Grids and Mapping

Equal Angle Grid

All of the Filled NDVI Products are stored on an equal angle lat-lon grid. The grid resolution is dependant on the product ranges from 1-minute resolution (2 km at the equator and < 1 km at the pole) to 10°.

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.
