The entire project area encompassed an area of approximately 197 square miles with the Mandan area encompassing approximately 80 square miles. A Leica ADS40 Digital Camera system including an inertial measuring unit (IMU) and a dual frequency airborne GPS receiver was used for the digital image acquisition. Imagery acquisition was performed on April 17th and April 22nd of 2005 at 4800' AMT. Ground control survey was conducted by Kadrmas, Lee and Jackson of Bismarck, North Dakota. A survey report summarizing methodology and results was submitted in hardcopy and a digital file in PDF format. GPS data was collected on two new monuments and 11 existing MPO monuments. The resulting coordinates for each new station are referenced to NAD 83(96) datum in North Dakota State Coordinate System, South Zone (3302). The horizontal units were international feet. The GPS Orthometric Heights were determined by calculating the Ellipsoid-Geoid separation using Geoid 99 model and are based on NGVD 1929 international feet. The existing DTM data which Horizons had collected in 2001 was updated to support 2' contours where requested. New mapping was performed on 40 sections and an additional 30 sections of DTM collection was done for ortho rectification only. Color digital orthophotos in TIFF format with .TWF files were produced with a resolution of 6" utilizing the ADS40 imagery and the updated DTM. Purpose: The orthophotos will be used for scientific research, planning, and production of GIS products.

The GPS data was processed with forward and reverse processing algorithms. The results from each process, using the data collected at the airport, were combined to yield a single fixed integer phase differential solution of the aircraft trajectory. The differences between the forward to reverse solution within the project area were within project specifications (<10cm) in both the horizontal and vertical components, indicating a valid and accurate solution. An IMU was used to record precise changes in position and orientation of the ADS40 Digital Camera System. All IMU data was processed post flight with a filter to integrate inertial measurements and precise phase differential GPS positions. The resulting solution contains geodetic position, omega, phi, kappa, and time for digital image processing.

The raw image was download in the field with GPro to a portable workstation. This enabled a quick look at image quality and coverage. Using the Applanix POSgps software package the GPS data was differentially processed against a base station. After the differential GPS solution was checked and verified the Applanix POSproc program was used to compute an integrated GPS/IMU navigation solution at one-second intervals. Using the GPS/IMU trajectory computed by the Applanix POSproc software and the camera calibration, GPro computed a full x,y,z, omega,phi,kappa exterior orientation of each scan line. Using the orientation data file produced the L0 imagery was resampled. The resampling removes most aircraft motion and provides epipolar geometry imagery for stereo viewing, automated aerotriangulation and automated DEM extraction. The Level 1 epipolar-resampled and georeferenced imagery usually will provide a pixel?s true ground location to within a few pixels without any additional processing. To improve accuracy, a fully automatic aerotriangulation process was performed to minimize the residual errors in the GPS/IMU derived exterior orientations. The aerotriangulation also allowed the introduction of ground control and checkpoints to ensure the accuracy specifications were achieved. Automated aerotriangulation of ADS40 imagery was performed with the Socet Set Automatic Point Measurement (APM) tool. A digital elevation model (DEM) was required for orthophoto production. Using L1 imagery new DTM data was collected as well as existing DTM data was updated using KLT softcopy plotters with superimposition. The resulting updated and new DTM data was used for the generation of new 2' contours as well as DTM data to support the ortho only areas. Contours were generated utilizing ARC-VIEW 3.2. Graphic Edit and GIS technicians reviewed the contours generated and edited the DTM data where necessary to produce accurate 2' contours. The final reviewed map files were delivery in ARC Shape files with delivery on CD-ROM.
