Synthesized Inventory of Relevant Infrastructure and Utilized Areas, Including Contaminated Sites (SIRIUS)
收藏资源简介：
The SIRIUS inventory integrates data from OpenStreetMap for infrastructure and land use information (OpenStreetMap Contributors and Geofabrik GmbH, 2018), the modeled Northern Hemisphere permafrost map by Obu et al. (2018), the contaminated sites database and reports by the State of Alaska Department of Environmental Conservation (2023) (DEC), the inventory of contaminated sites in Canada by the Treasury Board of Canada Secretariat (FCSI) (2024), a compilation of contaminated sites in Greenland and Norway from the NGO Robin des Bois (2009a, 2009b) (RdB), projections of the timing of first talik formation, a model output from the CryoGridLite permafrost model (Langer et al., 2024) for the Arctic regions of Alaska (AK), Canada (CA), Greenland (GL), and Norway (NO). This dataset is provided as a GeoPackage, enabling seamless integration with spatial databases (e.g., PostgreSQL/PostGIS), Geographic Information Systems (e.g., QGIS), and geospatial processing libraries (e.g., Python's GeoPandas). All layers can be queried either independently or in combination with one another. The GeoPackage contains 17 separate layers. The contaminated sites layers contain detailed information on contaminants haromized into chemical classifications based on the Agency for Toxic Substances and Disease Registry (ATSDR). Additionally, each contaminated sites layer includes projections of talik formation as complementary attributes. These projections are provided for SSP1-2.6 and SSP5-8.5 scenarios, specifying the 5th, 50th (median), and 95th percentiles of the year when talik formation is expected to occur for the first time. The layers of the infrastructure and human-impacted areas are further divided into points of interest (POI), polygonal infrastructure, and linear road and rail networks (RRNetwork) for each Arctic region (AK, CA, GL, and NO). The permafrost extent is provided as a single pan-Arctic layer.

SIRIUS 数据集整合了多源数据，具体来源包括： 用于获取基础设施与土地利用信息的OpenStreetMap数据（OpenStreetMap贡献者与Geofabrik GmbH，2018）、Obu等人（2018）构建的北半球多年冻土分布图、阿拉斯加州环境保护部（2023，简称DEC）的污染场地数据库与报告、加拿大国库委员会秘书处（2024，简称FCSI）发布的加拿大污染场地清单、非政府组织Robin des Bois（2009a、2009b，简称RdB）整理的格陵兰与挪威污染场地汇总数据，以及CryoGridLite多年冻土模型（Langer等，2024）输出的首次融区（talik）形成时间预测结果。 上述数据覆盖阿拉斯加（AK）、加拿大（CA）、格陵兰（GL）与挪威（NO）的北极区域。 本数据集以GeoPackage格式提供，可与空间数据库（如PostgreSQL/PostGIS）、地理信息系统（如QGIS）及地理空间处理库（如Python的GeoPandas）实现无缝集成。所有图层均可独立查询，亦可组合联动查询。 该GeoPackage共包含17个独立图层。其中，污染场地图层包含按照美国毒物与疾病登记署（Agency for Toxic Substances and Disease Registry, ATSDR）的化学分类标准完成统一标准化处理的污染物详细信息；此外，每个污染场地图层均附带首次融区形成时间预测作为补充属性，该预测针对SSP1-2.6与SSP5-8.5两种情景，给出了首次融区形成年份的5%、50%（中位数）与95%分位数。 基础设施与人类影响区域图层进一步划分为各北极区域（AK、CA、GL、NO）的兴趣点（Point of Interest, POI）、面状基础设施，以及线状道路与铁路网络（RRNetwork）。多年冻土分布范围以单个泛北极图层形式提供。 ### 污染场地图层 AK_ContaminatedSites_DEC CA_ContaminatedSites_FCSI GL_ContaminatedSites_RdB NO_ContaminatedSites_RdB ### 基础设施与人类影响区域图层 NO_POI_InfrastructureHIElements_OSM NO_InfrastructureHIElements_OSM NO_InfrastructureHIElements_RRNetwork_OSM GL_POI_InfrastructureHIElements_OSM GL_InfrastructureHIElements_OSM GL_InfrastructureHIElements_RRNetwork_OSM AK_POI_InfrastructureHIElements_OSM AK_InfrastructureHIElements_OSM AK_InfrastructureHIElements_RRNetwork_OSM CA_POI_InfrastructureHIElements_OSM CA_InfrastructureHIElements_OSM CA_InfrastructureHIElements_RRNetwork_OSM ### 多年冻土分布范围图层 PermafrostZones_UiO ### 数据下载 pan-arctic_SIRIUS_v1.0.gpkg
