As cities grow more complex, the need for accurate, data-driven planning tools has never been greater. Digital twins and 3D modelling are transforming how we analyse, plan and manage urban environments. They support better decisions, more efficient infrastructure and more sustainable development.

This specialised course introduces the foundations of 3D digital modelling and spatial digital twins, combining theory with hands-on practice. You’ll useÌýtools like SketchUp, PostGIS and QGIS to create, manage and visualise 3D urban data.ÌýThrough practical exercises and guided learning, you’ll gain the skills to support smarter planning, analysis and communication in the built environment.

What will I learn?

Spatial digital twins have become essential in academia, government and institutions for planning, decision-making and management. This course introduces 3D digital models for the built environment, covering how to create, manage and visualise them. You’ll explore foundational theories and technical skills, including GIS, 3D modelling and database management and gain practical experience with tools like SketchUp, PostGIS and QGIS.

By the end of the course, you’ll have the knowledge and practical skills to work confidently with 3D digital tools in real-world urban contexts. Whether you're advancing in urban planning, architecture or smart city innovation, this course provides future-focused skills that will shape more efficient, sustainable and responsive cities.

How will I learn?

This course is delivered online across five modules and includes a mix of pre-recorded lectures, practical activities (practicums) and self-directed study. This flexible format allows you to engage with the content at your own pace while building applied skills throughout the course.

The total volume of learning is 25 hours.

Who should take this course?

The course will be relevant to students, researchers and professionals in urban planning, architecture, GIS and the built environment who want to develop practical skills in 3D modelling and spatial digital twins.

It is also designed for Government and industry practitioners involved in smart city planning, infrastructure and data-driven decision-making.
