Description:
Abstract:
Martinez Corporation obtained color aerial photography covering Ramsey County and portions of Anoka, Dakota, Hennepin, and Washington counties. Great Lakes Aerial Survey (GLAS) was contracted to obtain the aerial photography on April 9, 2006. Martinez Corp. used elevation models provided by each of the counties mentioned above to create digital ortho images.
Purpose:
This data (digital orthophotos) can serve a variety of purposes, from general planning to field reference for spatial analysis to a tool for revision of vector information at ground level. It can also serve as a reference layer for GIS.
Supplemental_Information:
GLAS acquired aerial photography utilizing a gyro stabilized aerial camera equipped with forward motion compensation (Wild RC30, Wild Universal Aviogon /4-8, SN: 13373, CFL: 153.465 mm). This project was flown at an altitude of 5000 feet above ground level (AGL).

Process_Description:
Aerial Photography was scanned at a resolution of 14 microns (1814 DPI) using a Vexcel VX4000 Image Scanning System. The scanned imagery was aero-triangulated and geo-referenced to the Ramsey County Coordinate System (nonHARN). The imagery was tone balanced so that the color of the imagery was accurate and consistent throughout the entire study area, seamlines were manually selected. Orthophotos were created using elevation models obtained from Ramsey, Anoka, Washington and Dakota Counties. The elevation models were reviewed and edited to represent the terrain conditions of the 2006 aerial photography prior to the ortho-rectification process. The orthophotos were reviewed for geometric and radiometric accuracy as well as tone consistency. Bridges and overpasses were corrected to the appropriate horizontal position and artifacts were removed using Photoshop methods.
