Two GSE Ph.D. students are award winners at PECORA 20

Poster presentations from two GSE Ph.D. students took the 2nd and 3rd place awards in the student competition at PECORA 20 (http://pecora.asprs.org/). About 400 people from government agencies, academia, and geospatial industries attended the 20th William T. Pecora Memorial Remote Sensing Symposium that was held in Sioux Falls, SD 13-16 November 2017.

Yenni Vetrita earned a 3rd place award for her poster entitled “Assessing Three Satellite-derived Burned Area Products and Combining with Medium Resolution Data for Characterizing Peatland Fires”. Former GSCE senior scientist Dr. Mark Cochrane is her dissertation advisor and Dr. Xiaoyang Zhang is the chair of her advisory committee.

Lan Nguyen earned a 2nd place award for his poster entitled “Detecting Land Change Using Land Surface Phenology Modeling: An Application to the Dynamic Northern Great Plains”. Dr. Geoff Henebry is his dissertation advisor and chair of his advisory committee.

Congratulations to Yenni & Lan for their winning presentations!
