3D Visualisation of Davis Station, Antarctica

GIS vs CAD:

The main component of the thesis involved creating a model of the terrain and the man made structures that lied upon it. As realism was a vital part of the project a software package was needed that would allow a model to be produced that resembled Davis Station. The following tables  highlight the limitations and benefits of the software packages for the purpose of creating a realistic visualisation for orientation purposes.

The Model used for the final visualisation was created in Autodesk 3ds max as realism was the overriding concern. The possibilities that modelling in a realistic GIS environment present is a very exciting future application.

Benefits

Limitations

Complex structures can be modelled

Images can not be georeferenced

Individual faces of objects can be modified and textured separately

Shapefile attribute data is lost when exported into Autodesk 3ds max

Contains a renderer and is capable of  quality animation

Model can not be animated smoothly if it is far from the origin

Benefits

Limitations

Terrain and structures are easily merged

Modelling capabilities are very limited

Images can be Georeferenced

Individual faces of an object can not be textured separately

Model is linked to attribute data

Does not have a renderer
