Name: Central Southeast 2020

Display Field: nDSM_MAX

Type: Feature Layer

Geometry Type: esriGeometryPolygon

Description: This polygon dataset is derived from Landsat reflectance and LiDAR elevation data. The polygon boundaries represent "image objects" that were derived using eCognition image segmentation software. The software groups image pixels into contiguous segments based on spectral reflectance. The attributes for each polygon are then calculated from the LiDAR crown height layer. Attributes include maximum, minimum, and mean elevation above the ground and standard deviation within each polygon. Elevation is in meters. This dataset incorporates Landsat imagery collected in 2018 and 2020. LiDAR data were collected in 2011 and 2012.

Copyright Text: These data were developed by NH GRANIT using funding from the New Hampshire Space Grant Consortium.
