How do I use the IceBridge Data Portal?

The IceBridge Data Portal allows for map-based visualization of flight paths over Greenland, Antarctica and Alaska. These flight paths show the courses of aircraft carrying IceBrdige instrumentation. Each flight line represents a single flight made on a specific day. Each flight carries multiple instruments for collecting data. Multiple data sets can be derived from each instrument. The NASA IceBridge project is comprised of these data sets.

The map display of the flight lines in the portal allows viewers to zoom in to the their areas of interest in order to see which flights passed nearby. Various map layers are available for display purposes. One can toggle the different views on the right-hand side of the map. The panels on the right-hand side allow viewers to filter the data to a specific range of dates, filter the data by specific instruments, view the details of a specific flight, and browse the available data sets in the data tree.

Selecting a flight on the map view will highlight the associated flight in the data tree in the bottom-right panel, and vice versa. In the data tree, viewers can drill down to see which instruments were operating on any given flight and which data sets were derived from said instruments.

The IceBridge Data Portal has a Northern Hemisphere and Southern Hemisphere map view. One can toggle between these two views via the tabs at the top of the map display. Also at the top of the map display are various map tools to pan and zoom, select flight lines, or measure distances.
