Dataset
High-Resolution map of forest above-ground carbon storage Products
1. Overview
The Earth Observation Center (EORC) of the Japan Aerospace Exploration Agency (JAXA) has released a map of forest above-ground carbon stocks (=biomass)
in Japan as a result of the joint research "Estimation of Forest Above-Ground Biomass Using Satellite Data"
(Principal Investigator: Professor Tomomichi Kato, Graduate School of Agriculture, Hokkaido University, Japan) approved by
"the Third Research Announcement on the Earth Observation".*
In this research, a high-resolution biomass map was generated by constructing a model using machine learning based on satellite data from JAXA's
“Daichi-2” (ALOS-2), the European Space Agency's Sentinel-2 optical satellite, and other data, as well as above-ground biomass measurements data by airborne laser surveys (LiDARs).
The newly created map of forest above-ground carbon stocks consisting of the forest above-ground biomass, timber volume, and tree height, is available on this website,
allowing anyone to check the forest above-ground carbon stocks in any region.
In the future, further improving the accuracy of the maps, creating maps for multiple periods, and creating maps for other countries will be planned.

4. Note for data use
This dataset is available to use with no charge under the "Terms for Use".
For commercial use, please contact us with the address shown in the final section.
A part of this dataset may include missclassification. If this map is very different from the current land use, please contact us too.
5. About data utilization
"Japan Biomassmap Products" has a GeoTIFF data format, and software such as image processing, remote sensing, GIS, etc. is required for display and use.
You can use software released free of charge, for example, QGIS It is widely used software for the general public.
Please note that the free software introduced here is only an example, and it is not necessarily guaranteed by JAXA. Please understand that JAXA can not answer any questions about software. Please refer to these and use "Japan BiomassMap Products".
