收藏资源简介:
这是一个基于2022年SPOT卫星数据制作的法国本土88个人口超过5万的城市区域的本地气候区(LCZ)地图数据集。该数据集用于大规模诊断城市热岛效应(ICU),提供考虑城市形态和土地利用的预气候诊断,旨在定位需要细化分析和优先行动的关键区域或街区。数据源包括Urban Atlas 2018(以及Cerema提供的5个未覆盖区域的数据:Arles、Cholet、La Roche-sur-Yon、Montauban、Narbonne)、DINAMIS框架下的2022年SPOT年度覆盖数据以及IGN的BD TOPO(2022年12月v3.3版)。数据集以每个城市区域的压缩包形式交付,包含:矢量LCZ地图(.shp)和QGIS符号系统(.qml)、栅格化LCZ地图(1.5米分辨率,.tif)和QGIS符号系统(.qml)、矢量LCZ地图的元数据(.xml)、城市区域数据地图(.pdf)以及交付和内容描述(.pdf)。此外,还提供在线可视化工具和覆盖城市区域的CSV文件列表。
This is a dataset of Local Climate Zone (LCZ) maps for the 88 urban areas with over 50,000 inhabitants in metropolitan France, produced from 2022 SPOT satellite data. The dataset is used for large-scale diagnosis of the Urban Heat Island (UHI) phenomenon, providing a pre-climatic diagnosis that considers urban morphology and land use, aiming to locate key areas or neighborhoods for refined analysis and prioritized actions. Data sources include Urban Atlas 2018 (and Cerema data for 5 areas not covered by Urban Atlas: Arles, Cholet, La Roche-sur-Yon, Montauban, Narbonne), the 2022 SPOT annual coverage data acquired under the DINAMIS framework, and IGNs BD TOPO (v3.3 from December 2022). The dataset is delivered as a compressed package per urban area, containing: vector LCZ maps (.shp) with QGIS symbology (.qml), rasterized LCZ maps (1.5m resolution, .tif) with QGIS symbology (.qml), metadata for the vector LCZ maps (.xml), a map presenting the data on the urban area (.pdf), and delivery and content descriptions (.pdf). Additionally, an online visualization tool and a CSV file listing the communes covered by each urban area are provided.
