From Beijing 2008 to Melbourne 2012 to Prague 2016 - Trends in Photogrammetry and Remote Sensing – RACURS Conference 2013 in Fontainebleau, France September 23 – 26, 2013 Presentation by Gottfried Konecny Leibniz University Hannover, Germany
Since the foundation of ISPRS in 1910 , 22 International Congresses • in Photogrammetry and Remote Sensing took place ; now they are • scheduled every 4 years • These Congresses document the progress of the discipline • Progress is measured by 3 indicators: • - tasks • - traditions • - tools • The tasks remained unchanged since 1850 photogrammetry began • - to record, interpret and measure the environment by images, • - this was required to obtain local, regional and global geoinformation, • too costly and too time consuming to obtain by other means • Mapping became of such relevance around 1900, that a mapping profession was created 1910, the tradition of photogrammetry; but ISP(RS) already had • 1910 had a section of „non-topgraphic photogrammetry“.
While photogrammetry still is considered as a geodetic discipline, it continues • to be of service to many disciplines from archaeology , engineering, medicine • The tools changed in 1900 from manual graphics to mechanical instruments • in 1910, to multispectral sensors in the 1950´s, to computers and space technology • in the 1960´s. to digital tools for automation in the 1990´s for mapping • 8. The development of these tools resulted in a duplication of effort with the • computer vision community, which needed the tools for non topographic tasks
9. However, photogammerists of the new generation are in the process and • have been able to master computer vision tools • This scenario will continue, since the tasks to record, analyze,classify and measure • the environment in realtime still offer an immense challenge • 11. The changes between Beijing 2008 to Prague 2016 clearly demonstrate the • change of tools:
New Optical Sensors • - digital high resolution cameras • - digital medium resolution low cost cameras with oblique uses • - laser scanners supplemented by optical imaging • 13. New Range of Platforms • - high resolution satellites with high capacity for global coverage • - satellite constellations for high temporal coverage • - small low cost satellites • - UAV´s • - terrestrial applications from mobile vans • 14. New Non Optical Sensors and Hyperspectral Sensors • - radar (TerraSar X, Cosmo Skymed, Tandem X) • - Enmap • 15. Automation of the Processing Chain • - Utramap • - Pixel Factory
3D databases • Automatic or Semiautomatic feature extraction • Improvement in the Speed and Quality of Mapping • - Google Earth, Google Maps, Google Street View, Google Ground Truth • - Bingmaps • - Yandex • 19. Intergovernmental efforts • - UNGGIM (integration of geodata with statistics) • - GEO (environmental research by ESA Copernicus Sentinels)
