Forest Typology (ForTy) 2020 v1

This is a mirror of Forest Typology 2020 (v1), a global 10 m resolution map of forest typology for the 2020 baseline from NatureTrace. The dataset categorizes all land into five forest categories and other land. We unzipped the archives, kept every tile unchanged, and added a STAC index for this mirror.

Producer and source

• Producer: Nature Trace (Neumann, M., et al.). We are the mirror, not the author.
• Source: Figshare+ article 32288616, 613 ZIP archives, one per MGRS (Military Grid Reference System) cell. Version DOI https://doi.org/10.25452/figshare.plus.32288616.v1.
• Companion preprint: https://doi.org/10.31223/X58R27

Changes to Original Publication

• We did not change the pixel data. Every tile already validates as a COG (Cloud-Optimized GeoTIFF). We mirror every tile unchanged. We verify integrity against the Figshare MD5 of each archive.
• The archives are unzipped and the tiles are addressed via their MGRS cell.
• We added the STAC-geoparquet index.

Coverage

Bands

The primary record consists of a 5-band raster layer. Each band has a valid range of 0 to 250. The NoData value is 255. Each band is a class probability. Multiply by 1/250 to get the probability in [0, 1]. There is an implicit sixth band. This band gives the probability of "other land use".

The categorical map is the argmax over the six classes.

How to read

The example below finds tiles through the STAC index, then reads the COGs through the source.coop proxy:

Each STAC Item carries the footprint in EPSG:4326 and the native EPSG code in the projection extension. The class table is in the classification extension.

Known limitations

• The tiles do not form one combined array. The CRS changes with the UTM zone. To make a mosaic, reproject the tiles when you read them.
• The tile rows run bottom-up. Call da.sortby("y") for a north-up view.
• 0 is a real value. Mask on 255, not on 0.
• There is no public icechunk store for this product.

Catalog

This product is also a Portolan catalog: STAC 1.1 metadata over the same files, which a STAC client or an agent can read without a server.
