  1. 13th International Scientific and Technical Conference From Imagery to Map: Digital Photogrammetric Technologies Trends in Digital Photogrammetric Workstations Andrey Sechin Scientific Director, Racurs September 2013, Fontainebleau, France

  2. What Drives DPW Development? • New sensors – aerial cameras, lidars, satellites, gps-imu, … • Computer technology • New Algorithms • Network technologies • User experience and wishes

  3. New sensors Satellite imagery: Higher productivity, large blocks Aerial survey: high overlap, big color depth (>8 bits per channel), special oblique cameras, lidars

  4. Computer technologies 64-bit computing Multicore CPU multithreading Clusters CUDA, MIC,… Operating system – Windows 7 Home Premium 64 Processor - 3rd Generation Intel (R) Core (TM) i5-3330 quad-core processor [3.0GHz, 6MB Shared Cache] Memory – 6GB DDR3-1333MHz SDRAM [2 DIMMs]

  5. New algorithms Computer Vision –> algorithms Pattern recognition –> automation 3D

  6. 3D • 3D geoportals, • 3D GIS • … Do we need 3D point clouds? Automatic 3D points conversion to vector objects: roofs, roads,…

  7. Network technologies DPW GEO Database/GEO Portal • Cloud storage • Software as a service • Client-server architecture

  8. User experience

  9. Conclusions • Oblique cameras and images • 64-bit software architecture • Cluster computing • Multithreading & multiprocessing • Automation: Point clouds -> vector objects • DPW & GEO Database/Portal integration • Client-Server networking

  10. Thank you for attention
