SIMPLIFIED 3D CITY MODELS FROM LIDAR [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2012
Aerial laser scan data is widely used to produce 2 1/2D digital elevation models automatically. However, creating full 3D city models from this data is a complex task.

On the Reliable Generation of 3D City Models from Open Data

open access: yesUrban Science, 2020
A 3D model communicates more effectively than a 2D model, hence the applications of 3D city models are rapidly gaining significance in urban studies. However, presently, there is a dearth of free of cost, high-resolution 3D city models available for use.

Versioning of 3D City Models for Municipality Applications: Needs, Obstacles and Recommendations

open access: yesISPRS International Journal of Geo-Information, 2021
The use of 3D city models is changing from visualization to complex use cases where they act as 3D base maps. This requires links to registers and continuous updating of the city models. Still, most models never change or are recreated instead of updated.
