excepting HyMap data acquisition and items below indicated by
(HyVista), which will be performed by HyVista Corporation.
AIG agrees to supply the following for each Scene either on CDs or
tape:
Image data in units of radiance (W/cm-2/nm/sr); BIL format data files with
corresponding ENVI header files (HyVista)
GPS positions of the plane during data acquisition (HyVista)
Dark current measurements (HyVista)
Spectral calibration parameters: band centers and band shape (HyVista)
Image data corrected to apparent reflectance using an atmospheric model;
BIL format data files with corresponding ENVI header files
A single-band image of precision geocorrected data
Geocorrection information sufficient to precision geocode other bands/results
OBLIGATIONS OF SPONSOR
Sponsors shall supply the start and finish coordinates of each Individual Site
in latitude/longitude pairs (decimal degrees using the WGS84 datum).
Larger areas can be covered at an incremental cost. If such areas are to
be covered, in order to provide uninterrupted coverage of adjacent data
strips, a 20% overlap for each strip with its neighbor should be allowed.
AIG and HyVista Corporation accept no responsibility for sponsors
supplying incorrect coordinates for survey sites; sponsors will be charged
in full for the full data acquisition fee in these instances.
DATA ACQUISITION
Data will be acquired at a date nominated by AIG and HyVista with input
from the Sponsor. Data will be acquired in weather conditions to the
satisfaction of AIG and HyVista. Sponsor will be notified of proposed
acquisition of data from an elected study site not less than 24 hours prior
to acquisition. AIG and HyVista reserve the right to omit data
acquisition for a Sponsor's chosen site if adverse weather conditions
preclude the acquisition of data to corporate quality standards.
DATA QUALITY
All data presented to Sponsor shall bear full 126-channel coverage. To keep
turbulence effects to a minimum the scanner is mounted on a stabilized
platform the Jena SM 2000. The geometric integrity of the data therefore
will be within the platform performance characteristics as supplied by the
manufacturers and the operators will endeavor to keep turbulence effects
to a minimum or abort the line if the motion is too great. Cloud cover
will be less than 10 percent total for a named study area. Spatial
accuracy of the data is limited by the on-board GPS of the aircraft.
Should a sponsor be dissatisfied with the data quality, the following
procedure will be followed: The data in question will be supplied for a
quality control assessment to 2 impartial experts, one selected by each
