Display and Management of Geomatics Research Data
- Timothy Daniel Trewartha
- Michiel Johan Baird
- Started by the UCT Department of Geomatics in 2004
- Aims to preserve cultural heritage by documenting sites and producing laser scanned models
- Over 100 models of sites in various African countries including South Africa, Zimbabwe, Kenya and Tanzania
- Some of the models are very large and contain billions of points
- Fast-growing volume of data
- Difficulty in storing the data
- Difficulty with viewing the large models in real-time
- Data locality issues
- Large number of users interact with the data
- To enable viewing of the large 3D models at interactive frame rates we will implement a hierachical multi-resolution data structure
- A server with a large amount of storage will be procured; this will be used to store the models and GIS data, and support the core functionalities of the solution.
Division of Work
- Tim will be implementing the hierachical datastructure to enable real-time interaction with the large 3D models.
- Michiel will be implementing a Scientific workbench that is specialised for GIS research. This will pay special attention to data movement and intergration with existing GIS tools.
