Map Viewing Service (WMS) of the dataset: Easements to protect radio reception centres against electromagnetic disturbances (PT2) in Seine-et-Marne

Unofficial data, digitised from administrative documents collected by DDT 77, contact the manager or consult the GPU to obtain data that can be used in a regulatory framework. The generator: Transmission and reception centres/stations: the generator is either a polygon object or a point

In order to ensure the proper functioning of the networks, easements are hereby established pursuant to Articles L. 54 to L. 56-1 of the Postal and Electronic Communications Code in order to protect radio centres from physical obstacles which may hinder the spread of waves.The limit of the radio centre is the contour of the minimum surface polygon encompassing all existing or projected radiating elements or collectors. However, the area of a centre may not exceed a certain area. The distance between any two points of the contour representing the centre boundary shall not exceed 2,000 metres. Otherwise, all radiating elements or collectors must be divided into several islets whose specific limits meet this condition. The area of easement is then determined from the limit of each of these islets.The generator of a public easement is a geographical entity whose nature or function induces, by regulation, constraints on the way the land is occupied on the surrounding land.The disappearance or destruction on the site of the generator does not result in the removal of the easement(s) associated with it. Only a new act of annulment or repeal by the competent authority may legally remove the effects of the easement(s) in question.

本数据集为非官方数据，源自DDT 77收集的行政文件数字化成果；若需获取可用于合规监管框架的数据，请联系管理人员或咨询GPU。生成要素说明：传输与接收中心/基站的生成要素可表现为多边形对象或单点。为保障通信网络的正常运行，依据《邮政与电子通信法典》第L.54条至第L.56-1条之规定，设立通信地役权（easement），以保护无线电中心免受可能阻碍电波传播的实体障碍物干扰。无线电中心的边界为覆盖所有现有或规划中辐射单元与采集单元的最小表面积多边形轮廓。不过，无线电中心的面积不得超出规定上限。代表中心边界的轮廓线上任意两点间的距离不得超过2000米；若无法满足该条件，则需将所有辐射单元与采集单元划分为若干符合该边界距离要求的子区块，通信地役权的范围将依据各子区块的边界分别确定。公共地役权的生成要素为一类地理实体，其属性或功能依法律法规对周边土地的使用方式施加约束。生成要素所在场地的灭失或损毁，不会导致与之关联的地役权自动消灭；仅有权主管部门作出新的废止或撤销决定，方可依法终止相关地役权的效力。
