青海省海北州建筑物空间分布数据研发(2020)

Development of Spatial Distribution Dataset of Buildings in Haibei Prefecture,Qinghai Province(2020)

海北藏族自治州(以下简称海北州)位于青海省东北部,是青海省发生地震较多的区域之一,其中门源发生过多次大的地震,最近一次是发生在2022年1月8日门源6.9级地震。在地震中,建筑物作为最重要的承灾体底数之一,数据比较缺少。基于阿里云的AI Earth平台和欧空局的10-m分辨率的土地利用数据,以采用2020年7月0.6-m的高分辨率影像,并结合土地利用中的建设用地数据为基础,来提取了海北州各县城内的建筑物;最后,得到了海北州区域建筑物的空间分布数据集(2020),包括祁连县、门源县、刚察县和海晏县的建筑数据。数据集存储为.shp格式,数据量为9.18 MB(压缩为1个文件,共3.55 MB)。

Haibei Tibetan autonomous prefecture(hereinafter referred to as Haibei prefecture)is located in the northeastern part of Qinghai province,and is one of the regions where more earthquakes occur in Qinghai province,Among them,Menyuan has been the site of several major earthquakes,the most recent of which occurred on January 8,2022 with a magnitude of 6.9 in Menyuan.In earthquakes,there is a lack of data on buildings as one of the most important substrates of disaster-bearing bodies.Based on Al Earth platform of Ali cloud and EsA's 10-m resolution land use data,the buildings within the counties of Haibei prefecture were extracted by using the 0.6 m high resolution image of July 2020 and combined with the construction land use data in the land use.Finally,the spatial distribution dataset of regional buildings in Haibei prefecture(2020)was obtained,including building data of Qilian county,Menyuan county,Guncha county and Haiyan county.The dataset is archived in.shp format with data size of 9.18 MB(compressed into 1 file,3.55 MB in total).
