HDF/HDF-EOS data access, visualization and processing tools at the GES DAAC

To help users of remote sensing data, the NASA Goddard Earth Sciences Distributed Active Archive Center (GES DAAC) has developed a series of desktop and on-line tools. These are presented in this article. Various HDF readers for AIRS and MODIS data have been written in IDL, C and Fortran. HDFLook for AIRS and MODIS works as a desktop application as well as an integral part of various subsetting systems. AIRS QuickLook is an on-line package that allows users to view AIRS/HSB/AMSU Level-1B data online by specifying a channel prior to obtaining data. AIRS Online Channel/Variable subsetter provides on-line subsetting of the AIRS Level 1B and Level 2 data products. OASIS (Online data AnalySIS) is an IDL-based HTML/CGI interface for search, selection, and simple analysis of earth science data. TRMM Online Visualization and Analysis System is designed for quick exploration, analyses, and visualization of TRMM Level-3 and other precipitation products. WebGIS is online web software that implements the Open GIS Consortium (OGC) standards for requesting rendered maps from OGC-compliant servers.
