Continuous Monitoring of Nearest Neighbors on Land Surface

Summary: Presents two exact, dynamic skNN methods for moving objects on land surfaces, enabling GIS/LBS monitoring. SE-Tree is fat/short; ASI-Tree, a balanced angular-index tree with precomputed surface distances, localizes searches and speeds shortest-paths, beating SE-Tree.
