Overview

Current research projects are mainly the result of my educational activity at ITC (MSc supervision) and cooperation with other department members. My interest in the last years has shifted from the extraction of image features to the representation of those (extracted) trajectories. More precisely my interest is moving around: system design for web visualization of (large) trajectory data.

Trajectory data

There is a set of (water-related) trajectories that we are experimenting with: icebergs trajectories collected by Brigham Young University from 1978 till present time.

System design

We are currently working on three layered system architecture that consists of:

  • Spatial data base management system (Postgres/PostGIS) to manipulate the trajectories.
  • Visualization layer that communicates with the database. Mainly we are looking at various (free and open source) JavaScript libraries.
  • Additional layer that interacts with various image servers to extract additional information and to store it in the database. For instance, to understand the iceberg evolution, we have to take into account sea surface temperature, air temperature, wind speed, wind direction etc...

Visualization

Hopefully soon you will be able to see results. Probably something like this...
