The orthoimagery provided is 3-band (R, G, B), 8-bit per pixel and delivered in section tiles in uncompressed compressed SID/SDW (40:1) and uncompressed GeoTiffs upon requests. The data was collected between May 31st and June 10th over the Arkansas River during the record setting flooding the observed during the imagery collection period. This orthoimagery is published in Universal Transverse Mercator Zone 15N, NAD 83, meters\r\n Rectified orthoimagery for the State of Arkansas may serve as a basemap for GIS applications.\r\n \r\n \r\n \r\n \r\n 20190528\r\n 20190605\r\n \r\n \r\n State of Arkansas\r\n \r\n \r\n Complete\r\n None planned\r\n \r\n \r\n \r\n -94.625\r\n -89.625\r\n 36.5\r\n 33\r\n \r\n \r\n \r\n \r\n None\r\n Ortho\r\n Photography\r\n Orthophotography\r\n Imagery\r\n \r\n \r\n ISO 19115 Topic Categories\r\n imageryBaseMapsEarthCover\r\n \r\n \r\n None\r\n Arkansas\r\n Arkansas GIS Office\r\n \r\n \r\n This data may be used by the requested party for stated purposes and should not be re-distributed.\r\n This data is meant for use by requested parties.

The images match within four pixels of each other through out the project area.\r\n The ortho image tiles are checked for missing pixels, gaps, overlaps and other anomalies generally associated with digital orthophoto products. Any discrepencies in the ortho tiles are resolved through the use of proprietary and industry editing tools. Once the images are copied to the deliverable media they are further checked for naming, image completeness, and ability to be loaded in ArcMap.\r\n \r\n \r\n This orthoimagery meets ASPRS Class 1 Accuracy Standards\r\n \r\n 15cm RMSE\r\n Specification requirements were undefined for this projecy\r\n \r\n \r\n \r\n N/A\r\n \r\n 0.0\r\n Orthoimagery does not have inherent vertical accuracy.\r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n \r\n unpublished material\r\n Ground Control\r\n vector digital data\r\n \r\n \r\n None\r\n \r\n \r\n \r\n 20190909\r\n \r\n \r\n ground condition\r\n \r\n CONT\r\n Geodetic ground control is used to create a digital control file and control report as well as QC check of ortho accuracy.
