CAFRI Labs: Post-Processed (2019) LiDAR-year AGB Surfaces

Lucas Johnson

Description

LCMAP Collection 1.1 Data

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
