Modeling and Querying Trajectories using Neo4j Spatial and TimeTree for Carpool Matching

by

Abstract—With the the exponential growth of location aware devices, analysis of human movements has been the subject of several studies. Problems related to urban mobility such as vehicle congestion are serious concern in cities. Carpooling is one of the solutions to soften congestion problem. This paper presents a novel matching method for carpooling. Trajectories are … Read more

MapReduce Based Scalable Range Query Architecture for Big Spatial Data

by

Abstract-Finding all objects that overlap a given range query is very important in terms of extraction useful information from big spatial data. In this study, in order to be able to realize range query on large amounts of spatial data, three datasets are created with different size and a MapReduce computation model is set up … Read more

Visual Analysis Of Time and Location Dependent Data On the Maps

by

Advances in satellite end map technology have provided various opportunities such as analysis and interpretation of time and location dependent data. In this study, graphical tools enabling analysis and visualization of this kind of data (temperature values in the last five years for Turkey) on the map have been plotted via texture mapping technique.   … Read more
