Inspire SL Hydro — Physical waters ATKIS DLM50

This INSPIRE dataset contains the Saarland water network. The transformation was carried out in accordance with the INSPIRE Hydrography guidelines in version 4.0. The following application schemes are currently being provided on this topic: * Hydrography Physical Waters * Hydrography Networks The scheme Hydrography Physical Waters The application scheme of Physical Waters is mainly used to create base maps for hydrography. The selection of feature classes in this package is based on both the requirements for assigning certain objects and the need to distinguish specific objects according to a modeling aspect. As a result, certain characteristics of the “real world” are grouped into a single class when it has been found that they do not have to be distinguished from the point of view of mapping or from the point of view of modelling. The following groups of objects can be distinguished: * Natural water objects that are part of the hydrological network, such as watercourses, standing water, wetlands, etc. * Objects describing the physical water objects (banks, shorelines) * Areas in which the water is caught (river basin/dewatering basin) * Hydrographic points of interest. Points that affect the flow of water in the water network and appear on maps but are not artificial objects (e.g. falls, sources and seepage, etc.). * Artificial objects. All objects that must be indicated on the map and have a relationship with the water network (e.g. embankments, canals, locks, dams and weirs). The Hydrography Networks Schema requires additional information (e.g. closed network, certain attributes) that are not necessarily required for a background map. This additional information as well as the network model itself are therefore included in a separate application scheme, which can be regarded as an extension of the physical waters. If only one network model is available with the data provider, it is possible to describe the network without directly referring to physical objects. For this reason, spatial objects contain their own geometries both in the network model and in the physical hydrography schemes.本INSPIRE数据集包含萨尔兰水网。本次数据转换严格遵照4.0版《INSPIRE水文指南》（INSPIRE Hydrography guidelines）开展。当前针对该主题提供以下应用方案： * 水文实体水域（Hydrography Physical Waters） * 水文水网（Hydrography Networks） 水文实体水域应用方案 该应用方案主要用于构建水文基底地图。本数据包内要素类的选取，同时兼顾特定对象的赋值需求，以及基于建模维度区分具体对象的需要。据此，若从制图或建模视角无需对某类"现实世界"特征进行区分，则将其归为单一要素类。可区分的对象群组如下： * 属于水文网络的自然水体对象，如河道、静水面、湿地等； * 描述实体水域的物理对象（岸线、堤岸）； * 水体汇水区（流域/泄水区）； * 水文兴趣点：对水网水流产生影响、可在地图上标注但非人工建造的对象（例如瀑布、水源与渗流点等）； * 人工设施对象：所有需在地图上标注且与水网存在关联的人工对象（例如堤坝、运河、船闸、挡水坝与堰闸等）。 水文水网应用方案 该方案需额外信息（例如闭合水网、特定属性），此类信息并非基底地图的必备要素。因此，这类额外信息及水网模型本身被纳入独立的应用方案，可视为水文实体水域方案的扩展。若数据提供者仅提供单一水网模型，则可在不直接引用实体对象的前提下对水网进行描述。基于此，空间对象在水网模型与水文实体水域方案中均包含自身几何信息。
