  2. Contents • Introduction (definition of HR, current HR sensors, main characteristics, technological alternatives) • Image quality, radiometric analysis, preprocessing • Geometric sensor models and sensor orientation • Automated DSM generation • DSM generation using SPOT-5 images • Reduction of DSM to DTM and quality analysis • Orthoimage generation and object extraction (mainly roads and buildings) • SRTM DTM • Conclusions and outlook
