MNSTAC Monthly Forums
Monthly forums address issues in urban forestry, arboriculture, and research. Forums are typically held on the third Thursday of the month.
Urban Tree Canopy Mapping and Measuring using High-Resolution Remotely Sensed Data
Presenter: Trevor Host, University of Minnesota
Urban tree canopy is a critical and rapidly changing component of the city landscape. Tree canopy provides benefits that range from ecological to economic to aesthetic. Obtaining landscape scale information on the status of tree canopy is costly and time-consuming on the ground but can be completed much faster and more cost-effectively from the air. In this research, we used airborne remotely sensed data to precisely observe the abundance, condition, and changing status of urban tree canopy. High-resolution optical imagery and lidar datasets were used in combination to update and assess change of urban tree canopy in the seven county Twin Cities Metropolitan Area. Object-based image segmentation using eCognition software was able to automate detection of isolated tree crowns.

The front desk tells me that folks should jot down their car license plate number and it will take just a minute or two for them to get past them, and down to the lower level.
