This INSPIRE compliant data comes from the source data CARBIOSOL - Uncertainties of Total Organic Carbon Contents - period 2004-2014. It takes up the uncertainty associated with the calculation of stocks and modelling for predicted TOC stocks in soils under crops and meadows in Wallonia for the period 2004-2014. It is therefore a modeling of the prediction error. As part of the CARBIOSOL project (UCL - ULg - DGARNE), a raster data layer of 40 meters of resolution of total organic carbon stocks of soils under crops and grasslands was generated by spatial modelling. This model was developed for each type of land use of interest (crops and permanent grasslands). For each land use, a Generalised Additive Model (GAM) has been adjusted to a calibration set containing two thirds of the observation points concerned. It was then validated on the remaining third. For more details on the modeling implemented under CARBIOSOL, please refer to the metadata sheet documenting the data layer series. Prediction uncertainties for stocks are calculated according to the recommendations of the GlobalSoilMap project (Heuveling, 2014 - see genealogy). Mapping of modeling uncertainties associated with predicted TOC stocks is a spatially continuous raster layer on soils under permanent crops and grasslands with a resolution of 40 metres. The uncertainty in each pixel is expressed as a relative percentage (% relative to the predicted median value). Prediction error modeling is a potential error that allows a better interpretation of the final cartographic products generated by the CARBIOSOL project. The mapping of total organic carbon stocks should therefore be read in conjunction with the uncertainty map. Significant uncertainty reflects a less reliable prediction and therefore greater caution in the interpretation of values INSPIRE - CARBIOSOL - Uncertainties of Total Organic Carbon Contents - period 2004-2014 in Wallonia (BE) High value dataset aardewerk be biologie biologie-du-sol carbiosol carbone carbone-organique carbone-organique-total carbosol chimie-des-sols co2 cosw cot cycle-du-carbone dégradation-du-sol déterioration-du-sol digital-soil-mapping dtm dynamique-naturelle fertilité-du-sol forêt horizon-de-sol horizon-de-surface matière-organique modélisation organisme-du-sol prairie régional sol sols structure-du-sol teneur-en-carbone https://org.belgif.be/id/CbeEstablishmentUnit/2204322327 Helpdesk carto du SPW (SPW - Secrétariat général - SPW Digital - Département Données transversales - Gestion et valorisation de la donnée) https://geodata.wallonie.be/id/c7caec6d-9393-414b-a5c7-362521720b08 WMS_SRVC http://data.europa.eu/88u/dataset/https-geodata-wallonie-be-id-8279ac41-903a-4196-8d5c-8fa836c949ea https-geodata-wallonie-be-id-8279ac41-903a-4196-8d5c-8fa836c949ea https://geodata.wallonie.be/id/8279ac41-903a-4196-8d5c-8fa836c949ea fr This INSPIRE data layer shows the uncertainties of the Total Organic Carbon content in soils under crops and permanent grassland in Wallonia in the period 2004-2014.
