A Comprehensive Examination of Satellite Stereo Triplet Image Matching for Digital Elevation Model (DEM) Generation

Satellite-derived Digital Elevation Models (DEMs) are of utmost significance in a wide range of applications, such as analysing terrain, urban planning, navigation and transportation, managing disasters, hydrological modelling, and monitoring natural resources. These applications collectively contribute to enhancing our comprehension, management, and planning of Earth's surface and its valuable resources. This research paper delves into exploring diverse methods and satellites employed for automatically generating DEMs from satellite stereo triplet images. The study primarily emphasises the importance of comprehending satellite image geometry, integrating suitable matching techniques, and developing open-source workflows to enhance the precision of automatically generated DEMs. Moreover, it aims to furnish valuable insights for future studies in this domain.
