Airborne LiDAR

EOS has developed its capability of aerial acquisition of LiDAR data (Airborne- LiDAR). The CGO has carried out airborne-LiDAR surveys in Nepal and Myanmar. Compared to the Ground-LiDAR, the Airborne-LiDAR is suitable for large-area/regional high-resolution surveys. This technique provides real topography through ultra-high resolution, vegetation free images of an area as large as several square kilometers.

Geotouch

GeoTouch

GeoTouch is a multi-touch display and information portal developed by the Earth Observatory of Singapore. It is a useful tool to visualize GIS content on a large multi-touch screen. A natural multi-touch interface allows the user to pan, zoom and 3D rotate maps and layers on display using touch to examine geographic and geological information.

Ground-penetrating Radar (GPR)

(GPR) is a technique that uses high-frequency radio waves to image the subsurface of the Earth. This technique is often used by our scientists to study sediment deposits related to coastal hazards in Southeast Asia.

The usage of the ground penetrating radar (GPR) at EOS provides scientists the useful information about the material properties in the shallow depth of the earth. This technique has been widely used in many other research fields from decades.

Infrasound Monitoring System

The infrasound monitoring system employed by EOS was first used to monitor volcanic eruptions from Indonesia. This monitoring system detects low-frequency sound waves, and the data collected will provide information on the location and explosivity of the eruption, allowing our scientists to determine the impact of volcanic ash on air traffic in and around Singapore.

The data from the Infrasound monitoring network contributes to the Tsunami early warning system, as it can detect the sound wave from the tsunami source well before the tsunami waves arrive the coastline.

Lab Volcano Facilities

Lab Volcano Facilities

The purpose of the Lab Volcanoes is to understand the timing, rates and other details of the magma supply of different volcanoes, in order to improve forecasts of future eruptions. To this end, laboratory volcanoes display very diverse monitoring tools that provide a constant flow of data.

MIBB GPS Network

Myanmar-Bangladesh-Assam GPS Network

EOS' Myanmar-India-Bangladesh and Bhutan GPS Network comprises stations along North-South and East-West transects.

The North-South transect is intended to measure the convergence across the Himalayan front and the Shillong Plateau.

The East-West transects will reveal the nature of strain accumulation across both the fold and thrust belt of the Indo-Burman Range and northern Sagaing fault.

Seismic Network

The seismic networks, linked by a satellite-based communication system, monitor the tectonic motion in several earthquake hotspots within South and Southeast Asia, thus providing essential information for scientists to understand the earthquake potentials from these mega fault-systems on earth.

Small Unmanned Aerial Vehicle

Small Unmanned Aerial Vehicle

Small Unmanned Aerial Vehicle (UAV) surveys provide detailed information of temporal landscape changes, post disaster landscape, and potentially high-resolution digital terrain models acquired from aerial photos taken from the drone. Our scientists use a combination of techniques, including images taken from the UAV, to investigate faults and volcanic activities.

Terrestrial LiDAR

LIDAR

The Earth Observatory of Singapore acquired a LIDAR (Light Detection and Ranging) in 2010. It is a RIEGL VZ-400, with a range up to 600m at Laser class 1, a repeatability of 3mm, and a measurement rate up to 125 000 measurements per second.
