3D Map Projection from 2D Documents Using Geospatial Translation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Two-dimensional map projections distort data, making it difficult to compare relative sizes or distances, and true 3D map data is not typically compatible with document-based applications, limiting the ability to view geospatial data in three dimensions.
Innovation Solution
A system and method for rendering true three-dimensional views of two-dimensional maps by importing a 2D image, extracting geospatial features, and translating them into 3D data, using geospatial information to project the map onto a 3D model of the Earth, allowing for accurate representation of relative sizes and locations.

Engineering Contradiction Analysis
1Ease of manufacture
If two-dimensional map projections are used, then the map can be displayed on flat surfaces, but data distortion occurs making it difficult to compare relative sizes or distances
Solution Approach 1:
The patent transitions from two-dimensional map projections to three-dimensional virtual globe representations. By displaying geospatial data on a 3D spherical model rather than flattening it onto a 2D plane, the system eliminates projection distortions while maintaining accurate relative sizes and distances of geographic features.
2Measurement precision
If true three-dimensional map data is created, then accurate geospatial visualization is achieved, but compatibility with document-based applications is lost
Solution Approach 1:
The patent introduces a virtual globe as an intermediary representation that bridges 3D geospatial accuracy and 2D document compatibility. The system renders the 3D virtual globe onto a two-dimensional display surface, allowing accurate geospatial data to be viewed within conventional document-based applications without requiring specialized 3D software.
3Measurement precision
If three-dimensional virtual globe rendering is implemented, then accurate geospatial data visualization is achieved, but computational complexity increases
Solution Approach 1:
The patent pre-computes and stores geospatial data in a structured format suitable for virtual globe rendering. By preparing the data beforehand with proper coordinate transformations and projections, the system reduces real-time computational requirements during rendering, making complex 3D visualizations achievable on standard hardware.

AI summary
Systems, methods, and computer-readable storage media for generating 3D views of 2D images are disclosed. Image data representing a 2D map may be included in an input document in a portable document format, along with embedded geospatial information related to the map. A document-based 3D translator may extract image data and other information from the input document and may translate the image into a map projected on a 3D model of the Earth's surface, using embedded location and/or extent information. Additional information may be projected on the map image or displayed as a height, texture, or color, or as separate, anchored, or floating text. Image data representing the 3D view may be output to the same or a different document file. The methods may be implemented in a system comprising a CPU and/or a GPU, and/or as program instructions, stored on computer-readable media, executable by the CPU and/or GPU.
