Spatial analysis for extremely large astronomical catalogs using dask

LSDB

LSDB

LSDB is a python tool for scalable analysis of large catalogs (i.e. querying and crossmatching ~10⁹ sources). This package uses dask to parallelize operations across multiple HATS partitioned surveys.

Check out our ReadTheDocs site for more information on partitioning, installation, and contributing.
