Data and map services

All spatial datasets used and produced by HELCOM in its assessments can be accessed and downloaded from HELCOM Metadata catalogue and viewed in HELCOM Map and Data service.

HELCOM Map and Data service is a graphical user interface containing a table of contents of all spatial datasets made available by HELCOM and relevant to HELCOM work. The service contains many functionalities that could be used when viewing the datasets, e.g. identify and attribute table functionalities. The datasets are grouped to following services, which contain a number of map layers grouped in to categories (group layers):

Status assessments: Integrated assessment results, core indicator result maps and underlying datasets
Monitoring: Assessment units according to HELCOM Monitoring and Assessment Strategy and monitoring stations used in HELCOM Monitoring manual
Pressures and human activities: Land-based pollution as well as various human activities datasets and aggregated pressure layers used in Baltic Sea Impact and Pressure Index (BSPI and BSII).
Biodiversity: Biodiversity related datasets such as Ecosystem component maps used in Baltic Sea Impact and Pressure Index (BSPI and BSII), HELCOM RED LIST species/biotope distribution maps as well as other biota related datasets.
Shipping: Maritime activities related datasets, including data from HELCOM Maritime assessment such as AIS density maps by ship type.
Background: Background datasets such as rivers, lakes, EEZ as well as Maritime Spatial Plannig areas.

All HELCOM datasets are also listed in HELCOM Metadata catalogue, which contains INSPIRE compliant metadata record of the dataset, download functionality (zip package containing shapefile / TIFF) and URL to view the dataset in HELCOM Map and Data service.

DATA SERVICES

HELCOM provides direct access to all HELCOM geospatial datasets either by ArcGIS Rest interface or INSPIRE compliant OGC WMS Standard:

ArcGIS Rest interface address: http://maps.helcom.fi/arcgis104/rest/services/MADS

OGC WMS (1.3.0) interface addresses:

Status assessments: http://maps.helcom.fi/arcgis104/services/MADS/Sea_environmental_status/MapServer/WMSServer?request=GetCapabilities&service=WMS

Sea Environmental monitoring: http://maps.helcom.fi/arcgis104/services/MADS/Sea_environmental_monitoring/MapServer/WMSServer?request=GetCapabilities&service=WMS

Background: http://maps.helcom.fi/arcgis104/services/MADS/Background/MapServer/WMSServer?request=GetCapabilities&service=WMS

HELCOM WMS service is currently created with ArcGIS Server 10.4 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: 4386 (WGS84)
EPSG: 32633 (WGS 84 / UTM zone 33N)
EPSG: 3857 (WGS84 Web Mercator)
EPSG: 3006 (SWEREF99TM)
EPSG: 3067 (ETRS89 / ETRS-TM35FIN)

The following web map portals are currently displaying map data from HELCOM via WMS connection:

EMODnet biology

Swedish Water information system (VISS, available only in swedish)

The Swedish Agency for Marine and Water Management (Havsplanering, available only in swedish)

Finnish national geospatial portal (Paikkatietoikkuna, available only in finnish)
