OGC Services

EMODnet Bathymetry data can be used by accessing her OGC compliant web services. Currently, the following services are available:

To use EMODnet Bathymetry data in an external application connect to the one of the available service urls. Connection should work in browser clients as OpenLayer or leaflet.

Example Openlayers WMS layer [run example]
var layer = new ol.layer.Image({
	extent: [-36, 25, 43, 85],
	source: new ol.source.ImageWMS({
		url: 'http://ows.emodnet-bathymetry.eu/wms',
		// refer to the section layer name to find the name of the layer 
		params: {'LAYERS': 'mean_atlas_land'}			
	})
}); 

var map = new ol.Map({
layers: [ layer ],
target: 'map',
controls: ol.control.defaults(),
view: new ol.View({	
		projection: 'EPSG:4326',
		center: [5, 47],
		zoom: 5
	})	
});
Example Openlayers WMTS layer [run example]
var inspireWgs84Grid = function(levels, prefix) {
	var projection = ol.proj.get('EPSG:4326');

	var projectionExtent = projection.getExtent();
	var resolution = ol.extent.getWidth(projectionExtent) / 512;
	
	var resolutions = new Array(levels);
	var matrixIds = new Array(levels);
	
	for (var z = 0; z < levels; z++) {
		resolutions[z] = resolution / Math.pow(2, z);
		matrixIds[z] = z;
	}
	
	return new ol.tilegrid.WMTS({
		origin: ol.extent.getTopLeft(projectionExtent),
		resolutions: resolutions,
		matrixIds: matrixIds
	});				
}

var layer = new ol.layer.Tile({
	extent: [-36, 25, 43, 85],
	source : new ol.source.WMTS({
		url : 'http://tiles.emodnet-bathymetry.eu/v8/{Layer}/{TileMatrixSet}/{TileMatrix}/{TileCol}/{TileRow}.png',
		layer : 'mean_rainbowcolour',
		requestEncoding : 'REST',
		matrixSet : 'inspire_quad',
		format : 'image/png',
		projection : "EPGS:4326",
		tileGrid : inspireWgs84Grid(12, '')
	})
});

var map = new ol.Map({
	layers: [ layer ],
	target: 'map',
	controls: ol.control.defaults(),
	view: new ol.View({	
		projection: 'EPSG:4326',
		center: [5, 47],
		zoom: 5
	})	
});
Example Openlayers WFS layer [run example]
var source = new ol.source.Vector({
	format: new ol.format.GeoJSON(),
	url: function(extent) {
		return 'http://ows.emodnet-bathymetry.eu/wfs?service=WFS&' +
			'version=1.1.0&request=GetFeature' +
			// layer name comes here
			// refer to available layers to pick a layer
			'&typename=products&' + 
			'outputFormat=application/json&srsname=EPSG:4326&' +
			'bbox=' + extent.join(',') + ',EPSG:4326';
		},
	strategy: ol.loadingstrategy.bbox
});


var layer = new ol.layer.Vector({
	source: source,
	style: new ol.style.Style({
		stroke: new ol.style.Stroke({
	    color: 'rgba(0, 0, 255, 1.0)',
	    	width: 2
	    })
	})
});

var map = new ol.Map({
	layers: [ layer ],
	target: 'map',
	controls: ol.control.defaults(),
	view: new ol.View({	
		projection: 'EPSG:4326',
		center: [5, 47],
		zoom: 5
	})	
});	
				

REST service

For retrieving depth samples, a rest service is available

This rest service has two operations:

  • point
  • profile
Sample REST point request
GET /depth/point?geom=POINT(-9.7998046875 36.14501953125) HTTP/1.1
Host: rest.emodnet-bathymetry.eu
Content-Type: application/json; charset=utf-8
Sample REST point response
