HELCOM Map and Data Service (HELCOM MADS) contains all geospatial data
relevant for HELCOM work from status assessments to shipping density maps.
It is linked to the HELCOM Metadata catalogue to view INSPIRE compliant metadata and download datasets in shapefile or in TIFF format.
The service contains various functionalities for viewing datasets, for example, identify features and attribute table functionalities.
HELCOM provides direct access to all
HELCOM geospatial datasets either by ArcGIS Rest interface or INSPIRE compliant OGC WMS

HELCOM WMS service (1.3.0) is currently created with ArcGIS Server 10.6.1 and enabled for multiple spatial reference systems in order to provide data within national coordinate systems used by national web map portals. The coordinate systems currently provided are EPSG: 3035 (ETRS89LAEA, INSPIRE/EU recommended frame of reference for geodata for Europe); EPSG: 4326 (WGS84); EPSG: 3857 (WGS84 Web Mercator); EPSG: 3006 (SWEREF99TM) and EPSG: 3034 (ETRS89/LCC Europe).
