Prior Events

Fresno Technical Session — January 25, 2018.

A PSW technical session was held at CSU Fresno on the eve of their Geomatics Conference which continued on January 26-27.

Date:           January 25, 2018

Time:           6:00 – 9:00 p.m.

Location:    California State University, Fresno, Industrial Technology Room 160

There were two excellent presentations given during the evening: Dr. Riadh Munjy and Dr. Jack Paris.

Ground Control Distribution for UAS Imagery

Dr. Riadh Munjy: Chairman of the Civil & Geomatics Engineering Department at California State University, Fresno.

Unmanned aircraft systems (UAS) imagery has been used in various mapping applications.  For light weight UAS, the imagery presents various challenges to automatic aerial triangulation software. Large photo scale variations due to low flying height require special matching algorithms. Poor GPS data which usually exists on light weight UAS present another challenge for the automatic aerial triangulation. Also, many light weight UAS imagery exhibit large roll, pitch and yaw rotation compared to traditional vertical photogrammetric imagery.

Drones for Agricultural Mapping and Monitoring . . . the Camera Matters and the Processing Matters

Dr. Jack Paris.

Dr. Jack Paris is an active remote sensing scientist with more than 50 years of experience: Apollo photography (Texas A&M), Lockheed Electronics (NASA Houston … Landsat 1), University of Houston at Clear Lake (Asst. Prof.), NASA, JPL, Fresno State (Research Prof.), CSU Monterey Bay (Research Prof.), DigitalGlobe (helped developed WorldView 2), in private practice since 2004, living in Clovis since 2008. Dr. Paris has developed imaging processing and information extraction algorithms for multispectral images, radar images (Space Shuttle Imaging Radar), and hyperspectral images. For the past three years, Dr. Paris has concentrated on the goal of rapid processing of multispectral imagery taken from drones by rig-camera systems. Dr. Paris is an Emeritus Member of ASPRS. His formal education was at Texas A&M University (B.S. physics and Ph.D. meteorology) and Univ. of Washington (atmospheric sciences).

In addition to the presentations listed above, there was a light meal provided prior to the session to allow time for networking.

Thank you to all who joined us  at the session in Fresno!
