Global Tree Inventory & Carbon Data System
DendroGeo turns field measurements of individual trees (girth/DBH, height, species, GNSS position, photo evidence) into allometric carbon-stock estimates (Chave et al. 2014) and 10 m land-cover context for urban parks — with moderator approval, geofencing, Monte-Carlo uncertainty and fully disclosed QA/QC in reproducible scientific reports (DGR).

Every record carries point ID, species (canonical dictionary with sourced wood density ρ), DBH, height, photo evidence and GNSS position. Raw field values are preserved (e.g. girth_cm) — derived values never overwrite the evidence.
⚖️ Carbon with disclosed uncertainty
AGB = 0.0673·(ρ·D²·H)^0.976; roots = 0.26·AGB; carbon = 0.47·biomass. Monte-Carlo (correlated model error, CV 22%) yields 95% confidence intervals per report.
🛰️ 10 m land-cover context
ESA WorldCover tiles are intersected with the park polygon (area-weighted border cells), with an area-balance QA gate (≤0.5%) before publication.
📄 DGR scientific reports
Each publication is an immutable, hash-verified document: metadata (DataCite 4.7-aligned), analysis fingerprint (engine, git commit, EPSG), QR to the permanent URL, citation & retraction notices. Author = the data contributor.
