EMODnet Bathymetry REST service

EMODnet Bathymetry provides a rest service to retrieve depth samples. Currently, two operations are availble to query the EMODnet DTM for depth samples:

  • /depth_sample - retrieve a depth sample for a single grid cell
  • /depth_profile - retrieve an intersection of depth samples along a line

/depth_sample

This method returns the attributes of a single DTM grid cell for a single coordinate. Input parameter geom is a WKT Point geometry in geographic coordinates.

Sample REST point request [run example]
GET /depth_sample?geom=POINT(3.3233642578125 55.01953125) HTTP/1.1
Host: rest.emodnet-bathymetry.eu

  }
}

/depth_profile

This method returns a intersection of the DTM along the requested LineString. Input parameter geom is a LineString WKT geometry in geographic coordinates

Sample REST profile request [run example]
GET /depth_profile?geom=LINESTRING(-7.7783203125 49.02099609375,-9.9755859375 46.42822265625) HTTP/1.1
