WMS (Web Map Service) General Surveillance Chemical Control Network

The WMS Service (Web Map Service) called “General Surveillance Chemical Control Network” allows the visualisation and consultation of the dataset of the sampling stations of the general chemical surveillance control network. This network belongs to the groundwater monitoring network whose main objective is to generate the information necessary to carry out an effective management of the state of water bodies. They are a basic tool for decision-makers as they allow to evaluate the effectiveness of the measures adopted and the degree of compliance with the objectives set. The URL of the service is as follows: https://wms.mapama.gob.es/sig/Agua/CAS_Vigilancia/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“通用监测化学管控网络”的Web地图服务（Web Map Service，WMS），可实现通用化学监测管控网络采样站数据集的可视化展示与查询检索。该网络隶属于地下水监测网络，其核心目标是生成支撑水体状态有效管理所需的必要信息。对于决策者而言，该网络是一项基础性决策工具，可用于评估所采取管控措施的实施效果，以及既定目标的合规达标程度。 该服务的访问URL如下：https://wms.mapama.gob.es/sig/Agua/CAS_Vigilancia/wms.aspx 本服务支持的参考坐标系如下： — 地理坐标参考系：CRS:84、EPSG:4230（ED50）、EPSG:4326（WGS 84）、EPSG:4258（ETRS 89）。 — 通用横轴墨卡托（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/Web Mercator）
