GTBX
(GOCI-ll ToolBoX)
GTBX is an extension plugin of the SNAP program, developed by the European Space Agency (ESA), to analyze and process data from GOCI/GOCI-II.
SNAP is an open source common architecture, suitable for using earth observation data. Access the following link to check the details and download the program.

Role of GTBX
- Display GOCI data (L1B?L2 HDF-EOS5 file)
- Display and analyze GOCI/GOCI-II data (L1B?L2 NetCDF4 file)
- Search ad download desired data
- Search and download products with the condition of the tag, type, column, or attribute of products
- Select some dataset or an interested area of the products based on the Thredds Data Server (TDS) and download the data
- Process L2 products
- Process the real-time L2 products processing function of the terrestrial system of the Korea Ocean Satellite Center in SNAP offline in the same way
- Execute the Docker Container through the SNAP Graph Builder (the root authority is required)
