Flood_WFS – Surface Usage_HQ100 – OGC API Features

The map service (WFS group) presents selected spatial data from the area of flooding.:The flood risk map HQ100 shows the land use of flooded areas in events that can occur on a statistical average every 100 years. The following classes of use were distinguished: Class 1: Residential areas, mixed use areas (red); Class 2: agricultural land, forest, forest (yellow); Class 3: other vegetation and open spaces (green); Class 4: Industrial and commercial areas, Fl. with functional embossing (magenta); Class 5: Traffic areas (grey); Class 6: Areas of water (blue); In the case of dyke protected areas, the number 10 was entered in the Protection field and added it, so that according to the above sequence, classes 11 to 16 for the protected areas. These are shown with the same color, but not flat, but hatched. The classification was carried out by summaries from the ATKIS types by type of economic activity in accordance with the requirements of the LAWA draft of 25/26.03.2010 Dresden "Recommendations for the preparation of flood hazard maps and flood risk maps. Attributes: USAGE: Description of the usage class SCHUTZ: Protection status (0 = no; 10 = yes) CLASS: Risk class Gewaesser: Water name GEWKZ: Water code; Scale limitation: Min not required, Max 1:3000.地图服务（WFS，Web Feature Service）组展示了洪涝区域的精选空间数据： 洪涝风险地图HQ100展示了每百年一遇统计频次的洪涝事件中受淹区域的土地利用类型。本次划分了如下用地类别： 类别1：居民区、混合功能区（红色）； 类别2：农用地、林地、森林（黄色）； 类别3：其他植被与开阔空地（绿色）； 类别4：工商业区域、带有功能标识的地块（品红色）； 类别5：交通用地（灰色）； 类别6：水体区域（蓝色）； 针对堤防保护区，在保护状态字段中赋值为10并叠加该分类体系，因此保护区对应的类别为11至16。此类别采用与对应常规类别相同的配色，但填充样式并非纯色，而是采用晕线填充。 本次分类依据2010年3月25日至26日在德累斯顿发布的LAWA草案《洪涝灾害地图与洪涝风险地图编制建议》中的要求，通过按照经济活动类型对ATKIS（通用地形测绘与信息系统）类型进行归并完成。 字段说明： USAGE：用地类别说明 SCHUTZ：保护状态（0=无保护；10=有保护） CLASS：风险等级 Gewaesser：水体名称 GEWKZ：水体代码 比例尺限制：无最小比例尺要求，最大比例尺为1:3000。
