Abstract Urbanisation is transitioning from disorderly sprawl to compact intensification, accompanied by functional differentiation and morphological changes spatially. This study addresses the relationship between urban functions morphologies at block scale in Hangzhou. Leveraging geo‐big data, we adopt a points of interest (POI) weighting method map four essential functions—residential, commercial, public service, industrial—at traffic analysis zones (TAZ) scale. Additionally, estimate indices using building footprint data volume data. Our investigation reveals intriguing patterns: residential, service exhibit central concentration trend diminishing towards periphery, whereas industrial demonstrate multi‐hotspot distribution. Morphological like patch density mean while size shape index, presenting pronounced peripheral distribution trend. Significantly, nuanced associations were elucidated. Residential tend display dense small patches, commercial areas showcase larger volumes, complex shapes. Furthermore, construction intensity‐based heterogeneity unveils dynamics morphologies, particularly high‐density areas. These findings underscore importance integrating considerations into planning, offering fresh perspective for zoning planning.

The intertidal ecosystem serves as a critical transitional zone between terrestrial and marine environments, supporting diverse biodiversity essential ecological functions. However, these systems are increasingly threatened by climate change, rising sea levels, anthropogenic impacts. Accurately mapping ecosystems differentiating mangroves, salt marshes, tidal flats remains challenge due to inconsistencies in classification frameworks. Here, we present high-precision approach for using multi-source satellite data, including Sentinel-1, Sentinel-2, Landsat 8/9, integrated with the Google Earth Engine (GEE) platform, enable detailed of zones across China–ASEAN. Our findings indicate total area 73,461 km2 China–ASEAN, an average width 1.16 km. Analyses patch area, abundance, perimeter relationships reveal power-law distribution scaling exponent 1.52, suggesting self-organizing characteristics shaped both natural human pressures. offer foundational data guide conservation management strategies region’s novel perspective propel research on global coastal ecosystems.

Urbanization have been significantly reshaping the form of urban areas and natural landscapes, leading to complex morphologies. In 2012, Local Climate Zone (LCZ) classification was proposed address this issue has since widely adopted in climate studies globally. Despite its prevalence, literature on dynamic mapping morphology remains sparse, making it difficult delve into study renewal year by year. study, we compared different training scales, producing mappings with a spatial resolution 100 meters spanning from 2000 2022 major Chinese cities, based LCZ scheme. The results demonstrate strong inter-year consistency, accuracy change is overall higher than 70%. Additionally, our exhibit good alignment other datasets, more suitable for current development situation China, effectively discriminate between building heights densities across types. This dataset holds significant potential enhancing monitoring advancing research.

Rapidly acquiring three-dimensional (3D) building data, including geometric attributes like rooftop, height and orientations, as well indicative function, quality, age, is essential for accurate urban analysis, simulations, policy updates. Current datasets suffer from incomplete coverage of multi-attributes. This paper presents the first national-scale Multi-Attribute Building dataset (CMAB) with artificial intelligence, covering 3,667 spatial cities, 31 million buildings, 23.6 billion m² rooftops an F1-Score 89.93% in OCRNet-based extraction, totaling 363 m³ stock. We trained bootstrap aggregated XGBoost models city administrative classifications, incorporating morphology, location, function features. Using multi-source billions remote sensing images 60 street view (SVIs), we generated height, structure, style, quality each machine learning large multimodal models. Accuracy was validated through model benchmarks, existing similar products, manual SVI validation, mostly above 80%. Our results are crucial global SDGs planning.
