Photogrammetric Perspectives on Challenges/developments in Mapping from Very High Resolution Imaging Satellites

چکیده
Photogrammetric mapping has moved from its classical objective, which is the process of reconstructing objects from analog frame cameras to more contemporary objectives such as automatic generation of spatial and descriptive information from digital imagery. The advent of Very High Resolution (VHR) imaging satellites opens new challenges and potentialities to geo-spatial mapping community, especially when considering the integration of VHR satellite imagery and other types of data. This paper is focusing on recent photogrammetric development in the field of VHR imaging satellites. The following sections briefly present some of the challenges in photogrammetric mapping from VHR imaging satellites.

متن کاملPotential and Shortcoming of Small Satellite for Topographic Mapping
High resolution mapping systems follow the trend to smaller ground sample distances (GSD) making use of the best technology available at the given time. From the 80 m GSD of ERTS in 1972, the GSD now approached 1 m and even less for civil applications. Mass and power consumption of spacecrafts and imaging instruments follow similar trends in conjunction with the immense improvements in very div...
