The Gap Analysis allows us to get a broad idea of which parts of the region have been covered to some extent. The initial view offered shows the coverage level on a 1 degree block. If the user clicks on one of these 1 degree blocks, the page will refresh to show that area in pentad scale.
The user can then click on the pentad of interest to access the submissions summary for the selected pentad, as well as an annual summary of the Quarter Degree Grid Cell in which the pentad falls (below the map). If the user selects an empty pentad, the summary of the Quarter Degree Grid Cell is loaded below the map.
Quarter Degree grid cell (QDGC):
A 15 minute x 15 minute coordinate grid super-imposed over the continent to for spatial reference. One QDGC comprises of 9 pentads.
