Urban Center Database 2025 - Geography & Climate
收藏资源简介:
The GHS Urban Centre Database (GHS-UCDB) describes spatial entities called “Urban Centres” described through a set of multi-temporal thematic attributes from the GHSL data combined with other free and open data sets. The UCDB is a global dataset of over 10,000 urban centers developed by the European Commission, providing multi-temporal and multi-thematic information based on a globally harmonized methodology. It supports global monitoring of policy frameworks and provides data for urban studies. Resolution is 1km. This Layer covers the Geography and Climate thematic domains. Under these the GHS-UCDB groups a variety of families and indicators, further divided in specific attributes, multitemporal (1970-2070). Attributes include biome classification, ecoregions, soil class, climate indicators and climate zones.

The GHSL relies on the design and implementation of spatial data processing technologies that allow automatic data analytics and information extraction from large amounts of heterogeneous geospatial data including global, fine-scale satellite image data streams, census data, and crowd sourced or volunteered geographic information sources.

GHS城市中心数据库(GHS Urban Centre Database, GHS-UCDB)对被称为“城市中心”的空间实体进行了定义,其基于全球人类居住区图层(Global Human Settlement Layer, GHSL)的多时态专题属性集合,并结合其他免费开放数据集构建而成。该数据库是欧盟委员会开发的全球数据集,涵盖超过1万个城市中心,采用全球统一的方法学生成多时态、多专题信息,可支撑政策框架的全球监测,并为城市研究提供数据支持。其空间分辨率为1千米。本图层覆盖地理学与气候学两大专题领域,在此框架下,GHS-UCDB整合了多类指标族与指标,进一步细分为具体属性,且具备多时态属性(时间跨度为1970年至2070年)。属性内容涵盖生物群系分类、生态区、土壤类别、气候指标与气候带。 ### 柯本-盖格(Köppen-Geiger)分类说明 一级分类: A(热带气候): f(热带雨林气候)、m(季风气候)、w(热带草原气候,冬季干燥)、s(热带草原气候,夏季干燥) B(干旱气候): W(荒漠干旱气候)、S(半干旱草原气候); 温度细分:h(炎热)、k(寒冷) C(温带气候): w(冬季干燥)、f(无干季)、s(夏季干燥); 夏季温度细分:a(炎热夏季)、b(温和夏季)、c(寒冷夏季) D(大陆性气候): w(冬季干燥)、f(无干季)、s(夏季干燥); 夏季温度细分:a(炎热夏季)、b(温和夏季)、c(寒冷夏季)、d(冬季极寒) E(极地气候): T(苔原气候)、F(冰盖气候) 资料来源:维基百科 ### 附加信息 全球人类居住区图层(GHSL)项目旨在生成全球空间信息、基于实证的分析结果,以及描述全球人类活动分布的知识库。该项目依托空间数据处理技术的设计与实现,可对海量异构地理空间数据进行自动化分析与信息提取,数据源包括全球高分辨率卫星影像数据流、人口普查数据,以及众包或志愿地理信息来源。更多信息请点击此处。 资料来源:全球人类居住区——城市中心数据库R2024A - 欧盟委员会 | 最后访问时间:2025年11月6日 数据集版本:2025年版 数据处理(Esri德国):将GeoPackage导入ArcGIS Pro,转换为Web Mercator投影的文件地理数据库,优化了属性名称(别名)与字段类型,并将该图层作为要素服务发布至ArcGIS Online。
