The prototype of a geo-data sharing network for the Asia Pacific is expected to be completed by September this year. Coordinated by the Thai space technology and geo-informatics organisation GISTDA, the ASEAN +3 Satellite Image Archive for Environmental Study project is designed to aid scientists and governments to tackle disaster and environmental problems in the region.

Geo-spatial information can help in the management of disasters.

ASIA-ES aims to make it easier to share satellite image archives between the ASEAN+3 member countries through an internet-based distribution network.

The data clearinghouse will house Earth observation satellite data and other environment-related information gathered by space agencies in the region.

GISTDA is currently setting up a central network through which participating agencies will each maintain and update their own databases and catalogues.

These catalogues will be accessed through a catalogue browsing system. Governments, public organisations and eventually, some private sector firms will also have access to this information.

In the ASEAN+3 community, satellite imagery is usually acquired, archived and maintained separately by space agencies in countries with ground receiving stations. Incorporating existing information into a region-wide database will enable researchers and governments to better understand and manage of problems such as deforestation, pollution, poor water quality, flooding, prolonged dry seasons and declining public health.

The application will also assist regional governments in coordinating more timely and effective responses to environmental crises occuring either across the region or in other countries.

The web portal will combine an Intergraph 2D web GIS with Skyline 3D visualisation software. Permitted users will be able to access, download and upload metadata of images.

MapPointAsia Thailand, a local company working with Perth-based McMullen Nolan and Partners Surveyors to distribute Skyline, will develop this web portal.

‘In the first phase, we implemented clearinghouse and webmap services to support disaster event data.

‘In this current, second phase, we are adding a Skyline spatial simulation system and catalogue functions.

‘The final phase will expanding the system to support more users and services,’ said Pisit Manopinives, a spokesperson for MapPointAsia.

The dissemination of 3D information online will involve the integration of three Skyline components: TerraBuilder, for the fusion of imagery and elevation data, TerraExplorerPro, for the customisation of the 3D base file with GIS and other data such as live sensor feeds, and TerraGate, Skyline’s internet streaming component.

GISTDA anticipates cooperation will go beyond the sharing of satellite image archives. Remote sensing and GIS experience, applications, tools, and technical knowledge from remote sensing and computer experts will also be exchanged through the portal.

The ASEAN+3 member countries are Brunei, Cambodia, Indonesia, Laos, Malaysia, Burma, Philippines, Singapore, Thailand, Vietnam, China, Japan, and South Korea.

ASM Newsletter is distributed by e-mail every week. It reports on events in the spatial industry in Asia and events outside the region which will impact on Asia.
