(Author's Note 5/18/2020: GDEx has since been retired. Users are encouraged to use NASA Earthdata Search in place of Reverb. Several of these datasets are also available in AppEEARS.

The Land Processes Distributed Active Archive Center (LP DAAC) released a new version of the Global Data Explorer on 3Sep2014. Improvements to GDEx include a link to the LP DAAC System Status page, a User Guide, and the MODIS Land Cover (MCD12Q1.051) data product's International Geosphere Biosphere Programme(IGBP) layer.
GDEx was designed to provide seamless selection of tiled raster data products via geographic navigation and selection tools. Additionally, users may choose from available processing options including format, and projection (depending on the data product selected).
