The REFMAR dissemination of tidal data is transfered to the site http://data.shom.fr, the marine and coastal geographic information portal
Bannière data.shom.fr

REFMAR and data.shom.fr staff are available to help you make the switch and answer all your questions.

Any application for registration or account changes are no longer taken into account.

SML file format accompanying each data file

The format of the SML (Sensor Markup Language) file is an approved OGC (Open Geospatial Consortium) standard that provides a standard model encoded in XML to describe sensors and measurement processes. This file is present every time you download a data file in any format (TXT, XML or JSON).

 

SML format:

The SML file is an XML file consisting of several sections:

Section   <sml:keywords> :

Not applicable

 

Sections  <sml:identification> et <sml:classification> :

These two sections contain the number and name of the observatory provided respectively by:

<sml:identifier name="uniqueID"> and <sml:identifier name="longName">

                        <sml:classifier name="value"> and <sml:classifier name="label">

Section  <Capabilities>:

This section provides a great deal of information on the observatory:

  • The city where the observatory is located;
  • The time system (XXXXXXXXXXXXXXXXXXXXX);
  • The geographic coordinates of the observatory (WGS84);
  • The geographical area: FM: Metropolitan France / Overseas???
  • The managing bodies of the observatory;
  • The date of the first water level observation;
  • Links to specific information on the observatory (inventory, vertical datum, sensor type, log). This information is present on the observatory information page on the REFMAR website;
  • Tide gauge status (this is also shown on the tide gauge page by a color-coded dot next to the name:
    • OK => green;
    • Problem => orange (maintenance);
    • Out of service => red
  • The name of the site used for calculating tidal predictions (element: SPM);
  • The height of the chart datum relative to the vertical datum (element: zh_ref);
  • The name of the vertical datum (element: ref_name);
  • The chart datum of the observatory.
