Purpose / Description FLM is a series of script tools for facilitating the high-resolution mapping and studying of forest lines via processing canopy height models (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.

Development History

  • December, 2021: V1.2.0 public release, beta test, and this online documentation by Richard Zeng
  • February, 2020: Beta public release, beta test, and this online documentation by Gustavo Lopes Queiroz.
  • November, 2019: Workflow overhaul (least cost corridor & multiprocessing) by Gustavo Lopes Queiroz.
  • November, 2018: First version in Arcpy by Silvia Losada.
  • May, 2018: Initial concept (least cost path with ArcGIS model builder) by Sarah Cole and Jerome Cranston.

Changelogs There are major changes to the tools:

  • File based approach is switched to memeory based to speedup the processing
  • ArcGIS Desktop is no longer supported. ArcGIS Pro is the only platform supported now.
  • Added Pre-tagging and Vertex Optimization tools to automate data preparation.
