The generated data can directly be used in existing noise simulation software. buildings, terrain, land coverage, bridges and noise barriers) from current 2D topographic data and point clouds. ![]() To address this problem, this paper presents a methodology to automatically generate 3D input data as required in noise simulations (i.e. This is not efficient, but also differences in input data may lead to differences in the results of noise simulation which has a negative impact on the reliability of noise studies. Currently, different organisations collect their own 3D input data as required in noise simulation in a semi-automated way, even if areas overlap. The simulation of noise is an important part of these studies. To monitor and manage noise problems, governmental organisations at all levels are obliged to regularly carry out noise studies. ![]() Noise is one of the main problems in urban areas.
