All vertical photographs are taken with a large format, gyro-stabilized, image motion compensated precision lens mapping camera that is mounted in a fixed wing aircraft. We use high definition black and white, true color, and color infrared films.
Aerial photography costs are based on the number of negatives and flight time required to complete your project. The rate charged includes all materials, preflight planning, mobilizing the aircraft, crew and camera, flying to the project site, taking the photography and returning to Olympia, film processing, film labeling, cataloging of negatives for retrieval, and storage of film in a heat and flame resistant vault.
By interfacing a survey grade GPS receiver with the aerial camera, the WSDOT aerial imaging branch has the ability to record the geographic location of the center of aerial negatives.
Through post-processing of this airborne data with data from ground-based GPS receivers we establish the position of the camera and the center of the lens at the instant of exposure.The established position is related to the center of the negative and is expressed in X&Y coordinates.
To achieve a much higher positional accuracy, a number of survey-grade GPS receivers can be placed near the aerial photo project (at pre surveyed locations).
This can greatly reduce the need for conventional ground control surveys and their associated costs. Please call for technical details and pricing.
