Spatiotemporal Changes in 3D Building Density with LiDAR and GEOBIA: A City-Level Analysis

Karolina Zięba-Kulawik, Konrad Skoczylas, Ahmed Mustafa, Piotr Wężyk, Philippe Gerber, Jacques Teller, Hichem Omrani
2020 Remote Sensing  
For this purpose, we use airborne laser scanning (ALS) point cloud (2019) and geographic object-based image analysis (GEOBIA) of aerial orthophotos (2001, 2010) to extract 3D models, footprints of buildings  ...  This paper explores urban volumetry using the Building 3D Density Index (B3DI) in 2001, 2010, 2019, and quantifies changes in the volume of buildings and urban expansion in Luxembourg City over the last  ...  Due to the increasingly widespread use of LiDAR technologies, point clouds present valuable spatial information about buildings in a clear and synthetic way, thus being a tool for extracting 3D features  ...

3D Façade Labeling over Complex Scenarios: A Case Study Using Convolutional Neural Network and Structure-From-Motion

Rodolfo Lotte, Norbert Haala, Mateusz Karpina, Luiz Aragão, Yosio Shimabukuro
2018 Remote Sensing  
However, newer neural network architectures have brought back the interest in their application for autonomous classifiers, especially for image classification purposes.  ...  Urban environments are regions in which spectral variability and spatial variability are extremely high, with a huge range of shapes and sizes, and they also demand high resolution images for applications  ...  Very sparse point clouds can generalize feature volumetry too much, while very dense point clouds can represent it faithfully, and the associated computational cost will also increase.  ...
