Increasing urbanisation, pressure on existing infrastructure, push for productivity in construction sector and environmental concerns are driving the convergence of geospatial, 3D and information modeling technologies.
Over the next two decades, construction of buildings and infrastructure (electric power, water/wastewater, roads and highways, and ports and airports) will see a massive infusion of investment, motivated by environmental concerns and the need to accelerate economic development. As governments are discovering that they have less and less money for capital infrastructure projects, a greater proportion of the investment in infrastructure will come from the private sector, which will drive increasing productivity to improve returns on investment. As with other industries facing a productivity challenge, this translates into an investment in technology. The accelerating adoption of 3D technologies includes 3D visualisation, 3D building information modelling (BIM), 3D GIS, 3D CAD, 3D reality capture such as laser scanning (LiDAR) and ground penetrating radar (GPR), 3D photogrammetry from satellites, aircraft and UAVs, and technologies that enable 3D measurement such as oblique imagery is transforming the construction industry in important areas.
In a just published article in Geospatial World I discuss how 3D data and technologies integrated with geospatial and other technologies are being applied to model buildings, infrastructure, and entire urban environments ranging from individual buildings to neighbourhoods to cities, how this is feasible using today’s technology, and how it is already transforming the construction industry.
