The MODIS land data storage methodology: level 2 grid

The methodology used to store a number of the Moderate Resolution Imaging Spectroradiometer (MODIS) land products is described. The approach has several advantages over conventional approaches used to store remotely sensed data sets and may be applied to any remote sensing data set where the observations are geolocated to sub-pixel accuracy. The methodology will enable new algorithms to be more accurately developed because important information about the intersection between the sensor observations and the output grid cells are preserved. The methodology will satisfy the needs of the MODIS land product generation algorithms; will allow sophisticated users to develop their own application specific MODIS land data sets; and will enable efficient processing and reprocessing of MODIS land products.
