Virtual 3D Landscapes

Geo-data sources serving the generation of virtual 3D models in terms of geometric and visual surface properties are progressively available. The  generation of a virtual landscape model, however, is no standard process. Different use context and related design options of representations of existing or past environments will be presented. Central is an introduction to a comprehensive workflow leading from established geo-data sources (e.g. aerial imagery, digital terrain model) to a textured 3D model. Upgrades of heterogeneous primary data to a 3D model will be treated not only in theory, but essential processing steps will have to be performed by each participant.

The module:

• presents concepts of virtual 3D landscape models
• exemplifies different use context and implications on the model design
• shows potential input data sources
• discusses consistency demands within and among input sources
• offers a comprehensive workflow as an example
• demonstrates collaborative use of different software products
• guides practical implementation.

Intended Learning Outcomes:

At the end of the module students are able to

• remember applications of virtual 3D landscape models
• consider the range of design options
• choose suitable input data for 3D landscape models
• understand necessity of quality and consistency control
• produce 3D content of moderate complexity
• combine 3D content into a simple model.
