Astron., vol. 7, paper 94-0597.Y. YAMAGUCHI, H. TSU and H. FUJISADA, (1993) Scientific basis of <strong>ASTER</strong> instrumentdesign. In Proc. SPIE, vol. 1939, pp. 150-160.13.10 HDF-EOS Data FormatWhat data format is the <strong>ASTER</strong> Level-1 dataset in, and what software can I use to accessit?<strong>ASTER</strong> data is provided in HDF-EOS format. HDF stands for Hierarchical Data Format, whichwas developed by the National Center for Supercomputing Applications (NCSA) at theUniversity of Illinois at Urbana-Champaign. HDF was originally developed for handlingmassive arrays to support supercomputing applications. HDF-EOS is a specific implementationof HDF to handle swaths, grids, and points.Are there any tools available for converting <strong>ASTER</strong> data into other formats, e.g. GeoTIFFso I can use them in other packages e.g. IDL/ENVI, Arc/Info, ERDAS/Imagine?Among the commercial image processing software packages, ENVI version 3.5 (from RSI)allows you to ingest <strong>ASTER</strong> data. Other packages that handle <strong>ASTER</strong> data include Imagineversion 8.5 (from ERDAS), PCI version 8.2 (from PCI Geomatics), Matlab (from MathWorks),Noesys (from RSI), and Idrisi (from Clark University). The <strong>ASTER</strong> team at JPL has developedfree tools for processing <strong>ASTER</strong> data. They are available from: http://winvicar.jpl.nasa.gov/Refer Appendix IV for more on available public domain software.Where can I get help on understanding more about HDF & HDF-EOS formats?HDF, developed by NCSA, is a public domain software that is acknowledged for its portability.HDF software includes I/O libraries and tools for analyses, visualization, and data conversion.<strong>NASA</strong> decided to incorporate a specific implementation of HDF for its EOS mission-deriveddata sets called HDF-EOS. This includes specific data models for storage and handling of swath,grid, and point primitives. There are a number of on-line sources of information on HDF, andHDF-EOS:http://hdf.ncsa.uiuc.eduhttp://hdf.ncsa.uiuc.edu/hdfeos.htmlhttp://hdfeos.gsfc.nasa.gov/cfdocs/hdfeos/workshop.cfmhttp://hdfeos.gsfc.nasa.gov/cfdocs/hdfeos/RESOURCE.htmlAppendix IV provides more information on public domain software that handle HDF-EOS andthe links to access and procure them.86
