Indexicon: A Spatial Indexing Library
Panagiotis Simatis, Panagiotis Bouros, Nikos Mamoulis
Spatial indexing is foundational to Geographic Information Systems (GIS) and multi-dimensional data management, yet the current open-source landscape poses a significant barrier to…
Two-layer Space-oriented Partitioning for Non-point Data
Dimitrios Tsitsigkos, Panagiotis Bouros, Konstantinos Lampropoulos +2
Non-point spatial objects (e.g., polygons, linestrings, etc.) are ubiquitous. We study the problem of indexing non-point objects in memory for range queries and spatial intersectio…
HINT: A Hierarchical Index for Intervals in Main Memory
George Christodoulou, Panagiotis Bouros, Nikos Mamoulis
Indexing intervals is a fundamental problem, finding a wide range of applications. Recent work on managing large collections of intervals in main memory focused on overlap joins an…
A Two-level Spatial In-Memory Index
Dimitrios Tsitsigkos, Konstantinos Lampropoulos, Panagiotis Bouros +2
Very large volumes of spatial data increasingly become available and demand effective management. While there has been decades of research on spatial data management, few works con…
Parallel In-Memory Evaluation of Spatial Joins
Dimitrios Tsitsigkos, Panagiotis Bouros, Nikos Mamoulis +1
The spatial join is a popular operation in spatial database systems and its evaluation is a well-studied problem. As main memories become bigger and faster and commodity hardware s…
Finding k-Dissimilar Paths with Minimum Collective Length
Theodoros Chondrogiannis, Panagiotis Bouros, Johann Gamper +2
Shortest path computation is a fundamental problem in road networks. However, in many real-world scenarios, determining solely the shortest path is not enough. In this paper, we st…
Set Containment Join Revisited
Panagiotis Bouros, Nikos Mamoulis, Shen Ge +1
Given two collections of set objects and , the set containment join returns all object pairs such that . Bes…
Routing Directions: Keeping it Fast and Simple
Dimitris Sacharidis, Panagiotis Bouros
The problem of providing meaningful routing directions over road networks is of great importance. In many real-life cases, the fastest route may not be the ideal choice for providi…
