Purpose / Description

FLM is a series of script tools for facilitating the high-resolution mapping and studying of forest lines (petroleum exploration corridors in forested areas) via processing canopy height models (LiDAR or photogrammetry derived raster images where pixel-values represent the ground-height of vegetation).

Motivation

Given that the process of manually digitizing detailed small-scale (boreal) forest lines is slow and prone to human error, a semi-automated solution is preferred for large-scale application areas. Additionally, high-resolution CHMs allow for improved forest line spatial analysis.
