About Aquaculture Atlas Generation (AAPS) About Aquaculture Atlas Generation (AAPS)

The Aquaculture Atlas Generation VLab is the implementantion of the Blue-Cloud Aquaculture Monitor demonstrator in the continuation of BlueBRIDGE AAPS, with planned improvement of Earth Observation based applications in European seas and in Indonesia thanks to the geospatial data resources that will be provided Blue-CLoud. It supports the generation and the review of aquaculture maps for offshore fish farms and coastal ponds. These maps are generated using satellite Earth Observation imagery. For the detection of aquaculture fish farms, high resolution optical satellite images are used together with new semi-supervised algorithms embedded into the CLS ¬©ACUITY software. For the detection of coastal ponds (and rice paddy fields), a dedicated algorithm has been developed and applied on Copernicus Sentinel-1 Synthetic Aperture Radar (SAR) and Sentinel-2 multispectral data acquired in 2014-2017. For the sake of comparison, a similar but simpler method can be applied on Landsat-5 acquired in 1994-1997. Three use cases are provided: Greece and Malta for fish farm detection, and Sulawesi, Indonesia for coastal ponds and rice fields.

 

The output maps are visualized in an integrated map-viewer. For Super User (i.e. thematic expert), this VRE enables the editing of attributes, the validation and publication of OGC-compliant data and catalog entries. The VLab relies on Blue-Cloud data services to manage users and content. It can be also useful to support Maritime Spatial Planners. 

 

This VLab allows to perform the following tasks:

  • Visualize generated geospatial data
  • Access to information at farm (feeding systems, farm material, farm design, fish species) but also cage levels (size, shape)
  • Edit attributes at farm level (for Super User only)
  • Overlay with Copernicus Sentinel-1 images
  • Compare the footprint of coastal ponds and rice paddy fields, and check their evolution over 20 years
  • Validate the attributes at farm level, and publish the results in a geonetwork catalog (for Super User only)

This VRE is currently equipped with the basic VRE facilities:

  • Workspace: for sharing objects of interest;
  • DataMiner: with a geographic proximity tool enabling to compute the closest NASO farms;
  • Social networking area: for supporting the discussions among members;
  • User management facility: for managing membership.
