3D-ARCH is a series of international workshops which started in 2005 in Venice and move throughout the years to Zurich (2007), Trento (2009, 2011, 2013), Avila (2015) and Napflio (2017), organized as an ISPRS and CIPA event.

The main focus of the workshop is to discuss steps and processes for smart 3D reconstruction, modelling, accessing and understanding of digital environments from multiple data sources. Topics include:

• Multi-source data and multi-sensors approaches
• Low-cost sensors and open-source algorithms for terrestrial 3D modeling
• Automation in data registration
• Image matching and 3D reconstruction
• Point cloud analysis
• 4D modelling
• Procedural modeling
• Accuracy requirement and assessment in 3D reconstructions
• 3D applications in terrestrial and underwater environments
• Virtual and Augmented Reality applied to the visualization and conservation of complex architectures and heritage
