NCGS Sampling Designs

Pre-release. This site describes standard version 0.7.0-dev, which is in development and may change before version 1.0.0.

How a monitoring plan observes its strata: a census observes every tree individual (the NCGS-M001 default); a sample observes the strata it names, under a methodology that defines the sample. Declared in the project design’s monitoring plan (ADR-0012, ADR-0016).

Census

Every tree individual in the planted strata is observed on each visit at a horizon.

Sample

Only the strata the plan names are sampled; the sampling frame and size are the applied methodology’s.

This page explains the standard and does not decide conformance: only the released corpus does. It describes glossary/horizons-and-strata.ttl at standard version 0.7.0-dev.
