This metadata describes the 30cm pixel resolution, historical (1960s) orthophotography produced for the U.S. Department of Agriculture (USDA) - Natural Resources Conservation Service (NRCS) by Aero-Graphics. The ortho product provided is grayscale, 8-bit per pixel and delivered in USGS 1:12k quarter quad tiles (with a 100m buffer) in LZW compressed GeoTIFF format. This orthophotography is published in Universal Transverse Mercator Zone -5N, NAD83, meters, EPSG:269-5. Source aerial photography was collected between 1964 and 1965 at a scale of 1:24,000. Mixing photography from multiple dates was avoided as much as possible, therefore each tile is an orthomosaic composed of at least three overlapping aerial photos that were captured on one date (likely seconds apart). However, systematic differences in radiometry do exist between some adjacent orthophotos and between adjacent flight lines due to different conditions at the time of exposure (date of capture, flight direction, sun angle). No color or histogram matching was attempted and pixel values within these orthomosaics closely match the original pixel values captured during the scanning process.

Purpose: Rectified orthophotography for the State of Hawaii may serve as a basemap for GIS applications.
