Welcome to the 2020 TUgis Conference. TUgis: Maryland’s Geospatial Conference is a cooperative undertaking of three primary partners—Maryland State Geographic Information CommitteeMaryland Department of Information Technology, and Towson University. TUgis is dedicated to growing and empowering the GIS community throughout the Mid-Atlantic. The annual conference connects the Maryland GIS community to new ideas and trends and offers ample opportunities to find ways to collaborate.

Drone laser scanning (DLS), or UAV-based lidar, provides ultra-high-resolution point clouds (greater than 400 points per square meter) of the environment, which allows scientists and engineers to collect detailed information about both the topography and vegetation. For this study, six DLS surveys were conducted over a two-year period (2017 to 2019) for a reach of Stroubles Creek, located downstream of Virginia Tech's main campus in Blacksburg, VA. This reach underwent a stream restoration in 2010 and is continuing to evolve and change since having its streambanks reshaped and floodplain vegetation planted. Three lidar metrics were generated to represent different aspects of the floodplain vegetation: height, roughness, and density. The change in these metrics both seasonally and annually were then quantified by calculating DEMs of difference. Simple data processing pipelines using ArcGIS and Python scripting were used to help automate these workflows
