The Land Survey Division within the Singapore Land Authority (SLA) develops mapping and positioning data and administers the cadastre and mapping framework for Singapore. The purpose of mapping is to capture landscapes and streetscapes, digitize these data and make them available for other uses.
In its first phase of mapping, an airborne laser scanning and imaging equipment was flown over Singapore to collect 3D point cloud and imagery data of the whole nation.
Phase two of the national 3D mapping project involved a comprehensive mobile mapping project that was carried out to collect a ground-based laser scanning and 360 panoramic imagery dataset on approximately 6,000 km of roads. The data collected was used to create 3D models of road and street furniture.
These data sets would be used to create the first nation-wide 3D maps of Singapore which will contribute to the development of a Smart Nation. The 3D digital models are taken into Virtual Singapore to be used by the public, private and people (3P) and research sectors.
As SLA continues to improve its mapping capabilities, SLA is exploring mesh modelling, which can process up to half a million images and produce a very detailed national model within 2 to 3 months. Senior Deputy Director/Land Survey Division, Dr Victor Khoo said, “What we plan to do or achieve is definitely not done overnight. However, SLA is on the right track and we will continuously build up our capacity to map for the City of the Future.”
