CDAWeb has now been expanded to include additional modes of display with overlaid maps and azimuthal re-projection of data to fixed geographic and magnetic coordinates. The focus of CDAWeb is the display of data as a function of time. Users may click on any thumbnail in a series to obtain an enlarged display of that given image. The enlarged images also include navigation buttons to move backward or forward among images in the sequence. Simple Images Imager data in CDAWeb is always available to examine as a simple, full-sized image of the pixels supplied with the data.
Simple images are typically the fastest to display.
As a first step to understanding auroral image data, original images can be displayed with overlaid geographic grid lines and continents. Auroral images can be displayed as azimuthal re-projection to a polar geographic view, with overlaid geographic grid lines and continental outlines. In an azimuthal projection, the circles of latitude are evenly spaced. Azimuthal Image Projection in Magnetic Coordinates Image display is also supported in projection to a frame of magnetic local time and invariant latitude. UVI Key Parameters are supplied at approximately 6-10 minute resolution depending on the instrument operating mode.
