The eo-tides package provides powerful parallelized tools for integrating satellite Earth observation (EO) data with ocean tide modelling. The package provides a flexible Python-based toolkit for modelling and attributing tide heights to a time-series of satellite images based on the spatial extent and acquisition time of each satellite observation.

eo-tides leverages advanced tide modelling functionality from the pyTMD tide prediction software, combining this fundamental tide modelling capability with EO spatial analysis tools from odc-geo. This allows tides to be modelled in parallel automatically using over 50 supported tide models, and returned in standardised pandas and xarray data formats for further analysis.

Tools from eo-tides are designed to be applied directly to petabytes of freely available satellite data loaded from the cloud using Open Data Cube's odc-stac or datacube packages (e.g. using Digital Earth Australia or Microsoft Planetary Computer's SpatioTemporal Asset Catalogues). Additional functionality enables evaluating potential satellite-tide biases, and validating modelled tides using external tide gauge data — both important considerations for assessing the reliability and accuracy of coastal EO workflows. In combination, these open source tools support the efficient, scalable and robust analysis of coastal EO data for any time period or location globally.
