Summary: Archives of historical aerial photographs can be used to augment long-term records of quantitative landscape change, but manual processing tasks hinder efficiency. We developed an automated method to generate high-resolution DEMs and orthoimages from historical images without manual GCP selection. Our method corrects camera position errors and produces accurate georeferenced products, regardless of camera configuration or terrain characteristics.

Summary: The application of advanced photogrammetry and the integration of cross-sourced maps of historic cityscapes contribute to a thorough understanding of our surrounding. This research in Portugal utilized remote surveys, analysis of building dossiers, and onsite surveys to study traditional building typology. By virtually reconstructing two 16th century timber-framed facades, insights were gained into the past and present state of the buildings. The study emphasizes the importance of integrating different tools and databases for a more sensitive heritage management.

Summary: This study proposes a workflow for fully automatic orientation of historical urban images, utilizing a neural network for feature extraction and nearest neighbor matching, as well as vanishing point detection for estimating camera principal distance. Results show that the proposed method outperforms other SfM tools and is planned for knowledge transfer in cultural heritage applications.

Summary: This article discusses the challenge of understanding and connecting historical territorial imagery collections through content-based image retrieval, introducing the alegoria benchmark which contains mixed multi-date vertical and oblique aerial digitized photography with modern street-level pictures. The study proposes to address the low-data, heterogeneous image retrieval problem by reviewing ideas and methods, comparing state-of-the-art descriptors, and introducing a new multi-descriptor diffusion method to exploit their strengths. Results highlight the benefits of combining descriptors and the trade-off between absolute and cross-domain performance.

Summary: Monitoring Alpine glaciers over long periods is crucial for tracking climate change, with historical aerial images proving to be valuable resources for studying past glacier evolution. By utilizing structure from motion techniques and combining digital surveys from different time periods, the evolution of the Belvedere Glacier was analyzed with high resolution and geometrical accuracy. The integration of datasets spanning from 1977 to 2019 highlights the importance of historical photogrammetric datasets in glaciological studies.
