Statewide High-Resolution Vermont Land Cover Data Now Available

03 September 2019

Base land cover and other supplementary land cover layers are now available for download and streaming at the Vermont Open Geodata Portal. The 2016 statewide, high-resolution land cover products are created from a combination of 2013-2017 lidar data and 2016 orthoimagery. Full details about the products, source data, methodology, and limitations are available in the accompanying report and documentation.  

The high-resolution land cover datasets serve as a key component of and addition to Vermont’s Spatial Data Infrastructure that includes orthoimagery, lidar-derived elevation products, and grand list-joined parcel data.

Available products with statewide coverage include:

  • Base Land Cover: A raster product with a 0.5-meter resolution. This layer contains 8 classes: tree canopy, grass/shrubs, bare soil, water, buildings, roads, other paved, and railroads. This is the foundational, “top-down” created land cover product from which supplemental layers below are derived.

  • Supplemental Land Cover: Vector products that include shrub, agricultural, and wetland land cover types as individual layers. These are standalone delineations of base land cover features.

  • Tree Canopy: Vector product that refines the base land cover canopy class into individual tree canopy polygons and classes them as either deciduous or coniferous.

  • Impervious Surfaces: Vector product created through a “bottom up” approach to map surfaces obscured by tree canopy. Includes buildings, roads, other paved, bare soil, and railroad classes.

  • 3D Building “Roofprints”: Vector product of building roofprints from the impervious surfaces layer attributed with height information derived from LiDAR data.
