Service Description: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 impervious, and railroad 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.

Subject: Impervious polygons developed as part of the Vermont High-Resolution Land Cover mapping project. It is derived from the Base Land Cover 2016 layer and includes buildings, roads, other impervious, and railroad features from a combination of 2013 - 2017 LiDAR and 2016 Orthoimagery data.
