arctern
Arctern is an open-source spatial-temporal analytics framework designed for fast and scalable data processing. It provides a unified interface for data analytics and processing across platforms ranging from laptops to clusters and the cloud. Built on a GeoDataFrame and GeoSeries abstraction that follows GeoPandas conventions, Arctern enables scaling both up and out across different execution environments. The framework delivers rich and consistent spatial-temporal algorithms suitable for various stages of a data science pipeline, including trajectory processing, spatial clustering, regression, spatial-relation operations, and rendering. It currently includes an efficient multi-threaded GeoSeries implementation, with a distributed version based on Spark under development. Performance benchmarks show Arctern achieving up to 24x speedup over GeoPandas in multi-threaded execution and an average 7x improvement in single-thread execution. It also offers GPU-accelerated rendering and spatial-relation operations with
