LstG skyfall mapping Växjö runway

Surface runway paths are classified hierarchically according to how they flow together, light blue is the first surface runway and darker colors for each new surface runway that flows together. The surface drainage paths are developed according to the first version of Jönköping’s “skyfall mapping in GIS – Working Method and Method, Communication No 2014:28 method for skyfall mapping” and is based on Lantmäteriet’s elevation model, buildings in the property map and lakes and watercourses. The analysis does not take into account stormwater systems or soil infiltration capacity. Culverts and smaller structures such as curbs that have a major influence on the runway are not included in the elevation model and the runway should therefore be interpreted with caution. The data generally provides a first overview of possible problem areas.地表径流路径依据汇流关联关系进行分级分类，浅蓝色用于标注第一条地表径流路径，每一条与之汇流的新增地表径流路径依次使用更深的色系表示。本地表排水路径数据集依据延雪平市（Jönköping）发布的《GIS降雨制图（skyfall mapping）——工作方法与流程，通讯编号2014:28》第一版方法构建，数据基础涵盖瑞典国家土地测量局（Lantmäteriet）的高程模型、地籍图中的建筑物信息以及湖泊与河道数据。本次分析未考虑雨水管网系统与土壤入渗能力。涵洞及路缘石等对地表径流路径存在显著影响的小型构筑物未被纳入高程模型，因此对该数据集的解读需格外谨慎。本数据集整体可作为潜在问题区域的初步概览参考。
