Description:

Abstract:

This portion of the data release contains a digital image mosaic with 1.0 foot-per-pixel resolution of the Pala'au area on the south coast of Moloka'i. This image mosaic was generated using digitized 1:10K natural color photographs collected in January 2000 by Air Survey Hawai'i, Inc. for the U.S. Geological Survey. Also available is a lower-resolution 'browse' graphic of the image mosaic area and associated metadata.

Purpose:

The lack of geographic and thematic maps of coral reefs limits our understanding of reefs and our ability to assess change. The U.S. Geological Survey (USGS) has the capability to compile digital image mosaics that are useful for creating detailed map products. Image maps covering the shallow near-shore coastal waters have been produced for several of the main Hawaiian Islands, including Hawai'i, Maui, Moloka'i, and O'ahu and are presented in JPEG2000 (.jp2) format.

Source_Contribution:

Lidar bathymetry data were used to help geometrically control the aerial photography

Process_Step:

Process_Description:

Digital-image mosaics were generated by first scanning 1:35K aerial photographs at 1.0 meter-per-pixel resolution. The individually scanned digital images were tone- and color-matched and then combined together using spatial matching. Separately, black and white digital orthophotoquads (DOQs) of the same areas were then combined with shaded-relief images generated from lidar bathymetry data. The resulting black and white shaded-relief images covering both near-shore coastal waters and on-land areas became the geometric 'masters' for the mosaics generated from the aerial photographs. The aerial-photograph mosaics were geometrically corrected to overlay the master data set by using hundreds of image-to-image geometric control points and 'slaving' the mosaic onto the DOQ-lidar master.
