Spatial digital twins succeed or fail based on whether BIM data can perform in GIS at scale. In this webinar, you will learn practical, repeatable approaches for preparing IFC data so it can be used confidently across GIS workflows for geospatial analysis, asset context, and operational consumption.

Drawing from the buildingSMART International Porto Summit session, created by Daniel Chantlos and David Alvarez, we will cover common roadblocks such as geometry bloat, rendering performance, coordinate ambiguity, and information loss, then focus on standards-aligned principles to optimize and georeference IFC for downstream GIS platforms.

You will see how “purpose drives preparation” in practice: defining the business objective, filtering unnecessary detail, choosing the right GIS delivery format (including building scene layers and 3D object feature layers), and preparing content for web and operational experiences such as scene viewing and custom apps.
