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.本数据集涵盖博尔扎诺-南蒂罗尔自治省1997年、2005年与2017年三个参考年份的统一标准化冰川编目，数据格式为ESRI形状文件（ESRI-shapefile）。该类形状文件配套包含一份微软Excel（MS Excel）文件，用于分析各期冰川编目间的变化情况，同时还附带一份详细技术报告，对本次冰川编目及其依托的基础数据与研究方法进行完整说明。 本次冰川编目基于正射影像与机载激光扫描数据，采用统一标准化的编制方法完成，以确保各期编目之间可直接开展对比分析。除矢量化冰川轮廓及若干标识信息（冰川名称与世界冰川监测服务/冰川编目通用代码（WGMS/CGI codes））外，该编目还提供冰川面积、最大/最小及中位海拔、主要坡向、坡度与地理位置等典型地形参数信息。
