Singapore: The Singapore Land Authority (SLA) is leading a nation-level initiative to develop and maintain a 3D National Topographic Model to facilitate the efficient exchange and use of topographic information among agencies. “Today, topographic plans are produced and kept by separate agencies to serve localised development needs (e.g. for a particular development area). Given the increasing need for accurate 3D information on the as-built environment, there is a need for SLA to take the lead to capture and produce much-needed 3D data for Agencies’ critical needs such as flood risk modeling, flight path planning, environment and coastal protection, and many more,” says Ng Siau Yong, Director of the Geospatial Division at SLA.
SLA will be creating a 3D topographic database allowing efficient maintenance so as to keep the 3D data constantly up-to-date. “This entire process will be challenging, since it is akin to surveying the whole Singapore in one instance and producing accurate 3D mapping data from it,” added Siau.
