time stamps, and providing flexible display options such as overlap and divisional formats.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a geospatial information system displays flood-depth layers with specific color coding for disaster prevention, then it effectively supports flood damage measures, but it cannot accommodate diverse user needs and different types of geospatial information
Solution Approach 1:
The system implements a standardized data structure with common elements (geospatial coordinates, time information, attribute data) that can accommodate multiple types of geospatial information including flood-depth data, orthoimages, 3D models, and other geographic data. This universal framework allows the same system to serve both disaster prevention purposes and diverse user needs without requiring separate specialized systems
2Device complexity
If the system manages only specific types of geospatial information, then it maintains simplicity in data management, but it cannot manage wider types of geospatial information
Solution Approach 1:
The system segments geospatial information into standardized components: position information (coordinates), time information (timestamps), and attribute information (descriptive data). This segmentation allows diverse geospatial data types to be managed through a unified structure, maintaining simplicity while expanding capability to handle multiple information types including flood data, images, models, and labels
3Ease of operation
If the system displays geospatial information without time association, then the display process is simple, but it cannot provide visualization that incorporates both geospatial position and time
Solution Approach 1:
The system adds a time dimension to traditional geospatial display by associating timestamp information with each geospatial data element. This transforms the display from static 2D spatial representation to dynamic 4D visualization (3D space + time), enabling users to view changes over time while maintaining the underlying simple display mechanism through standardized data structures

AI summary
Provided is a geospatial information system which can be applied to a wide range of different usages or user needs. The geospatial information system 1 includes: a database 11; a content registration unit 13 which registers, in the database, geospatial content uploaded from a user; and a content display unit 19 which provides, to a user terminal, a geospatial information screen on which the registered geospatial content is displayed. The registrable geospatial content includes a mono image, an orthoimage, a moving image, three-dimensional model data, analysis result data thereof, and the like. In the geospatial information screen, an overlap display and a divisional display may be selected. For the overlap display, content display arrangement is in the order of a map, an orthoimage, and other content icons from the rear surface toward the front surface.
