Assessing OSM building completeness for almost 13,000 cities globally

International Journal of Digital Earth, 2022
OpenStreetMap (OSM) is an essential source for acquiring building data, although such data may suffer from quality issues. Many studies have focused on assessing OSM building data quality but few have been carried out on a global scale.

Protein Profiling Reveals Novel Proteins in Pollen and Pistil of W22 (ga1; Ga1) in Maize

, 2014
Gametophytic factors mediate pollen-pistil interactions in maize (Zea mays L.) and play active roles in limiting gene flow among maize populations and between maize and teosinte.

A new extraction and grading method for underwater topographic photons of photon-counting LiDAR with different observation conditions

International Journal of Digital Earth
Spaceborne photon-counting light detection and ranging (LiDAR) have been extensively applied in shallow-water bathymetry. The density of underwater topographic photons (UTP) varies and is discontinuous due to sunlight noise, beam intensity, and seabed ...

Identifying urban functional zones by capturing multi-spatial distribution patterns of points of interest

International Journal of Digital Earth, 2022
Urban Functional Zone (UFZ) identification is vital for urban planning, renewal, and development. Point of Interest (POI), as one of the most popular data in UFZ studies, is transformed into a geo-corpus under specific sampling strategies, which can be ...
