The Assesscarbon project (Feb 2020 – Feb 2021) developed and demonstrated at a pre-operational level an approach for large area forest biomass and carbon modelling, combining ground reference data, Sentinel-2 imagery and primary production modelling.
See project description below, or read about the progress of the project in these blog posting:
- Assesscarbon laying the foundation for scalable large area carbon pool and flux modelling in Forestry TEP (20.4.2020)
- Assesscarbon project ready to start implementing biomass and carbon modelling pipeline into Forestry TEP (9.9.2020)
- First large scale forest variable maps processed in Forestry TEP for the Assesscarbon project (24.11.2020)
- Assesscarbon successfully demonstrated large area forest biomass and carbon mapping in Forestry TEP (4.3.2021)
The overall goal of the project is to develop a foundation for a novel approach to derive large area biomass and carbon pool and flux estimates and forecasting in a scalable fashion on an online platform. The project is coordinated by VTT Technical Research Centre of Finland and funded by European Space Agency (ESA) under the EO Science for Society Permanently Open Call funding mechanism. It will run from February 2020 to January 2021.
The general outline of the technical design can be seen in the figure. The main input data for the project will be European Space Agency Sentinel-2 satellite data, forest plot measurements and climatic datasets. The Sentinel-2 mosaics will be created by Terramonitor (Satellio Oy)using their novel image mosaicking approach. This image composite is used together with field sample plots (Finnish Forest Centre) to create forest variable estimation models. Finally, dynamic forest primary production variables are modelled using the forest structure variables and climatic data.
The forest structural variable models will be based on the Probability software package developed by VTT Technical Research Centre of Finland. It contains three different parts, which together form a comprehensive package of classification/estimation tools combining field data with satellite imagery. The primary production modelling will be based on the PREBAS models developed by the University of Helsinki. The models will be further developed utilizing multi-temporal observations. The practical processing of the primary production estimates for the area of interest will be carried out by Simosol Oy.
The demonstration will be conducted on the Forestry TEP. Forest structural variable and primary production information will be produced for a test area covering the entire Finland and the Russian boreal forests until the Ural mountains. All components of the project will be implemented in a manner that enables scalable execution of the models in Forestry TEP environment. The chosen approach will utilize the Sentinel-2 tiling structure as the building blocks. All software components are redeveloped to enable processing of a given number of Sentinel-2 tiles in a coordinated manner, in order to produce consistent results over large interest areas.
