EuroSDR/ISPRS Oblique Workshop 2017, Barcelona - Report

Tom attended the EuroSDR/ISPRS Oblique Workshop in Barcelona this year. Here's his report.

With the rapidly increasing quality of airborne imaging systems and innovations in dense image matching techniques, there is a very positive growth in the use of oblique camera systems. Particularly so for National Mapping agencies but also for commercial companies who are embracing the advances in technology that allow them to produce high quality geospatial data through highly automated and cost effective workflows. 

The 2017 EuroSDR/ISPRS Workshop on Oblique Aerial Cameras was held in Barcelona and hosted at the Institut Cartogràfic i Geològic de Catalunya (ICGC). To ensure we make the most of the continued momentum into research and use of oblique systems it was critical we attended. The workshop is designed to bring together industry experts/researchers and users of oblique systems to discuss the latest developments and present their projects and results. 

At the event, GeoXphere presented the XCAM and its unique Circle method, allowing for a more cost effective way to capture data and produce true-orthophotos, oblique imagery and 3D data from a single flight.

There were also some fascinating presentations from National Mapping agencies, such as SDFE in Denmark – who captured 10cm Oblique Imagery for the whole of Denmark in a single year. The ability to easily display and interpret oblique imagery has been key to the success of a property valuation project in Denmark. Oblique frames are often discarded as a by-product of producing 3D meshes however projects such as this show the value in this data, which can be easier and faster to disseminate than 3D data.

In addition to this project, the SDFE recognised that there was real economic value in releasing data with an Open License, encouraging further commercial and educational use of the data. It’s really encouraging to see NMCA’s recognise the economical benefits of releasing data to the public and there’s no doubt this will help to proliferate the use of oblique and 3D data throughout the industry. 

We also heard from Ordnance Survey, presenting on the advantages of using oblique datasets in their work and how they see this fitting into future projects, particularly within Smart Cities / 'Digital Twin' mapping such as the 5G roll-out in the UK. Ordnance Survey also gave credit to the EuroSDR E-Learning courses, designed to help knowledge transfer from research to industry. 

It was interesting to see the work being done by researchers from many different countries and to hear the perspectives of the end users. There is certainly a lot more progress to come in this area, and we are excited to help push the boundaries of oblique capture.

Our key points to take away from this event were:

  • 3D data will be key to the management of smart city development.
  • There is still a lot of work to do, particularly with the dissemination of 3D data, i.e through web viewers.
  • Oblique Imagery is incredibly valuable and given the ease of distributing this data, we must provide XCAM users with an easy way to distribute and use oblique frames. 

We had a great time meeting new people and catching up with existing clients and we look forward to the next event!
