2015 Big Windy, Oregon 4-Band 8 Bit Imagery

Item Identification

Title:	2015 Big Windy, Oregon 4-Band 8 Bit Imagery
Short Name:	2015_bigwindy
Status:	Completed
Publication Date:	2017-04-20
Abstract:	These data are LiDAR orthorectified aerial photographs (8-bit GeoTIFF format) within the Oregon Lidar Consortium Big Windy project area. The imagery coverage is extended a minimum of beyond the project AOI. A GSD (Ground Sample Distance) resolution of 3 inch was used for each four-band color pixel. QSI recommends viewing the orthoimagery in ESRI ArcMap software using a raster catalog. For best results, stretch type should be set to 'None' and Gamma Stretch should not be applied (Layer Properties -> Symbology Tab). The circuit is projected in OGIC. Units are in International feet.

Purpose:	This dataset provides high resolution orthoimagery for the Oregon Lidar Consortium Big Windy study area.

Data Quality

Accuracy:	These data are not attributed. \| Quantitative Value: None \| Quantitative Test Explanation: These data are not attributed.
Horizontal Positional Accuracy:	To assess the spatial accuracy of the orthophotographs, they were compared against check points identified from the LiDAR intensity images. The checkpoints were distributed evenly across the total acquired area, and were measured on surface features such as painted road lines and fixed high-contrast objects on the ground surface. Horizontal accuracy applies only to the portion of the swath that was orthorectified to the LiDAR-derived DEM. Outside of that, accuracy and radiometry at ortho seams are not guaranteed. The accuracy of the final mosaic was calculated in relation to the LiDAR-derived control points. The orthophoto horizontal accuracy is reported as the root-mean-square error (RMSE). For this data set, the RMSE is 0.712 feet.
Completeness Report:	This data set covers the spatial extent of true color imagery data obtained during this survey.
Conceptual Consistency:	The data represented were acquired under a contract with Oregon Lidar Consortium. Information regarding the use of this dataset should be directed to the owner.

Process Steps

Process Step 1

CC ID: 1310004

Description:	Flight lines have been examined to ensure that there was at least 60% sidelap, there are no gaps between flight lines, and overlapping flight lines have consistent elevation values. All orthophotographs have been processed and reviewed for contracted accuracy and completeness. Orthophoto mosaics were reviewed at a scale of 1:2000 and reviewed against the LiDAR intensities to ensure no seam artifacts or offsets. Raw acquired images were radiometrically and geometrically corrected using the camera's calibration files. The resulting radiometry is then manually edited by digitally adjusting output levels, exposure and intensity, atmospheric haze correction, and applying hotspot dodging. This ensures that each image has the appropriate tone, no pixels are clipped, and that each image frame is blended with its neighbors. Once radiometry has been edited, separate RGBI and Panchromatic images are blended together to form single pan-sharpened 4 band TIFF images. During the mosaicking stage, orthorectified frames are color balanced a second time using an automated global tilting method and in certain cases, further manual balancing. Despite these extensive radiometric blending techniques, occasional frame to frame radiometric discrepancy may exist within the final mosaics due to bi-directional solar reflectance, changing sun angle, or difficult atmospheric conditions.
