3D / 4D VISUALIZATION CESIUMJS MASTER'S PROJECT

Reliving Nevado del Ruiz

3D/4D Geovisor · Manizales, Colombia

An interactive visualization of the geography, volcanic risk, and historical memory of the region. Explore the terrain, activate geoscientific layers, and simulate eruptive scenarios in a 4D timeline.

Eruptive scenario

Educational visualization of a hypothetical lahar, inspired by the November 13, 1985 event (Nevado del Ruiz · VEI 3 · Armero Tragedy). It is not an exact reconstruction of that lahar.

Elapsed time 00:00

Distance covered 0.00 km

Local velocity 0 km/h

Model: v = clamp(5 + 40·tan(α), 5, 18) m/s, where α is local downhill slope. Calibrated with Armero lahar data (1985).

About the project

This geovisor demonstrates the use of CesiumJS as an open-source tool for SIG/GIS professionals to publish their results in a 3D, interactive, and geodesically correct (WGS84 globe) manner on the web — without expensive proprietary software.
