Name: Polygonal Anthropogenic Disturbances 2020

Display Field: Class

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: Depending on their geometric descriptions, anthropogenic disturbances (as identified from 30m resolution landsat imagery at a viewing scale of 1:50,000) are represented by a line or polygon. Polygonal disturbances include: cut blocks, harvest, agriculture, built-up areas, oil and gas facilities, mines, well sites and unknown features. Included here are polygonal disturbances i) identified in 2010 that were also visible in 2015 ii) identified as new in 2015 iii) obtained from CFS (harvest polygons for 2015-2020) and added prior to digitization and iv) identified as new in 2020.
