CAFRI Labs: Big Tune Map Accuracy v2 - Pooled+

Lucas Johnson

Description

Riemann et. al.

Previous version

Branch used to produce this document: big-tune-pooled+

Coverages included

NYSGPO_WarrenWashingtonEssex_2015
NYSGPO_CayugaOswego_2018
NYSGPO_AlleganySteuben_2016
USGS_3County2014

FIA plot inclusion criteria

Training plots, testing plots, and plots not deemed satisfactory for modeling (due to AGB v LiDAR, or p_area_diff) were included in this assessment.
Tier 1 and 2 plots only.
All subplots must be sampled.

Masking

LCMAP Collection 1.1. data was used to develop masks for each LiDAR coverage included in the assessment, matching LCMAP products to LiDAR-AGB surfaces by year. E.g. LCMAP’s 2014 surface was used to mask the LiDAR-AGB surface for USGS_3County2014.

NOTE: Masked AGB pixels are set to 0, and included in the agreement assessment just as any other AGB pixel.

Masked classes:

1: Developed
5: Water
