Hyperspectral Data Delivery Contents

This page describes the file formats and delivery structure used in the hyperspectral data deliveries.

Delivery Structure

A standard delivery directory contains the following sub directories:

• dem - Contains a Digital Elevation Model suitable for use with APL
• doc - Contains a copy of the most recent data quality report
• flightlines - Contains the level-1 data
  • fodis - Contains radiometrically calibrated FODIS data. This is only present if Eagle data has been collected.
  • level1b - Contains radiometrically calibrated image data and mask files.
  • line_information - Contains XML files (1 per flight line) describing the data and flight line information
  • navigation - Contains post-processed synchronised navigation data
• logsheet - Contains a logsheet that gives a brief overview of the flown project
• project_information - Contains an XML file describing the project information
• screenshots - Contains JPEG files of level-3 processed data including mosaics.
• sensor_FOV_vectors - Contains field of view sensor vector files required for APL geocorrection

Digital Elevation Model

The format of the delivered Digital Elevation Model (DEM) is band Sequential (BSQ) ENVI format binary data. The projection is in WGS-84 latitude and longitude, with heights relative to the WGS-84 spheroid. There is an accompanying ASCII text header file containing the required information to read the binary data. In most cases, the DEM will have been created from ASTER data.

Fodis, Level1b and Navigation files

The files contained in the fodis, level1b and navigation directories are in band interleaved by line (BIL) ENVI format binary data. There is an accompanying ASCII text header file containing the required information to read the binary data.

Line and Project information

The files in the line_information and project_information directories are in XML format. They conform to the ISO19115 standard.
