Brazil Data Cube is a project that is being developed by the Brazil’s National Institute for Space Research (INPE), since January 2019, that aims to create multidimensional data cubes of analysis-ready from medium-resolution Earth observation images….
The researchers presented the project and participated in technical discussions with leaders of similar initiatives and projects in other countries to build Earth observation data cubes.
The session was mediated by Marie-Francoise Voidrot, Europe Director, Innovation Program – Open Geospatial Consortium, OGC and Prof. Thierry Ranchin, Director of the Observation, Impacts, Energy Center in MINES – ParisTech – PSL University.
Besides the Brazil Data Cube project, other initiatives as the “Swiss Data Cube”, “Data Cubes for Australia and Africa” and “Euro Data Cube” were presented by the researchers Gregory Giuliani (Head/Project Leader – Digital Earth Unit/Swiss Data Cube), Brian Killough (Head, CEOS Systems Engineering Office – NASA Langley Research Center), Fang Yuan (Assistant Director – Digital Earth Australia) and Grega Milcinski (CEO – Sinergise).
The GEO Data and Knowledge Week symposium, which would take place in Pequin, China, in February 2020, was postponed due de Coronavirus pandemic. It gave way to the GEO VIRTUAL SYMPOSIUM 2020 that will take place between the 15th and the 19th of June 2020 through virtual discussions and interactive webinars.
Dr. Karine Ferreira and Dr. Gilberto Ribeiro, represent the Brazil Data Cube project in a presentation on Data Cubes, along with other global initiatives, on June 16, 2020.
The “I Internal Workshop of the Brazil Data Cube (BDC) project” aimed to present results and discuss the methods that are being applied in the generation of data cubes. The BDC team, researchers and collaborators from other environmental monitoring projects at INPE, which will use the computational infrastructure and data cubes generated by BDC, attended this workshop. The event is part of the activities planned under the Environmental Monitoring of Brazilian Biomes (FA-BIOMAS) project, funded with resources from the Amazon Fund, through the BNDES and FUNCATE financial collaboration No. 17.2.0536.1.
The event occurred on December 19, 2019 at INPE, where there were nineteen presentations separated into two parts and seven sessions in total. The first part dealt with gnereal information about the Brazil Data Cube and its applications. In the first session, the methodologies used to generate the data cubes and the Brazil Data Cube portal were presented. The theme of the second session was about the web services being used in the BDC project. They were: the Metadata Database Model, Spatio Temporal Asset Catalog (STAC), Web Land Trajectory Services (WLTS) and the Web Time Series Service (WTSS). The third session was about system applications: Open Data Cube initiative with the BDC project, Forest Monitor, SITS package developed in R, and examples using data cubes with Jupiter Notebooks. The fourth session was dedicated to the application of the data cubes generated by members of the project. The classification results were presented using the Sentinel data cube for the Amazon, CBERS data cube classification for the Cerrado, segmentation using superpixel and selection of vegetation indices and samples.
The second part of the workshop was dedicated to projects that will use the data cubes generated by the BDC. In the fifth session, there was a presentation about the FIP/CERRADO project. The TerraCLASS Cerrado project, the PRODES project, and the TerraBrasilis platform were introduced in the sixth session. The last session the initiatives being developed by INPE Applied Computing masters and doctoral students were discussed: TerraBrasilis Research Data, time series clusters using Growing Self-Organizing Maps (SOM) and GGSOM Tool; SITS-Rep package: automation of reproducibility of land use and land cover analysis; and application of Sentinel-2 for Agriculture Monitoring (Sen2Agri).
At the end of the event there was a celebration barbecue.
