Impact of levels of detail (LOD) in the digital model on solar resource estimation

Year: 2025

Type: conference-paper

Abstract: Urban digital modelling is a complex process that involvesheterogeneous data sources (point clouds, site plans, GIS data),facilitating their integration and ensuring consistency. Digital modelsstandardised according to the CityGML specification are created atvarious levels of detail (LOD), which define the data required for themodelling of these digital representations.The aim of this article is to examine the relevance of usingdifferent levels of detail in modelling for solar potential estimation,using the CitySIM software. The study demonstrates that these levelsof detail have a significant impact on the accuracy of the solarpotential of digital models, although the extent of this impact variesdepending on the data progressively integrated during the modellingprocess.
