How does the viewer work

EMODnet Chemistry provides an interoperable on-line viewing service (Ocean Browser) for the visualization of the products developed with the harvested chemical data and for products available from the other thematic portals

OceanBrowser

OceanBrowser is a web-service that allows users to visualize gridded fields on-line. It is based on open standards from the Open Geospatial Consortium (OGC), in particular Web Map Service (WMS) and Web Feature Service (WFS). These standards define a protocol for describing, requesting and querying two-dimensional maps at a given depth and time. OceanBrowser currently supports the following operations:

  • Visualization at a selected depth and time of the horizontal sections of the 4-dimensional fields (longitude, latitude, depth and time).
  • Interpolation and visualisation of the climatological fields on arbitrary vertical sections defined by users.
  • Animation of the horizontal and vertical sections in order to study the evolution in time.
  • Image export in several formats: raster (PNG) or vector (SVG, EPS, PDF). It can also be saved as a KML file (so that the current layer can be visualized in programs like Google Earth).
  • Download of the underlying 4-dimensional netCDF file, either as a whole from the interface or only as a subset using the linked OPeNDAP server.
  • Import of third-party layers by using standard WMS requests. The user needs only to specify the URL of the WMS server and its supported version.

More operations can be performed, information about this options can be found at the Ocean Browser wiki.
