Annie Trambley and Tarika Hanawalt: WSI

Modeling with Lasers

Website: WSI

Airborne LiDAR (Light Detection and Ranging) is an active remote sensing technology that utilizes lasers for the cost-effective collection of highly detailed and accurate terrain surface data. Heat Source is an open source modeling program developed to model physical and thermal salmon habitat using remotely sensed TIR (thermal infrared radiometry) and LiDAR data as model inputs. The Heat Source program can be used to predict how stream temperature will be affected by changes in climate and anthropogenic uses.

Tarika and Annie will give an overview on the basics of LiDAR and how remote sensing technology improves the effectiveness of stream temperature modeling as well as why this technology matters to the wellbeing of fish. The presentation will include water quality management in Oregon, LiDAR acquisition and calibration, and Heat Source modeling applications.

Tarika recently received his BS in Environmental Engineering from Portland State University and now works as a water quality analyst for WSI, in downtown Portland. He grew up in Port Townsend, Washington but has lived in Portland for the last 14 years, which is the farthest South he has ever lived in his life. When not analyzing laser data he enjoys fishing, building boats, eating tacos, and sleeping in.

Annie Trambley is a Water Quality Analyst at WSI. She has a degree in Environmental Engineering from PSU, with a focus on surface and subsurface contaminant transport. Her hobbies include composting, cooking, clamming and scavenger hunts. She hopes to one day tour the largest sewage treatment plant in the world, just outside of Mexico City.
