Open Data Cube (ODC) was initiated by the Committee on Earth Observation Satellites (CEOS) to provide a solution with new computing technologies, to promote free and open EO satellite data and application algorithms, and to lower the technical barriers for users to exploit the data. Currently, based on ODC infrastructure Taiwan Data Cube (TWDC) is under developing and operating for distributing Analysis Ready Data (ARD) and delivering corresponding application for geospatial data users in Taiwan. In this workshop, not only the system framework and data preparation of ODC will be provided, the practical applications of TWDC will also be introduced. Following topics will be discussed in this workshop: (1) Overview and framework of TWDC, (2) Preparation and usage of ARD in TWDC. (3) Introduction to the applications of TWDC. Through this workshop, the valuable experience and practice of TWDC will be shared and exchanged with international participants to establish localized ODC for foreign countries and third-party international organizations. Under the collaboration with CEOS, hope that the staged achievement of TWDC can be an example in international cooperation projects of ODC.
