Important notes to the user:
The GDB support of KOMPSAT2 DIMAP data products is "read-only".
K2DIM data sets can be distributed on CD or DVD. On disk, the data is organized in a special directory structure. GDB uses this directory structure and the file names to identify the data product type. Therefore, to preserve compatibility with GDB, the directory structure and file names must not be altered when the data is copied over to another location from the CD or DVD.
To open a KOMPSAT-2 DIMAP data set, select the metadata file (K2DIMAP.xml).
| Data product | Data returned | Details |
|---|---|---|
| K2DIM image data | Four raster channels | The MSC multispectral image contains a green band, a blue band, an alpha band, and a red band. |
| K2DIM image data | One raster channel | Contains the MSC panchromatic image |
| Ephemeris data | One orbit segment | GDB imports ephemeris data as an orbit segment. This segment contains information about the satellite position, satellite attitude, IFOV, projection, sensor, and orbit. |
| RPC data | One binary segment | GDB imports a Rational Function model as a binary segment. |
| General information and metadata | Text segment | The K2DIMAP data product also includes a text file that contains general information. GDB imports this data as a text segment. |
