Focus on HYCOS project

Hycos 1

  • News

Project summary

Developing an innovative method of monitoring the coastal erosion using the hybridation of three data sources: LiDAR, photogrammetry, satellite. The project will last 10 months.

 

Partners

GEOSAT is a group of 140 people involved in all domains related to 3D/ 4D measurement: underground network detections, 3D scanning and modelling, Mobile Mapping, Land Surveying. (www.geo-sat.com)

 

GeoNumerics provides consultancy services, markets software components and conducts research-and-development (R&D) projects in the field of high precision navigation and kinematic surveying, especially focusing on sensor orientation and calibration, and trajectory determination.

Kick-off meeting held in Bordeaux on January 25th with the GeoNumerics, GEOSAT and Telespazio (third partner). Minutes of the meeting:

  • Structure of the project
  • Ground System by GEOSAT
  • MapKITE : Tandem air-and-ground 3D Mapping
  • Needs and challenges of MapKITE in Hycos
  • Satellite Imagery by Telespazio
  • Outcome of Hycos
  • Links with local authorities and continuation in 2019
  • Test plan (March 2018)

First campaign – Cap Ferret (France) March 21st and 22nd

 

TEST1 took place in the south-most part of Cap Ferret (see next slides for details). The selection of this place is the result of considering:

  •  Relevance of the area in terms of impact of coastal erosion to society
  •  Suitability in terms of scientific requirements
  •  Ease of access

The selection of this week is the results of crossing:

  •  Project schedule & Consortium preferences
  •  Satellite imagery favourable conditions
  •  Low tide happens around mid day.
  •  Tuesday, 20th: actual Sentinel2A imagery + (Monday pre-test, Tuesday actual flights)

Goal: capture the breakline of the dune (definition of “coast”)

  •  Height difference beach-top of dune = 10m – 16m
  •  MMS will capture the beach and “façade” of the dune; drone will complement with top of dune and satellite
