AGB Post-processing Results: USGS_3County2014

Applying landcover masks to USGS_3County2014 LiDAR-year AGB surface.

Target Year: 2016

Model: linmod

AGB + Mask Information:

Input AGB: https://github.com/cafri-labs/current-agb

Models: https://cafri-labs.github.io/model-updates/2021_02_03_big_tune.html

CCAP Mask:

Mask:
- Developed high intensity (2)
- Developed medium intensity (3)
- Developed low intensity (4)
- Developed open space (5)
- Open water (21)
- Palustrine aquatic bed (22)
- Estuarine aquatic bed (23)

LCMAP Base Mask:

Mask:
- Developed (1)
- Water (5)

LCMAP Update Mask:

Stack annual land cover change rasters (from:to in each cell)
Convert the annual land cover change stacks to boolean stacks:
- 0:
  - Non-water | non-developed -> water | developed
  - Tree-cover -> non-tree-cover
- 1:
  - Everything else
If the number of layers in the stack >= 2:
- Any cell with at least two consecutive 0s anywhere in the stack is collapsed to a 0
- All other cells are collapsed to a 1
