Abstract: The history and recent development of photogrammetry and remote sensing are reviewed and analyzed firstly. Then the novel concept of "photogrammetric remote sensing" is put forward to meet the needs of accurate and fast processing of multi-source remote sensing images in the new era of big data and intelligent surveying and mapping. The new photogrammetric remote sensing discipline is the deep integration of the frontier theories and technologies of photogrammetry and remote sensing, and concentrates on solving the theories and technologies about simultaneously determine the geometric positions, physical attributes, semantic information and temporal changes of interested scenes and objects. Its theoretical and fundamental basis are photogrammetry, remote sensing, artificial intelligence, big data processing, and high-performance computation, etc. It will break through the current isolated status and serial technical route that photogrammetry mainly focuses on geometric processing, while remote sensing mainly focuses on semantic information extraction and inversion. It forms an innovation of the closed-loop fusion of semantic extraction and geometric processing. A novel geometric-semantic integrated processing framework is formed through the deep fusion of geometric model and spectral radiative and reflective information. Based on the proposed concept of photogrammetric remote sensing, this paper discusses the main scientific problems and related research and application fields, and then attempts to build a new theoretical and technical framework of integrated intelligent photogrammetric remote sensing processing of multi-source satellite images. Closed-loop fusion of semantic information extraction and accurate geometric processing has significantly improved the level of accuracy, automation and intelligence. The correctness and effectiveness of the proposed theory and methods are preliminarily verified by several practical applications.
