K Nearest neighbor join algorithms for spatial data using compact and plain data structures in main memory

The K Nearest Neighbors Query (KNNQ) is a fundamental distance-based query with applications in Geographic Information Systems (GIS) and many other domains. The K Nearest Neighbors Join Query (KNNJQ) combines KNNQ with the join operation to find the K nearest neighbors from a dataset P to every object in another datase...
