diFUME Urban Morphological and Roughness Indicators V0.1
收藏资源简介:
Description: Urban morphological and roughness indicators for Basel at 100 m resolution. The mean (zH), maximum (zHmax) and standard deviation (zHstd) of building height, the plan area index (pai - corresponding to the fraction of roof area), the frontal area index (fai - defining the area of building walls relative to total ground area), the roughness length (zo) and the zero-plane displacement height (zd) are calculated isotropically (i.e. all directions are integrated into one value for each parameter) for the study area using UMEP Morphometric Calculator. Roughness parameters (zo, zd) are calculated using the real urban surfaces parameterization of Kanda et al. (2013). The Digital Surface Model (V0.1) for buildings and terrain is used. Data specifications: CRS: EPSG:32632 - WGS 84 / UTM zone 32N - Projected Spatial Extent: 392120.0,5266940.0 : 395120.0,5269840.0 Temporal Extent: 2015 - 2019 Units: meters Width: 30 Height: 29 Bands: 1 Pixel Size: 100,-100 Data type: Float32 - Thirty two bit floating point GDAL Driver Description: GTiff GDAL Driver Metadata: GeoTIFF
数据集描述:巴塞尔市100米分辨率的城市形态与粗糙度指标。本数据集借助UMEP形态学计算器(UMEP Morphometric Calculator)对研究区开展各向同性计算——即针对每个参数整合所有方向信息以得到单一数值——,涵盖建筑高度的均值(zH)、最大值(zHmax)与标准差(zHstd),平面面积指数(pai,对应屋顶面积占比),正面面积指数(fai,指建筑墙面面积与总地面面积的比值),粗糙度长度(zo)与零平面位移高度(zd)。其中粗糙度参数(zo、zd)基于Kanda等人2013年提出的真实城市地表参数化方案计算,所用基础数据为建筑与地形的数字地表模型(Digital Surface Model, V0.1)。 数据规格如下:坐标系(Coordinate Reference System, CRS):EPSG:32632——WGS 84 / UTM 32N 投影坐标系;空间范围:392120.0,5266940.0 至 395120.0,5269840.0;时间范围:2015年—2019年;单位:米;幅宽:30,幅高:29;波段数:1;像素尺寸:100,-100;数据类型:Float32——32位浮点型;GDAL驱动描述:GTiff;GDAL驱动元数据:GeoTIFF。
