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,and railroads polygons from a combination of 2016 LiDAR and 2016 Orthoimagery. The resultant Impervious polygons were then subjected to a manual review at a scale of 1:2500. A further processing task was conducted to detect rocky outcrops on the tops of mountains, which are classified as Bare Soil in this dataset.

Purpose:

Impervious polygons developed as part of the Vermont High-Resolution Land Cover mapping project.
