| description:

The DMC images were aerotriangulated to support digital ortho image production for the Winnebago County, WI project area. Airborne GPS and ground check point data was provided by AERO-METRIC, Inc. The original project was referenced to the North American Datum of 1983 (NAD83), Wisconsin State Plane Coordinate System horizontally and to the North American Vertical Datum of 1929 (NAVD29) vertically. Units were in US survey feet. The DMC images, ABGPS data, and ground check point data were used as inputs to the Zeiss/Intergraph ImageStation Automatic Triangulation (ISAT) softcopy program. ISAT correlated image points and aerotriangulated the block of images to create exposure station exterior orientations. All ground checkpoints were manually measured on the imagery. These ground checkpoints were included in the aerotriangulation adjustments as unconstrained points for absolute ground location verification. The scale of the aerial photos was 1:25392 and 1:12700. The photography was captured on April 11, 2009. Rectification was done using the aerotriangulation data, raw DMC images, and the processed LiDAR data. These rectified images were used to draw seamlines. The images were then dodged. The dodged rectified images were mosaicked, balanced, and cut into final image sheets. The final sheets were viewed and artifacts were removed as well as other edits performed. A MrSID compressed mosaic of the .5 foot Menasha and Oshkosh areas and the 1 foot Winnebago County rural area was then processed at a compression ratio of 55:1. The MrSID image was saved to a file called p2009.sid in the WINGS Project.</ |
