WMS Service (Web Map Service) Strategic Noise Maps (MER) 3 rd Phase_Agglomerations_Ld

The WMS Service (Web Map Service) called “MER.Agglomerations Ld” allows the visualisation and consultation of the data set representing the Ld index isophone lines corresponding to the strategic noise maps (MERs) of the agglomerations that are to be drawn up in accordance with Directive 2002/49/EC on the assessment and management of environmental noise because they have a population of more than 100,000 inhabitants. 3 rd phase of the implementation of Directive (2017). The information published in this cartography corresponds to that which had been communicated to the Ministry by the different competent authorities at the end (November) of 2021. The URL of the service is as follows: https://wms.mapama.gob.es/sig/EvaluacionAmbiental/Ruido/MER/Aglomeraciones/Ld/wms.aspx The reference systems offered by this service are: — For geographical coordinates: CRS: 84, EPSG:4230 (ED50), EPSG:4326 (WGS 84), EPSG:4258 (ETRS 89). — For U.T.M coordinates: EPSG:32627 (WGS 84/UTM zone 27N) EPSG:32628 (WGS 84/UTM zone 28N), EPSG:32629 (WGS 84/UTM zone 29N), EPSG:32630 (WGS 84/UTM zone 30N), EPSG:32631 (WGS 84/UTM zone 31N), EPSG:25828 (ETRS 89/UTM zone 28N), EPSG:25829 (ETRS 89/UTM zone 29N), EPSG:25830 (ETRS 89/UTM zone 30N), EPSG:25831 (ETRS 89/UTM zone 31N), EPSG:23028 (ED50/UTM zone 28N), EPSG:23029 (ED50/UTM zone 29N), EPSG:23030 (ED50/UTM zone 30N), EPSG:23031 (ED50/UTM zone 31N), EPSG 3857 (WGS84/Web Mercator)名为"MER.Agglomerations Ld"的网络地图服务（Web Map Service，WMS）可实现对应数据集的可视化与查询，该数据集包含符合《关于环境噪声评估与管理的2002/49/EC号指令》要求的城市群战略噪声地图（MERs）对应的Ld指数等声级线，此类城市群人口规模均超过10万，本服务属于2017年指令实施的第三阶段。 本次发布的该制图成果的信息，为各主管部门于2021年末（11月）提交至相关主管部门的相关数据。 该服务的访问URL如下：https://wms.mapama.gob.es/sig/EvaluacionAmbiental/Ruido/MER/Aglomeraciones/Ld/wms.aspx 本服务提供的坐标参考系统如下： — 地理坐标参考系：CRS:84、EPSG:4230（ED50）、EPSG:4326（WGS 84）、EPSG:4258（ETRS 89） — UTM坐标参考系：EPSG:32627（WGS 84/UTM 27N带）、EPSG:32628（WGS 84/UTM 28N带）、EPSG:32629（WGS 84/UTM 29N带）、EPSG:32630（WGS 84/UTM 30N带）、EPSG:32631（WGS 84/UTM 31N带）、EPSG:25828（ETRS 89/UTM 28N带）、EPSG:25829（ETRS 89/UTM 29N带）、EPSG:25830（ETRS 89/UTM 30N带）、EPSG:25831（ETRS 89/UTM 31N带）、EPSG:23028（ED50/UTM 28N带）、EPSG:23029（ED50/UTM 29N带）、EPSG:23030（ED50/UTM 30N带）、EPSG:23031（ED50/UTM 31N带）、EPSG:3857（WGS84/网络墨卡托）
