S104 -- S-104 Water Level Information for Surface Navigation Product
Driver short name
S104
Build dependencies
libhdf5
Added in version 3.9.
This driver provides read-only support for water level data in the S-104 format, which is a specific product profile in an HDF5 file.
S-104 files have two image bands representing water level height (band 1) and water level trend (band 2) values for each cell in a raster grid area.
When opening a S-104 file, no raster band is directly available. But a list of subdatasets will be reported, one for each timestamp available in the file.
An actual dataset can be opened through such a subdataset, with a syntax like
S104:"filename.h5":Group_001.
Georeferencing is reported.
Note that the driver currently only supports regularly gridded S104 datasets.
Driver capabilities
Supports Georeferencing
This driver supports georeferencing
Supports VirtualIO
This driver supports virtual I/O operations (/vsimem/, etc.)
Open options
Open options can be specified in command-line tools using the syntax -oo <NAME>=<VALUE> or by providing the appropriate arguments to GDALOpenEx() (C) or gdal.OpenEx (Python).
The following open options are supported:
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-104 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)
