The homogenized glacier inventories for South Tirol 1997-2005-2017

Data set of three homogenized glacier inventories for the Autonomous Province of Bolzano - South Tyrol for the reference years 1997, 2005 and 2017 in ESRI-shapefile format. The shapefiles are supplemented by a MS-excel file containing analyses of glacier changes between the single inventories and a detailed technical report describing the inventories and the underlying data and methods. The inventories were compiled based on orthophoto and airborne laser-scanning data using a homogenized methodology to enable for direct comparisons between the single inventories. Besides the vectorized glacier outlines and several identifiers (glacier names and WGMS/CGI codes), the inventories provide information on typical topographic parameters such as glacier area, min max and median altitude, main aspect, slope and geographic location.本数据集包含针对博尔扎诺-南蒂罗尔自治省（Autonomous Province of Bolzano - South Tyrol）1997年、2005年及2017年三个参考年份的三份均质化冰川名录，数据格式为ESRI形状文件（ESRI-shapefile）。该套形状文件配套包含三份冰川名录间变化分析结果的Microsoft Excel表格，以及一份详述该冰川名录、底层数据与编制方法的详细技术报告。三份冰川名录均基于正射影像与机载激光扫描数据，采用统一均质化方法编制，以确保各名录间可直接开展对比分析。除矢量化冰川边界与若干标识符（冰川名称及WGMS/CGI代码）外，该冰川名录还提供了冰川面积、最小海拔、最大海拔、海拔中位数、主导坡向、坡度及地理位置等典型地形参数信息。
