ASPRS Northern California Region Technical Session

ASPRS Northern California Region

Meeting Announcement: Northern California Chapter
Sacramento Technical Meeting
September 26, 2013 - Thursday Evening from 6:00 to 9:00 pm

Back to Our Roots: Aerial Photography
Bill Calmes - Cartwright Aerial Surveys
Curtis Holmes - American Aerial Surveys, Inc.
Lorraine Amenda, PLS, CP - Towill, Inc.

Would you like to learn about planning an aerial photography mission? What are the logistics involved with putting an aircraft, a camera and the crew up into the air? How do they stay on line and get moving objects on the ground, centered in the camera lens? What's involved with processing film and making prints? Do you know the pros and cons of film versus digital imagery?
Even with today's high-tech world of satellites and digital imagery, mapping professionals still need to know how to go about planning for and acquiring airborne aerial photography. Knowledge of aerial photographic equipment and operations is a skill set that is not really covered in college, but which is needed once young mapping professionals get out into the working world.

Arrive early at 5:30 pm if you'd like to munch or network. This is a chance to get out of the office and mingle with colleagues you've been working with over the Internet and via email. Meet your new officers and other members of our Northern California and Nevada region. If you are not a member of ASPRS and are interested in aerial photography, you are welcome to attend.

Thanks to Caltrans GeoMetronics, Office of Photogrammetry, for hosting the meeting.
An RSVP is required to attend the meeting due to Caltrans building access requirements after hours
