track_code

From 4.2.1.1.10.2, The optional attribute trackCode has the value type CharacterString which may contain a text string describing the reason for the override of the corresponding depth and uncertainty values in the bathymetry coverage. This is a user definable field with values defined in the lineage metadata.

Return type

str

track_code_type
value

The attribute value has the value class Record which is a sequence of value items that shall assign values to the discrete grid point. There are two values in each record in the S102_TrackingListValues class. These are the depth and the uncertainty values that were overridden in corresponding grid coverages

‘value’ in tracking list should be HDF5 dataset of (depth, uncertainty) which are matched to the listSeries which holds the indices of the data locations

It is an ISO 19103 class Record

Return type

Union[ndarray, Dataset]

Methods Documentation

add_data(key, value)
geometry_create()
get_all_keys()

Gets all the non-standard keys that are contained in this object currently as well as all the standard keys (S100/HDF5 style names) that could be added.

Return type

list

get_compound_dtype()

Override this method if the dtype of compound dataset items is important

Return type

A list of dtype, None otherwise.

get_data(key)
get_hdf5_from_file(file_obj)
get_s1xx_attr(s1xx_name)
get_standard_keys()

Returns the S100 (HDF5) names for the things that are listed in the specs for this class.

Returns

The S102 HDF5 group/attribute/dataset names from this object that will be written or read from an HDF5 file. e.g. BathymetryCoverage or westBoundLongitude etc.

For the class “Root”: [‘BathymetryCoverage’, ‘Group_F’, ‘TrackingListCoverage’]

Return type

list

get_standard_list_properties()

Returns a list of properties that are lists (children based on S1xxMetadataListBase). Basically a way of finding which items will be named <name>_001, <name>_002 etc

Returns

The property names that will have auto-generated names based on their index in a list.

Return type

list

classmethod get_standard_properties()

This function autodetermines the properties implemented (which have get/set @properties and _attribute_name associated)

Returns

Names of the properties implemented.

For eample class “Root” might have (for S102): [‘bathymetry_coverage’, ‘feature_information’, ‘tracking_list_coverage’]

Return type

list

get_standard_properties_mapping()

This function autodetermines the HDF5 or xml names and their associated property names. Keys are the s100 (HDF5 spelling) strings and the values are the python style naming.

Returns

dictionary of xml element names as keys and property names as values.

For the class “Root”: {‘BathymetryCoverage’: ‘bathymetry_coverage’, ‘Group_F’: ‘feature_information’, ‘TrackingListCoverage’: ‘tracking_list_coverage’}

Return type

dict

get_write_order()

Override this method if the write order of attributes/groups/dataset items is important

Return type

A list of key names if order is important, None otherwise.

initialize_properties(recursively_create_children=False, overwrite=True)

Calls the create function for all the properties of the class. Default values will be created for each attribute that is expected to be contained in this object.

For example, say a class has simple attributes of ESPG code (int) and locatilty (str) and then a class made from S1xxAttributesBase called “extents” which has east and west inside it.

Calling initialize_properties(recursively_create_children=False) would result in EPSG=0, locality=”” and an instance of the “extents” class but NO value (nothing would be written to HDF5) for east, west.

Calling initialize_properties(recursively_create_children=True) would result in EPSG=0, locality=”” and an instance of the “extents” class but with east=0.0 and wesst=0.0 as well.

Calling initialize_properties(recursively_create_children=True, overwrite=False) with an esiting dataset, say locality=”test” would result in EPSG=0 being made, locality=”test” being retained and an instance of the “extents” class with east=0.0 and wesst=0.0 as well.

Parameters
  • recursively_create_children – True = Create children for any child data that would have other children False = Only create data for immediate children of this instance

  • overwrite – True = Overwrite existing data with new default data False = Keep existing data if it exists but create new data otherwise

Return type

None

list_series_create()
read(group_object)

Given an h5py.File or a h5py group then read the data based on the encoded S100+ spec.

Parameters

Return type

None

read_simple_attributes(group_object)

Reads the standard simple types (strings, ints, floats, datetimes, enums) from the given group as specified by the class specs.

Parameters

group_object – The group (an h5py.File is a group too) to read from.

Return type

None

set_datetime_attribute(val, attribute_name, date_type)

A DateTime is a combination of a date and a time type. Character encoding of a DateTime must follow ISO 8601:2004 ( :2004 took away partial dates with two digit year or just month/day) EXAMPLES 19850412T101530 2001-07-17T04:50:00 2012-11-01T00:44:00+10:30 2001-07-17 19850412T101530.44 19850412T101530.44Z 19850412T101530.44+10 19850412T101530.44+1030 19850412T10:15:30Z
