Upon completion and quality assurance acceptance of the aerotriangulation solution, the adjusted control points and camera orientation parameters were used to set up the stereo models for photointerpretation within soft copy photogrammetric workstations.
Raw images were color balanced using I/RASC and a new look-up table was applied to images before saving to a new file. This balance process was completed to correct a green saturation that occured during the scanning process.
The orthophotography process was performed using an automated batch process. By using the raw imagery in combination with the aerotriangulation results described above, our softcopy system generated a digital ortho to a specified pixel size. Two copies of orthos were produced, pixel resolution was set at 1/2 foot and two feet.

A major objective of the Lake Worth Lagoon Management Plan is to restore, preserve and create seagrass beds, oyster bars and other submerged benthic habitat. Aerial surveys will enable Palm Beach County Department of Environmental Resources Management to determine the aerial extent of seagrass beds, mangrove habitat, oyster reefs, and spartina within the Lake Worth Lagoon and Intracoastal Waterway, while the fixed transect survey will reveal whether selected seagrass beds are stable, expanding or receding.

Existing ground controlpoints were used from previous mapping efforts. These points included both GPS survey points and control points collected from USGS 1m DOQQ's. Horizontal positional accuracy of the data meets NMAS for 1:24000 scale maps, approximately +/- 40 feet. The digital photography was reviewed over USGS DOQQ's. GPS points were also collected during field work at well defined features and compared against coordinates for the same features on the photography.
Upon receipt of the aerial photography, Avineon inspected it for tonal balance and contrast, completeness, signature appearance and scale prior to acceptance.
Are there legal restrictions on access or use of the data?
