Section 3. VM0047 Stocking Index (SI) – Minimum Requirements and Attestations
Please provide details about the technical specifications of the Stocking Index (SI) data product your organization plans to provide project proponents (PPs).
Note: Specific project level documentation may also be required during validation/verification as requested by the PP, Verra, or VVB.
3.1 Spatial Resolution
The SI dataset provided for projects must have final spatial resolution finer than 30 m × 30 m (i.e., pixel size ≤ 30 m) for all years provided. Describe your source data and processing steps that ensure the delivered SI maintains this resolution.
Short explanation/description of the spatial resolution of the SI data product(s) your company provides: *
Links to supporting documentation (optional)
3.2 Temporal Resolution
The SI must be available at least annually, covering relevant baseline and monitoring years for the project. Describe the cadence at which the SI is produced and any constraints or gaps.
Please provide a short explanation of the temporal resolution of your data products (≤200 words): *
Links to supporting documentation (optional)
3.3 Seasonality Control
Optical imagery used to generate the SI should be constrained to a consistent seasonal window each year to limit phenology and atmospheric effects. Describe the seasonal window(s) and quality filters you apply.
Short explanation (≤200 words): *
Links to supporting documentation (optional)
3.4 Correlation with Aboveground Biomass (AGB)
Provide evidence that your SI (or equivalent metric) is correlated with AGB in the forest types or ecoregions you support. Indicate how you will demonstrate project‑specific correlation for validation (e.g., local plots, literature, cross‑validation).
Please provide a short explanation of your process for assessing correlation of your SI with AGB for unique project locations (≤200 words): *
