Module: 3D GIS, City Models and Digital Twins

Lecture: Concepts of 3D modeling of the built environment

Lecture summary

This lecture provides the introduction to 3D geographical modelling and is possible to take without
previous knowledge of 3D GIS. It starts with several different concepts of 3D visualization and
explains how they differ according to area of usage. The student learns briefly about voxels models
and more deeply about creation of reality-mesh models, with real-world examples.

Learning outcomes

At the end of this lecture, the learner is expected to be able to:

Understand main concepts and different types of 3D geographical modelling
Understand principles of 3D raster / voxel models
Describe creation and advantages of reality-mesh models

Learning materials

This lecture consists of a slide-based presentation accompanied by a text document (presentation notes) that includes additional information on the slides.
