Description:
Abstract:
These data are LiDAR orthorectified aerial photographs (8-bit GeoTIFF format) within the Oregon Lidar Consortium Turnbull 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 Turnbull study area.

Horizontal_Positional_Accuracy_Report:
To assess the horizontal accuracy of the orthophotographs, artificial check points were established. Twenty check points, distributed across the total acquired area, were generated on surface features such as painted road lines and fixed high-contrast objects on the ground surface. They were then compared against check points identified from LiDAR intensity images. The root mean square error (RMSE) for the Turnbull study area final mosaic is 0.166 meters and was calculated in relation to the LiDAR-derived check points.

Process_Step:
Process_Description:
Orthophoto Data Processing: 1. Acquired frames were reviewed to ensure complete coverage of the study area and absence of any obscuring features within the frames such as clouds or fog. 2. Image frame radiometry was edited to create the most homogeneous tone/coloration possible across the entire study area, and image frames were exported as 8 bit tiffs. 3. Photo exterior orientations (EO) were computed using POS processing software, based on independent data from the LiDAR system, IMU, and aircraft. 4. Computed exterior orientations were applied to the radiometrically corrected tiffs, and aerial triangulation was performed to align photos to each other as well as to ground control RTK points. 5. Adjusted image frames were draped upon a DEM generated from the LiDAR grounds and orthorectified, generating 8 bit GeoTiffs for each acquired frame. 6. Individually orthorectified GeoTiffs were mosaicked together to form a single seamless image and to correct for any remaining radiometric inconsistencies, and then output as GeoTiffs according to the specified tiling scheme in order to yield manageable file sizes. 7. The output mosaic GeoTiff tiles were compared to the LiDAR intensities in order to assess their accuracy.
