Map Viewing Service (WMS) of the dataset: Ad hoc prescription of the PLU of the municipality of Saint Valery sur Somme

The requirements of an urban planning document are defined in Article R123-11 of the Urban Planning Code. A prescription is in the form of surface, linear or point information which appears on the graphic documents of the PLU or the POS. A prescription which superimposes on an area of the planning document generally imposes an additional constraint on the regulation of the area.《城市规划法典（Urban Planning Code）》第R123-11条明确了城市规划文件的各项要求。规划规制条款以面状、线状或点状信息的形式呈现，载于地方城市规划（PLU）或土地利用规划（POS）的规划图件之中。叠加于规划文件某一区域之上的规制条款，通常会对该区域的规划管控规则施加额外约束条件。
