Data requirements
Shapefile
Required
- Minimum 100 individual trees
- Option A (preferred): Polygon shapefile — one polygon per tree crown
- Option B: Point coordinates — only accepted if DBH or tree height is provided per tree
- All trees in the image should be delineated; partial delineations accepted (mention in notes)
- Attribute column named exactly
Specieswith Latin names (e.g. Picea abies) - Genus sp. for unknown species of a Genus (e.g., Picea sp.); Dead trees should be named: Dead tree
- CRS: WGS 1984 UTM — must match imagery
COCO JSON
Optional
- COCO-format .json annotation file
- Include matching image files (PNG / JPG / TIFF) and label .txt files
- Add metadata describing class names and dataset contents
TIFF Imagery
Required
- Format: GeoTIFF (.tif / .tiff)
- Resolution: ≤ 10 cm (~3.94 in) spatial resolution
- Band order: R → G → B → I (NIR last); RGB-only accepted
- One orthomosaic per site per year preferred; cropped plot clips accepted
- Note the acquisition date in your submission notes
- CRS: WGS 1984 UTM (projected; zone based on location)
Other
Optional
- Measurement date (multi-temporal datasets welcome)
- Tree metrics: DBH (cm), height (m), social status (dominant / co-dominant)
- Forest density: trees/ha, basal area/ha
- Defoliation / mortality % per tree (0 = healthy, 100 = dead)
- Environmental data: elevation, slope, aspect, climate, soil
- Extra imagery: multispectral, hyperspectral, ground panoramas, LiDAR point clouds
