L ROBERT KIMBALL AND ASSOCIATES Inc. 2008/04/24 Raster Image Digital orthophotos combine the geometric qualities of a map with the image qualities of a photograph. The orthos in this series have a ground resolution of 0.25x0.25 feet from color aerial photography taken at an approx scale of 1:7200 during the Spring of 2007. Each orthophoto image tile has 10000 x 10000 pixels and a geographic extent of 2500 x 2500 feet, with zero overlap between images. The images have been rectified to the West Virginia State Plane Coordinate System 1983 North American Datum (NAD83/2001 adjustment). The file consists of image pixels oriented 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. Orthophotos are numbered in accordance with the Basic Modular Unit naming scheme in which the orthophoto number refers to selected paired digits of the East and North coordinates of the southwest corner of the module. Digital orthophotos serve a wide variety of uses. The primary use of these orthophotos will be as a backdrop layer of visual information for various mapping efforts. These Orthophoto images are available in two formats. The raw uncompressed .tif/.tfw format datasets are available on External Hard Drive. Images compressed using Lizardtech's MrSid Publisher Software are available in .sid/sdw format. 2007 ground condition Complete As needed -78.2300 -77.8200 39.6200 39.2600 None Orthophoto Aerial Photograph Digital Orthophoto None Berkeley County none none Berkeley County Planning Commission Matthew T.

The digital imagery was generated with an 8-bit pixel depth for each of the three color bands (24 bit color pixel depth). The aerial film was kept free of dust marks, scratches, fog streaks, stains and blemishes to the maximum extent possible. A Leica DSW600 scanner was the device used for the scanning. This scanner is a high-resolution precision instrument with an aperture capable of producing scan resolutions of 8.5 microns, and a geometric accuracy of less than five microns. KLT Atlas software was used for the pixel-by-pixel rectification of the orthophoto imagery. The resampling method used was cubic convolution. This method produces superior results in areas with abrupt elevation changes. Orthophoto Images were reviewed by the contractor and the County for consistency in tone and contrast. All orthophoto imagery was visually inspected for completeness to ensure no gaps or image misplacement exist in the image area. Orthophotos were created using a mosaicking process to provide a seamless image coverage. The orthophoto horizontal positional accuracy and assurance of that accuracy depend in part on the accuracy of the data inputs to the rectification process. These inputs consist of the digital elevation model (DEM/DTM), aerotriangulation control and methods, the photo source camera calibration and scanner calibration. The accuracy of the data input was sufficient to produce orthophotos that meet National Map Accuracy Standards for 1"=100' orthophotography. The National Map Accuracy Standards stipulate that 90% of all well defined features not be displaced in excess of 1/30 inch for scales larger than 1:20,000 Optimal Geomatics April 10-14,And May 5-6,2007 ASCII Optimal Geomatics Unknown April 10-14,And May 5-6,2007 Date of Collection DEM Elevation data in the form of a LiDAR mission re-gridded for orthophoto rectification L.

This Aerial imagery was the source data used to enhance the LiDAR DEM data used for the orthorectifcation process, and was the imagery used to produce the orthophoto imagery. The rectification process requires input from a user parameter file to control the rectification process, camera calibration and aerial triangulation information, a digital elevation model (DEM/DTM) with the same area of coverage as the digital orthophoto, and an unrectified raster image file acquired from scanning the aerial film. These inputs were used collectively to register the raw image file mathematically to determine the location of the camera position and orientation with respect to the ground and to remove the relief displacement from the image file. The camera calibration report provides the focal length of the camera and the distances in millimeters from the camera optical center reference for spatial measurements made from the photograph. The camera used for the source photography was a Wild RC30 and Zeiss Jena LMK equipped with forward motion compensation. The calibrated focal length for the Wild RC30 camera at the time of photography was 152.193mm. Camera serial number: 5231. Lens serial no. 13246. And the calibrated focal length for the Zeiss Jena LMK camera at the time of photography was 152.179mm. Camera serial number: 272299c. Lens serial no. 7390598D. Photography was flown on 03/25/07 and 03/29/07 Ground control points were acquired from recovered monuments and GPS ground surveys and are Second Order Class 2 or better. This accuracy meets National Map Accuracy Standard (NMAS) for 1"=100' scale mapping. Ground control points are on the North Carolina State Plane Coordinate System 1983 North American Datum (NAD83/2001 adjustment). Analytical triangulation was performed to extend the horizontal and vertical ground control. A combination of photo center coordinates obtained through airborne GPS and ground control points were used for control of the analytical triangulation. Aerotriangulation was performed by softcopy methods using KLT Atlas software. Scans produced from the original film were used. A minimum of three passpoints were marked along the center of the stereo overlap area. One point near the center or nadir point of the photo and one point near each corner of the stereo model. These corner passpoints also served as tie points between strips. Point measurements were performed by softcopy methods using KLT Atlas software. A fully analytical simultaneous bundle adjustment was performed by a weighted least squares adjustment method using KLT Atlas aerotriangulation software. The root-mean-square error of passpoints computed in the analytical triangulation does not exceed one-fiftieth (1/50) of the denominator of the final map scale. The vertical accuracy does not exceed 1/10,000 of the flight altitude. The raster image file was created by scanning the aerial film with a Leica DSW600 scanner with an aperture of approximately 10 microns. This equates to a ground resolution of 0.25 foot from the 1:7200 scale photography. The DEM/DTM data was obtained by enhancing LiDAR data using softcopy photogrammetry methods. The seventy percent overlap raster images were viewed in 3D on KLT Atlas softcopy stereo systems. Breaklines were compiled as needed for orthophoto rectification where the change in terrain was in a linear form, such as along a stream bed, a road edge, a retaining wall or a ridgeline. DEM points were added manually where needed. Each stereo model was reviewed for completeness and accuracy by a second stereo operator before being used in the orthophoto rectification process. The vertical accuracy of the DEM/DTM is only sufficient to support the rectification of the aerial images and is not intended for contour generation. All of the above mentioned inputs were used by experienced photogrammetry technicians in order to complete the orthorectification process. Orthophotos were rectified using KLT Atlas software which is capable of pixel-by-pixel rectification. Cubic convolution was the resampling method used. Final tone and contrast adjustments were completed using a combination of KLT Atlas, PhotoShop software. 2007-2008 L. Robert Kimball and Associates Inc.
