Abstract
Abstract. Recently, several technologies have emerged to address the need to process and analyze large volumes of Earth Observations (EO) data. The concept of Earth Observations Data Cubes (EODC) appears, in this context, as the paradigm of technologies that aim to structure and facilitate the way users handle this type of data. Some projects have adopted this concept in developing their technologies, such as the Open Data Cube (ODC) framework and the Brazil Data Cube (BDC) platform, which provide open-source tools capable of managing, processing, analyzing, and disseminating EO data. This work presents an approach to integrate these technologies through the access and processing of data products from the BDC platform in the ODC framework. For this, we developed a tool to automate the process of searching, converting, and indexing data between these two systems. Besides, four ODC functional modules have been customized to work with BDC data. The tool developed and the changes made to the ODC modules expand the potential for other initiatives to take advantage of the features available in the ODC.
Highlights
In recent years, the amount of Earth Observation data freely available has grown, motivated by technological advances in acquisition and storage equipment and space agencies’ policies that make their data repositories available
We hope that more tests will be done on the modifications made to the modules to be sent to the official Open Data Cube (ODC) repositories
It is expected that the adaptation or even the development of new algorithms will be performed for this tool
Summary
The amount of Earth Observation data freely available has grown, motivated by technological advances in acquisition and storage equipment and space agencies’ policies that make their data repositories available. A Spatial Data Infrastructure (SDI) provides an environment that allows people and systems to interact with technologies to foster activities for using, managing, and producing geographic data (Rajabifard and Williamson, 2001). SDIs have been built using technological components that implement standards proposed by Open Geospatial Consortium (ODC) and Organization for Standardization (ISO) to represent, store and disseminate spatial data. Even with these standards, most current SDIs are focused on EO data sharing and dissemination in the form of individual files through web portals and HTTP, FTP, and SSH protocols (Muller, 2016)
