About RangeView Data

MODIS data collected by the Terra and Aqua satellites, part of NASA's Earth Observing System (EOS) EOSDIS Program.

AVHRR data collected by National Oceanic and Atmospheric Administration satellites (NOAA-13 to NOAA-17).

MODIS data turned into a vegetation greenness product by MODIS system members all over the U.S.

AVHRR data turned into a vegetation greenness product by the EROS Data Center (EDC)

The EROS Data Center (EDC) is serving as the Distributed Active Archive Center (DAAC) responsible for processing, archiving, and distributing EOS land science data and products (including MODIS and AVHRR). Data are radiometrically and geometrically corrected, then distributed in binary format. Some data must be purchased through subscription, while others are distributed free of charge.

ARSC personnel have created scripts to automate most of these processing tasks:

MODIS:
1) acquire data via FTP download
2) stitch together 2 or more image tiles to create one large image that covers the western U.S.
3) Convert image to TIFF file and apply correct color map for RangeView tools
4) Load new image into RangeView tools

AVHRR:
1) acquire data via FTP download
2) Use ArcInfo to convert binary data to a TIFF image file, applying the correct color map
3) Load new image into RangeView tools and ARIA image archive
