3D-ARCH is a series of international workshops organized under the umbrella of ISPRS and CIPA. 

3D-ARCH started in 2005 in Venice and move throughout the years to Zurich (2007), Trento (2009, 2011, 2013), Avila (2015), Nafplio (2017), Bergamo (2019), Mantua (2022) and Siena (2024).

The main focus of the 11th edition is to discuss investigations, steps and processes for smart 3D reconstruction, modelling, accessing and understanding of digital environments from multiple data sources. 

Topics include:

• Low-cost sensors and open-source algorithms for terrestrial 3D modelling

• Fusion of multi-source and multi-sensors terrestrial data

• Research in 3D/4D survey and modelling

• Automation in terrestrial data processing

• Image matching, Multi-View Stereo (MVS) and 3D reconstruction

• Point cloud processing, semantic enrichment and analysis

• 3D reconstruction and modelling with AI methods (including LLMs), NeRF and Gaussian Splatting 

• Accuracy requirement and assessment

• Virtual and Augmented Reality for complex architectures and heritage
