A Distributed Map Animation Framework for Spatiotemporal Datasets

Maps are an excellent way to present data that have spatial components. However, when the data being presented vary over time, a simple two-dimensional map ignores an important feature of the data. An animated map that shows a series of two-dimensional maps at successive points in time allows one to add a time dimension to … Read more A Distributed Map Animation Framework for Spatiotemporal Datasets

Evaluation of Different Algorithms for Measuring the Similarities of Trajectory Datasets

Abstract—With the techologicaltechnological development of global positioning system and video survelliancesurveillance systems and extensive utilization of socailsocial media platforms, large amounts of trajectories data are captured. Processing and analysinganalyzing of moving obgectsobjects such as people, animals, and vehicles provides valuable information for industrial and academic studies. about them. In this study, three different similarity algorithms … Read more Evaluation of Different Algorithms for Measuring the Similarities of Trajectory Datasets

MapReduce Based Scalable Range Query Architecture for Big Spatial Data

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 MapReduce Based Scalable Range Query Architecture for Big Spatial Data

Visual Analysis Of Time and Location Dependent Data On the Maps

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 Visual Analysis Of Time and Location Dependent Data On the Maps
