2nd EuroSDR Workshop on High Density Image Matching for DSM Computation

EuroSDR Commission 2

Federal Office of Metrology and Surveying (BEV)
Meeting room A802
Schiffamtsgasse 1-3
1020 Vienna

June 13, 2013, 11:00 - 17:30, Social Event in the evening
June 14, 2013, 8:30 - 15:00

The workshop goal is to identify the status and trends in high resolution image matching of aerial imagery and to give recommendations to developers from the users (NMCA) point of view as well as to EuroSDR for project steering. The 1st workshop, held in Vienna in February 2012, demonstrated the potential but also identify the lack of experience. As an outcome, a benchmark typical for NMCA production processes was set up.

Benchmarking of different approaches for the generation of high resolution digital surface models is necessary for NMCAs and developers alike, showing the strengths and weakness of different approaches and the possibility for integration into a processing workflow.

The workshop addresses practicioners, scientists, and photogrammetric software companies. This 2nd workshop approaches specifically participants of the benchmark. These are especially

  • National and regional mapping agencies, engaged in capturing, generation, and processing of digital topographic data, more specifically digital surface and terrain models.
  • Researchers working on high density matching algorithms with an interest in benchmarking the performance of their algorithms in the application domain of NMCAs.
  • Developers and product managers of photogrammetric software for DSM generation from aerial imagery.

Participants will gain a deeper understanding of the performance of dense matching algorithms. This will enable them to select suitable approaches for deriving digital topographic data meeting the individual requirements.
