Description:
Abstract:
Impervious polygons derived from circa 2016 high-resolution remotely sensed data. Object Based Image Analysis (OBIA) techniques were employed to automatically extract building, roads, other paved, railroads, and compacted bare soil polygons from a combination of 2013 - 2017 Lidar and 2016 Orthoimagery. The resultant Impervious polygons were then subjected to a manual review at a scale of 1:3000.
Purpose:
Impervious polygons developed as part of the Vermont High-Resolution Land Cover mapping project.
Supplemental_Information:
This assessment and development of methods necessary for its conduct were completed by the University of Vermont's Spatial Analysis Laboratory with funding from the State of Vermont Clean Water Fund, Vermont Agency of Natural Resources, Vermont Agency of Transportation, Lake Champlain Basin Program, and the Vermont Center for Geographic Information (VCGI). Tree canopy assessments have been conducted for numerous communities throughout the U.S. where the results have been instrumental in helping to establishing tree canopy goals.

Attribute_Accuracy_Report:
No accuracy assessment was conducted, but the dataset was subject to a thorough manual quality control (QC). Accuracy assessments from previous UTC land cover datasets indicate that the use OBIA techniques in combination with a detailed QC yield an overall accuracy of 95% or better.
