How to access the search interface

The search interface can be accessed from the top menu from "Get Data->Integrated search interface" or directly from the front page using the "Quick access to data" block on the left.

 

The search interface

The search interface is composed on a central map and several filters:

The map

When accessing the search interface the map is showing the latest available datasets on the satellittdata.no portal. Actions can be performed interacting with the map:

map search​

  • Select Projections: the projection of the map and the bounding boxes can be changed using this button.
  • Create bounding box filter: click this button to create a bounding box and define a geographical filter on the results.
  • Visualize all Sentinel products in Map:  the available products will be loaded and visualized directly on the map.
  • Reset search: click to clear the filter and start a new search
  • Reset map: resets the map

Map widgets

  • zoom: clicking the +/- buttons on the left of the map it is possible to zoom in and out.
  • E: zoom to extent.
  • menu search map: clicking the button a side panel will show to add or remove map layers and features as well as change the opacity of the overlayers.
  • gelocation button:  location names can be searched with an autocomplete function (i.e. start typing a location and select from the drop-down menu). All datasets within that region will show as result of this filtering (see below).
  • inset button: show inset of map
  • full screen button: show full screen mode

location search​

 

The filters

The results of the search will be dynamically updated when filters are selected.

  • Instrument: The instrument used.
  • Mode: The instrument modes.
  • Isotopic categories: The general subjects for which geospatial data may be relevant as defined by ISO.
  • Start date year/month/day: Alternative and/or additional temporal extent filtering
