Grids and Mapping

Equal Angle Grid

The Ecosystem Product is stored on an equal angle lat-lon grid at 1-minute resolution.

The upper left corner position of the first grid cell (1,1) is located at latitude 90°N and longitude 180°W. The convention used here is degrees north latitude are stored as positive numbers; while degrees west longitudes are stored as negative numbers. This allows lat/lon pairs to increase from top to bottom and left to right on the grid.
