Abstract. Understanding urban vertical structures, particularly building heights, is essential for examining the intricate interaction between humans and their environment. Such datasets are indispensable a variety of applications, including climate modeling, energy consumption analysis, socioeconomic activities. Despite importance this information, previous studies have primarily focused on estimating heights regionally at grid scale, often resulting in with limited coverage or spatial resolution. This limitation hampers comprehensive global analysis ability to generate actionable insights finer scales. In study, we developed height map footprint scale by leveraging Earth Observation (EO) advanced machine learning techniques. Our approach integrated multisource remote-sensing features morphology develop estimation models using extreme gradient boosting (XGBoost) regression method across diverse regions. methodology allowed us estimate individual buildings worldwide, culminating creation three-dimensional (3D) Global Building Footprints (3D-GloBFP) dataset year 2020. evaluation results show that perform exceptionally well R2 values ranging from 0.66 0.96 root-mean-square errors (RMSEs) 1.9 14.6 m 33 subregions.

The comprehensive characterization of global urbanization requires consideration both human activities and urban physical structures. Both structures exhibit regular self-similar patterns, yet the spatial patterns between two at a scale remain elusive. This study utilized NPP-VIIRS annual composite data newly available world settlement footprint 3D to investigate relationships nighttime light intensity building morphological indicators across several scales. Our results demonstrated that there is weak association morphology pixel level, as shown by maximum correlation coefficient approximately 0.4, but strong provincial/state level with over 0.8. Additionally, we performed an urban-rural gradient analysis evaluate indicators. indicated dominant gradients for morphologies follow declining trend from centers rural areas. Notably, inconsistencies were found predominantly in Africa. findings also suggested can be served indicator urbanization, thus provide implications facilitating solutions aimed reducing income disparity promoting sustainable development.

Building height serves as an essential feature of urban morphology that provides valuable insights into human socio-cultural behaviors and their impact on the environment in milieu. However, openly accessible building information at individual level is still lacking remains sorely limited. Previous studies have shown ICESat-2′s ATL03/08 products are good accuracy for heights retrieval, however, these limited to areas with available data coverage. To this end, we propose a method extracting by using ICESat-2 ATL03 photons high-resolution remote sensing images. We first extracted roof footprint offsets shadows from high resolution imagery multitasking CNN frameworks. Using samples calculated photons, developed estimation combines offset shadow length information. assessed efficacy proposed Wujiaochang area Shanghai city, China. The results indicated able extract MAE 4.7 m, outperforms traditional shadow-based offset-based method. believe candidate accurately retrieving city-wide scale.
