It is with tremendous sadness that we pass on the news that Dennis Trombatore passed away on Saturday, July 18, 2020 after a long illness. Dennis was a long-time Geonet participant and the long-term Chair of the GeoRef Advisory Committee. His expertise and his wit will be sorely missed and fondly remembered. An eloquent tribute to Dennis has been posted on the University of Texas website at Dennis Trombatore.
