**Draft**Ningaloo HyVista hyperspectral data - radiance and reflectance - April 2006

Brief description

HyVista Corporation was contracted by AIMS to acquire hyperspectral data over the Ningaloo Marina Park area NW-WA, Australia. A total of 67 HyMap image strips were acquired, within 11 individual Blocks, between the 20th of April 2006 and the 2nd of May 2006. The HyMap data products include radiance, reflectance and geocorrected data with pixel size of 3.5m.

Lineage

Statement: HyVista Corporation installed the HyMap sensor to a twin engine aircraft which flew from 21th April to 2nd May. The survey was carried out by pilot Stuart Criddle â AAS, operator Mike Hornibrook â HyVista and QC and project manager Peter Hausknecht â HyVista. The flight planning was done by Peter Cocks â HyVista.

The data acquisition (DA) was conducted in individual blocks â each HyMap data block was acquired in one sortie â and whenever possible HyVista tried to fly more then one block in one day. Due to survey time restrictions Block F was acquired on two different days to allow for optimal sun angles. The thumbnail shows the Ningaloo marine park outline together with color coded bathymetry lines and the flight pattern planned for the Ningaloo HyMap survey. The textbox to the right shows the number of lines contained in each block, the optimal survey time based on the survey direction, number of minutes for DA in normal conditions and the line direction towards North.

The HyMap survey was planned to cover the water areas to the 20m bathymetry line (light purple) â two blocks (G & F) cover it all the way to the 50m line (dark purple). The survey was also extended to cover the Muiron Islands and the land area past Exmouth town. The area covered total 3400 square kilometers collected at 3.5m pixel size.
