Title: LandLandcov_TreeCanopy2022.tif

Geospatial_Data_Presentation_Form: remote sensing image

Description:

Abstract:

This Coniferous and Deciduous dataset was derived from high-resolution remotely sensed data -- 2021/2022 NAIP and 2016 LiDAR. Object-based image analysis techniques (OBIA) were employed to extract potential tree canopy and coniferous deciduous trees using the best available remotely sensed and vector GIS datasets. OBIA systems work by grouping pixels into meaningful objects based on their spectral and spatial properties, while taking into account boundaries imposed by existing vector datasets. Within the OBIA environment a rule-based expert system was designed to effectively mimic the process of manual image analysis by incorporating the elements of image interpretation (color/tone, texture, pattern, location, size, and shape) into the classification process. A series of morphological procedures were employed to insure that the end product is both accurate and cartographically pleasing. Following the automated OBIA mapping a detailed manual review of the dataset was carried out at a scale of 1:2500 and all observable errors were corrected.

Purpose:

Coniferous and Deciduous feature class developed as part of land cover mapping for the Updated High-Resolution Land Cover Mapping for Vermont.
