Sample GVI Digital Data:

Samples of Global Vegetation Index (GVI) digital data are contained on this CD-ROM. These samples can be used to debug software that a user has written to read a particular type of GVI data. The following sample datasets include both Second and Third Generation GVI data. For detailed format information, refer to the section number indicated after the dataset type.

The filenames below are linked directly to the digital data. However, the user must provide the software (e.g. hex editor or image generator) and create an association with 'veg' file types to display or process the binary data. This disc does not contain executable software. Please refer to the instructions for your HTML browser on creating file type associations.
