API and Utilities for Working with IHO S-100 HDF5 Data Formats
Overview
--------
This python package includes an API and utilities for encoding hydrographic
datasets in the International Hydrographic Organization (IHO) S-100
HDF5 format.
See [s100py Read the Docs](https://s100py.readthedocs.io/en/latest/) for more information.
Background
----------
The IHO S-100 standard is a data framework for digital products and
services for hydrographic, maritime, and GIS communities, comprised of
multiple data encoding formats designed for interoperability with
Electronic Navigational Charts (ENCs).
This package includes the following S-100 encoding formats:
- S-102 Bathymetric Surface
- S-104 Water Level Information for Surface Navigation
- S-111 Water Currents for Surface Navigation
However, support for additional formats as they become available will
be added in the future. For further information about S-100 formats,
see the [IHO website](http://s100.iho.int/S100/).

Requirements
------------
This codebase is written for Python >=3.8 and relies on the following python
packages:
- h5py
- numpy
- gdal
Installation
------------
Conda
-----
Installing s100py from the conda-forge channel can be achieved by adding conda-forge to your channels with:
```bash
conda config --add channels conda-forge
conda config --set channel_priority strict
```
Once the conda-forge channel has been enabled, s100py can be installed with conda:
```bash
conda install s100py
```
or with mamba:
```bash
mamba install s100py
```
It is possible to list all the versions of s100py available on your platform with conda:
```bash
conda search s100py --channel conda-forge
```
or with mamba:
```bash
mamba search s100py --channel conda-forge
```
Alternatively, mamba repoquery may provide more information:
**Search all versions available on your platform:**
```bash
mamba repoquery search s100py --channel conda-forge
```
**List packages depending on `s100py`:**
```bash
mamba repoquery whoneeds s100py --channel conda-forge
```
**List dependencies of `s100py`:**
```bash
mamba repoquery depends s100py --channel conda-forge
```
PIP
---
If installing with PIP, this package requires GDAL Python bindings be present,
so it usually can't be installed just using `pip install gdal`, but for more information
visit https://pypi.org/project/GDAL/.
Once `gdal` has been installed, s100py can be installed using `pip`:
```bash
pip install s100py
```

**Version 1.0.0-rc.1 (2021-02-11)**
- This is a major release, which includes a new API that encapsulates the data specifications to allow
introspection with Python to determine what data is available or should be and what data types would
be acceptable. Convenience utilities are available to convert data into S102/S104/S111 so detailed
knowledge of the S100 specs and APIs is not required in most cases
- Support for s102 (bathymetry) and s104 (water levels) has been added
- A consistent API for S100 data structures was added and is used to encode S102, S104, and S111
- The previous S111 library has been migrated to this general S100 API and therefore any
code written against the previous s100py library will no longer work
- Examples of using the new S111 API are available [here](https://s100py.readthedocs.io/en/latest/s111.html#example-usage)

the best estimate of the\n variable horizontal or vertically accuracy component for positions, depths, heights, vertical distances, and\n vertical clearances\n * The start date of the period of the hydrographic survey\n * The end date of the period of the hydrographic survey\n * The survey filename or ID\n * The authority which as responsible for the hydrographic survey\n * An estimate of the magnitude of the difference between true and estimated bathymetric depth, after all appropriate\n corrections are made\n- S-111 Edition 1.2.0 (S-100 Edition 5.0.0) significant changes include:\n * General metadata _horizontalDatumReference_ and _horizontalDatumValue_ have been removed\n * General metadata attributes _horizontalCRS_ and _typeOfHorizontalCRS_ were added\n * Stricter datatypes have been set for all attributes\n * General metadata attribute _depthTypeIndex_ has been modified to only allow _heightOrDepth_ or _layerAverage_\n * General metadata _datasetDeliveryInterval_ was added, describing the expected time interval between availability of\n successive datasets for time-varying data, formatted as an ISO 8601 duration (e.g. 'PnYnMnDTnHnMnS')\n * The enumeration attribute for the classification of data according the relationship between the time of its collection,\n generation or calculation of generation parameters, in relation the time of publication has been changed from\n _typeOfCurrentData_ to _dataDynamicity_\n- S-104 Edition 1.1.0 (S-100 Edition 5.0.0) significant changes include:\n * General metadata _horizontalDatumReference_ and _horizontalDatumValue_ have been removed\n * General metadata attributes _horizontalCRS_ and _typeOfHorizontalCRS_ were added\n * Stricter datatypes have been set for all attributes\n * General metadata _datasetDeliveryInterval_ was added, describing the expected time interval between availability of\n successive datasets for time-varying data, formatted as an ISO 8601 duration (e.g. 'PnYnMnDTnHnMnS')\n * The enumeration attribute for the classification of data according the relationship between the time of its collection,\n generation or calculation of generation parameters, in relation the time of publication has been changed from\n _typeOfWaterLevelData_ to _dataDynamicity_\n * General metadata _trendInterval_ was added, describing the interval in minutes over which trend at a particular time\n is calculated\n\n**Version 1.0.0-rc.1 (2021-02-11)**\n- This is a major release, which includes a new API that encapsulates the data specifications to allow\n introspection with Python to determine what data is available or should be and what data types would\n be acceptable. Convenience utilities are available to convert data into S102/S104/S111 so detailed\n knowledge of the S100 specs and APIs is not required in most cases\n- Support for s102 (bathymetry) and s104 (water levels) has been added\n- A consistent API for S100 data structures was added and is used to encode S102, S104, and S111\n- The previous S111 library has been migrated to this general S100 API and therefore any\n code written against the previous s100py library will no longer work\n- Examples of using the new S111 API are available [here](https://s100py.readthedocs.io/en/latest/s111.html#example-usage)\n\nAuthors\n-------\n\n- Barry Gallagher (NOAA), <barry.gallagher@noaa.gov>\n- Erin Nagel (UCAR), <erin.nagel@noaa.gov>\n- Glen Rice (NOAA), <glen.rice@noaa.gov>\n- Jason Greenlaw\n\n\nLicense\n-------\n\nThis work, as a whole, falls under Creative Commons Zero (see\n[LICENSE](LICENSE)).\n\nDisclaimer\n----------\n\nThis repository is a scientific product and is not official\ncommunication of the National Oceanic and Atmospheric Administration, or\nthe United States Department of Commerce.
