ST-Visions

ST-Visions

Highlights
A Python-based library for interactive spatio-temporal data visualization. Overview ST_Visions (Spatio-Temporal Visualizations) is a python library, able to interactively visualize spatio-temporal data in a quick-and-easy way. Based upon the functionality of Bokeh, and further extending it, we are able to create powerful and cohesive visualizations (and/or online dashboards), for large or streaming spatio-temporal datasets.

Hermoupolis – A Trajectory Generator for Simulating Generalized Mobility Patterns

Hermoupolis – A Trajectory Generator for Simulating Generalized Mobility Patterns

Highlights
During the last decade, the domain of mobility data mining has emerged providing many effective methods for the discovery of intuitive patterns representing collective behavior of trajectories of moving objects. Although a few real-world trajectory datasets have been made available recently, these are not sufficient for experimentally evaluating the various proposals, therefore, researchers betake to…

Hermes Moving Object Database

Hermes Moving Object Database

Highlights
Moving Object Database (MOD) engines enable us to process, manage and analyze mobility data. Hermes provides MOD functionality to OpenGIS-compatible state-of-the-art Object-Relational DBMS. In general, the big picture of Hermes aiming for the efficient management and exploration of mobility data is illustrated in the following figure.
