Three-dimensional modeling: street environment

Seeking new ways to produce a 3D surface models of the street environment.

In a pilot conducted by Sitowise, the goal was to produce a 3D model of the urban environment, which can be utilized in examining various modes of transportation environments in Helsinki. The method used in the pilot was a continuation of Sitowise’s work created in the spring of 2022, where a tool was developed using the FME conversion process to transform road features from the General Area Registry (YLRE) into CityGML format. 

Zero Gravity was developing a way to combine existing City of Helsinki data on traffic areas with manual labelling for the training dataset as well as creating a segmentation model to extend to the rest of pilot area.
