WorldView 2 Imagery - Oahu

USDA has purchased a Enterprise Premium license for this Orthoimagery dataset from DigitalGlobe, Inc. Any government, education, not-for-profit agency and public/individuals not engaged in using the "Product for Commercial Exploitation or Commercial Purposes" can use this licensed data. Use of this product for Commercial Purposes by a person/company/organization for a profit or fee is strictly prohibited. Please refer to the separately attached license from DigitalGlobe, Inc. for additional information. Digital orthoimagery combines the image characteristics of a digital image with the geometric qualities of a map. The primary dynamic digital orthophoto is a 50 centimeter ground resolution, image cast to the customer specified projection and datum defined in the Spatial Reference Information section of this metadata document. The overedge is included to facilitate tonal matching for mosaicking and ensure full coverage if the imagery is reprojected. The normal orientation of data is by lines (rows) and samples (columns). Each line contains a series of pixels ordered from west to east with the order of the lines from north to south. DigitalGlobe WorldView-2 Satellite Orthoimagery was delivered to USDA in GeoTIFF file format. USDA-NRCS-NGMC processed the DigitalGlobe delivered WorldView-2 (WV-2) Multi-Spectral/Pan data bundle to produce an 8 Band, 16 Bit Pan-Sharpen Mosaic using ERDAS 2011 in three sections. The individual sections were rescaled to 8-bit and the statistics were recalculated before merging into a seamless 8-bit full island mosaic. Bands 2, 3 & 4 were subset from the 8 band, 16-bit mosaic to create a natural color (RGB) mosaic.The resulting mosaic was rescaled from 16-bit to 8-bit depth using ERDAS 2011. The image contrast level was adjusted using the Breakpoint editor and breakpoints were saved and applied to the LUT stretched output file. LizardTech GeoExpress 8 was used to create a compressed Generation 3 MrSID from the RGB mosaic. The MrSID compressed file is delivered with a separate FGDC compliant metadata file. The composite file contains the following three Multi-Spectral bands: Band 2: Blue (450 - 510 nm) Band 3: Green (510 - 580 nm) Band 4: Yellow (585 - 625 nm) For additional information, please contact Hawaii Statewide GIS Program, Office of Planning, State of Hawaii; PO Box 2359, Honolulu, Hi. 96804; [phone]; email: [e-mail]; Website: https://planning.hawaii.gov/gis.
