Access to data is based on a principle of full, open and free access as established by the Copernicus data and information policy Regulation (EU) No 1159/2013 of 12 July 2013. This regulation establishes registration and licensing conditions for GMES/Copernicus users.

Free, full and open access to this data set is made on the conditions that:

1. When distributing or communicating Copernicus dedicated data and Copernicus service information to the public, users shall inform the public of the source of that data and information.

2. Users shall make sure not to convey the impression to the public that the user's activities are officially endorsed by the Union.

3. Where that data or information has been adapted or modified, the user shall clearly state this.

4. The data remain the sole property of the European Union. Any information and data produced in the framework of the action shall be the sole property of the European Union. Any communication and publication by the beneficiary shall acknowledge that the data were produced “with funding by the European Union”.

Statement

The Forest Type 2018 status layer at 10m spatial resolution is mainly based on the primary status layer Dominant Leaf Type 2018, which was produced by a hierarchical spatio-temporal classification of time features derived from Sentinel-2A+B time series (Level-2A data) using a Random Forest (RF) classifier with 500 trees. The default time window ranges from 01-03-2018 to 31-10-2018 and was adapted to regional conditions where needed. In total, 147 statistical time features have been calculated using more than 500,000 samples, automatically collected from the LUCAS 2018 database and various CLMS products plus additional manual sampling. First, a binary Tree Cover Mask (TCM) with 2 classes (all non-tree covered areas / tree cover) has been generated. Various post-processing steps have been applied in order to improve the quality of the mask (e.g. correction of omission errors caused by the topographic overcorrection within the native Sentinel-2 Level-2A input data). Subsequently, the dominant leaf type has been separately classified within the confines of the Tree Cover Mask. In order to generate a forest type product following the FAO forest definition, a minimum mapping unit of 0.5 ha has been applied to the initial Tree Cover Mask considering a 10% tree cover density threshold and with all pixels in agricultural and urban context (as provided by the FADSL) removed. Subsequently, filtered non-forest patches smaller the MMU have been filled with the neighbouring leaf type information using a 9x9 circle filter. In case of tree covered pixels smaller 10% TCD being present in those non-forest patches, the original Dominant Leaf Type information is kept. National FTY products are derived through reprojection and might show a broken MMU.

For the 100m aggregated layer, the 100m (aggregated) pixel is assigned the class from the corresponding 10m pixels value covering more than 50% (rule-based spatial aggregation).

Quality assurance follows the ISO 9001:2015 standards for Quality Management and comprises of dedicated procedures of quality checks (QA breakpoints) during implementation of the production chain, in order to keep persistent control over the various stages of production, assure fitness-for-purpose of the end-products and that all quality requirements are fulfilled. Priority has been given to the target thematic accuracy to be achieved by each product, as well as to the issues of product consistency (spatial, thematic, temporal) and homogeneity. Quality Assessment: The quality assessment has been performed according to INSPIRE Data Specifications. The data quality elements considered are: (i) Completeness, (ii) Logical Consistency, (iii) positional accuracy, (iv) Thematic Accuracy, (v) Temporal quality and (vi) Usability.

Geometric accuracy (positioning scale): Less than one pixel (10m) according to ortho-rectified satellite image base (Sentinel-2 Level-2A) delivered by ESA.

Thematic accuracy at pan-European level: determined by the accuracies of the input source layers Dominant Leaf Type, Tree Cover Density and Forest Additional Support Layer (including CLC 2018 and HRL Imperviousness 2018 data). The thematic accuracy of the FTY product has not been assessed.
