STMTools

STMTools (Space-Time Matrix Tools) is an Xarray extension for Space-Time Matrix operations (Bruna et al., 2021; van Leijen et al., 2021). It provides tools to read, write, enrich and manipulate a Space-Time Matrix (STM).

An STM is a dataset containing data with a space (point, location) and time (epoch) component, as well as contextual data. STMTools utilizes Xarray’s multi-dimensional labeling feature, and Zarr's chunk storage feature, to efficiently read and write large Space-Time matrices.

The contextual data enrichment functionality is implemented with Dask. Therefore it can be performed in a paralleled style on High Performance Computing (HPC) systems.

At this stage, STMTools specifically focuses on the implementation for radar interferometry measurements, e.g. Point Scatterers, Distributed Scatterers, etc, with the possibility to be extended to other measurements with space and time attributes.
