SNAP+: Preserving the Past, Training for the Future - Photogrammetry in Heritage and Adult Learning

Abstract

This article presents the SNAP+ project (Photogrammetry Aided Surveying in Heritage Management), a KA220-ADU Cooperation Partnership in Adult Education co-funded by the Erasmus+ programme. The project responded to a clear need identified at the European level: the lack of comprehensive, accessible, and high-quality didactic materials on photogrammetry and its wide application in architectural practice and heritage management. Special emphasis was placed on creating digital, illustrated, animated, interactive, and multilingual content tailored for adult learners. The main goal of SNAP+ is to deliver robust online learning resources in photogrammetry, using digital and interactive content to teach best practices in surveying and the effective use of captured data. The project implemented four field surveys in rural or disadvantaged regions across Europe (Portugal, Hungary, Romania, and Slovenia), collecting raw data later transformed into multiple representational products, including interactive 3D models, spherical panoramas, 2D architectural drawings, and BIM models. These outcomes form the core content of a comprehensive Digital Educational Handbook, the project's main learning tool. In addition, an online Educational Platform was developed to host all project results, including interactive quizzes for self-assessment and knowledge reinforcement. SNAP+ enhances the availability of quality learning opportunities for students of architecture and heritage management and adult learners, promoting digital transformation, and supporting pathways for professional reskilling. By bridging technology and heritage, the project helps popularize photogrammetry not only as a documentation tool but also as a viable profession within architecture and heritage fields.
