Flight Planning and Execution
The following flight patterns and execution are recommended:
§ For single building or small area collection, use a circular flight pattern, with the target area in the center of the image from all perspectives.
§ For large scale collection, use a grid pattern which allows for efficient area collection with the goal of creating 3D products.
§ For nadir cameras with a field of view of approximately 60 degrees, tilt the camera 10-15 degrees forward to achieve the necessary 40-45 degree oblique perspective in all directions.
§ Maintain a frontal (vertical) overlap of 75 - 90% (recommended - 80%).
§ Maintain a side (lateral) overlap of 70 - 90% (recommended - 80%).
