The Land Processes Distributed Active Archive Center (LP DAAC) was established as part of NASA's Earth Observing System (EOS)
Data and Information System (EOSDIS) initiative to process, archive, and distribute land-related data collected by EOS
sensors, thereby promoting the inter-disciplinary study and understanding of the integrated Earth system. The LP DAAC is
responsible for archiving, product development, distribution, and user support of Moderate Resolution Imaging
Spectroradiometer (MODIS) land products derived from data acquired by the Terra and Aqua satellites and processing and
distribution of Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) data products. These data are applied
in scientific research, management of natural resources, emergency response to natural disaster, and Earth Science Education.
There are several web interfaces by which the inventory may be searched and the products ordered. The LP DAAC web site
(http://lpdaac.usgs.gov/) provides product-specific information and links to data access tools. The primary search and order
tool is the EOS Data Gateway (EDG) (http://edcimswww.cr.usgs.gov/pub/imswelcome/) that allows users to search data holdings,
retrieve descriptions of data sets, view browse images, and place orders. The EDG is the only tool to search the entire
inventory of ASTER and MODIS products available from the LP DAAC. The Data Pool
(http://lpdaac.usgs.gov/datapool/datapool.asp) is an online archive that provides immediate FTP access to selected LP DAAC
data products. The data can be downloaded by going directly to the FTP site, where you can navigate to the desired granule,
metadata file or browse image. It includes the ability to convert files from the standard HDF-EOS data format into GeoTIFF,
to change the data projections, or perform spatial subsetting by using the HDF-EOS to GeoTIFF Converter (HEG) for selected
data types. The Browse Tool also known as the USGS Global Visualization Viewer (http://lpdaac.usgs.gov/aster/glovis.asp)
provides a easy online method to search, browse, and order the LP DAAC ASTER and MODIS land data by viewing browse images to
define spatial and temporal queries.
The LP DAAC User Services Office is the interface for support for the ASTER and MODIS data products and services. The user
services representatives are available to answer questions, assist with ordering data, technical support and referrals, and
provide information on a variety of tools available to assist in data preparation. The LP DAAC User Services contact
