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
1. Since the foundation of ISPRS in 1910 , 22 International Congresses in Photogrammetry and Remote Sensing took place ; now they arescheduled every 4 years
2. These Congresses document the progress of the discipline
3. Progress is measured by 3 indicators:- tasks- traditions- tools
4. 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
5. Mapping became of such relevance around 1900, that a mapping
profession was created 1910, the tradition of photogrammetry; but ISP(RS) already had1910 had a section of „non-topgraphic photogrammetry“.
6. While photogrammetry still is considered as a geodetic discipline, it continues to be of service to many disciplines from archaeology , engineering, medicine
7. 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
10. This scenario will continue, since the tasks to record, analyze,classify and measurethe environment in realtime still offer an immense challenge
11. The changes between Beijing 2008 to Prague 2016 clearly demonstrate thechange of tools:
12. 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
16. 3D databases
17. Automatic or Semiautomatic feature extraction
18. 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)
