S102 -- S-102 Bathymetric Surface Product

Driver short name

S102

Build dependencies

libhdf5

New in version 3.8.

This driver provides read-only support for bathymetry data in the S-102 format, which is a specific product profile in an HDF5 file

S-102 files have two image bands representing depth (band 1), uncertainty (band 2) values for each cell in a raster grid area.

Note that positive values of depth mean values below the reference surface of the vertical datum. The DEPTH_OR_ELEVATION open option can be set to ELEVATION to expose depth values as elevation values, by negating their sign (i.e. positive values of elevation mean values above the reference surface)

Georeferencing is reported.

Nodata, minimum and maximum values for each band are also reported.

Driver capabilities

Supports Georeferencing

This driver supports georeferencing

Supports VirtualIO

This driver supports virtual I/O operations (/vsimem/, etc.)

Open options

  • DEPTH_OR_ELEVATION=[DEPTH/ELEVATION]: Defaults to DEPTH. Whether to report depth or elevation. Positive values of depth mean values below the reference surface of the vertical datum. Positive values of elevation mean values above the reference surface of the vertical datum (which is the convention used by the BAG driver)

  • NORTH_UP=[YES/NO]: Defaults to YES. Whether the top line of the dataset should be the northern-most one.

    This is the default behavior of most GDAL formats, but the native organization of the data in S-102 products is to have the first line of the grid being the southern-most one. This native organization can be exposed by the driver by setting this option to NO (in which case the 6th term of the geotransform matrix will be positive)
