3D terrain analysis with grid planning
Challenge
Areas had to be measured directly on real 3D terrain and regular grids derived from them. Planning in plan view distorts distances and areas.
Technology
- TypeScript
- React
- CesiumJS
- Web Worker
- GDAL
Requirements
- Draw areas directly on 3D terrain
- Measure slope, area and perimeter
- Generate grids in the actual terrain plane
- Assess the accuracy of the elevation data
- Smooth interface even during heavy analysis
Approach
- 01Analysis services independent of the interface
- 02Terrain sampling for slope and in-plane gridding
- 03Heavy computation in web workers
- 04Chunked upload of custom terrain data with coordinate extraction
