DITA: A Distributed In-Memory Trajectory Analytics System
Summary: DITA is an in-memory distributed trajectory analytics system offering threshold-based and KNN similarity search and space-time range queries. It integrates Spark SQL/DataFrame, supports diverse similarity functions, and uses partitioning with global/local indexes plus a filter-verification framework for scalable search and join.
