  1. UPRM-TVE: Terrain Visualization Explorer Understanding the dynamics of the hydrological phenomena associated to wetlands requires analyzing models built upon remotely gathered data, such as satellite images or digital elevation maps (DEM). The UPRM-TVE aims to provide framework which will allow building more powerful visualization tools to complement the analysis of hydrological models for the study of wetlands.

  2. Project Goals Provide a synoptic view of the spatial-temporal distribution and dynamics of hydrological phenomena using visualization techniques and integrating: • Database of digital elevation maps and satellite images • Sensor arrays • Hydro-ecological models

  3. Project Status • Prototype implemented using Java and OpenGL for cross-platform deployment with hardware accelerated rendering. • Using DEM and satellite imagery of the Jobos Bay Reserve, we will explore different aspect related to: • Performance scalability of terrain visualization. • Scientific visualization of spatial-temporal data. • Integration of diverse data acquired through remote sensing. • Integration between hydrological modeling and visualization.
