Announcement on CATCON 9: Call for Initial Evaluation Submissions
Computer Assisted Teaching Contest (CATCON)
What is CATCON?
CATCON is the name of a software contest organized by ISPRS. The main objective of the contest is to promote the development and dissemination of effective and user-friendly, open-source and preferably non-commercial software.
When is CATCON?
The competition will take place during the ISPRS Congress in Toronto. Day and time to be determined and communicated later with the final program of the congress.
Who can participate?
Any participant registered and admitted for an ISPRS Congress can submit a proposal and preliminary work for CATCON. The contest is open to individuals and teams. Each group can only submit one proposal. Software, which was presented at one Congress, can only be presented again at another Congress after having undergone substantial changes.
What is the prize?
There are three prizes: Gold award (3.000,- SFr.), a Silver Award (2.500,- SFr.) and a Bronze Award (1.500,- SFr.) and a certificate. Sponsored by The ISPRS Foundation.

The U. V. Helava Award – Best Paper 2025 announced
Congratulations go to Tao Sunb, Yan Hao, Shengyu Huang, Silvio Savarese, Konrad Schindler, Marc Pollefeys and Iro Armeni for their paper Nothing Stands Still: A spatiotemporal benchmark on 3D point cloud registration under large geometric and temporal change which was chosen as the 2025 Best Paper for the current evaluation period. The paper was published ISPRS Journal of Photogrammetry and Remote Sensing, Volume 220, February 2025, Pages 799-823. https://doi.org/10.1016/j.isprsjprs.2025.01.010
A New Benchmark for Large-Scale Point Cloud Registration: WHU-TLS
Registering large-scale point clouds is fundamental for applications ranging from 3D modeling and robotics to forestry and heritage conservation. Yet, existing datasets often face key issues: they either lack the scale and environmental diversity needed for real-world scenarios, or they do not provide sufficient variations in overlap, point density, and clutter. WHU-TLS overcomes these limitations by providing a massive, highly diverse collection of Terrestrial Laser Scanning (TLS) point clouds across varied environments, paired with reliable ground-truth transformations for precise algorithm evaluation.
