  • Information layer containing the SAR Zones (Search and Rescue). This layer contains a description of the French search and rescue (SAR) areas and the location of the associated Maritime Rescue Coordination Center (MRCC). it covers the areas of responsibility of France. The layer was produced by the Shom pursuant to the Circular Circular of the International Maritime Organization (IMO No. SAR.8 / Circ.4 of 1 December 2012).

  • Marine toponymy data layer obtained from French ENC and created using the S23 (4th edition, June 2002). Note: The usual Sea of Japan designation does not imply taking a stand in the dispute between Korea, which names this sea "East Sea", and Japan, which names it "Sea of Japan".

  • "Harbour Information" product contains 13 object classes, the acronyms used are those of IHO standard S-57 - International Hydrographic Organization – (https://iho.int/): - Berth (BERTHS): place in which a ship is moored at wharf - Isolated building localizing a harbour office (BUISGL) - Checkpoint (CHKPNT) - Crane (CRANES) - Floating dock (FLODOC): floating structure of one or more sections which can be partly submerged by controlled flooding to receive a vessel, then raised by pumping out the water so that the vessel's bottom can be exposed for maintenance. - Gridiron (GRIDRN): structure in the intertidal zone serving as a support for vessels at low tide to permit work on the exposed portion of the vessel's hull. - Harbour area (HRBARE) : administrative area of a port, including all docking and handling facilities, as well as short-term storage facilities. - Harbour facility (HRBFAC) - Hulk (HULKES) : hull of a wrecked or condemned ship, from which the fittings and superstructure have usually been removed, which is moored in a permanent position or grounded. - Oil barrier (OILBAR) - Pilot boarding place (PILBOP) - Rescue station (RSCSTA) - Small craft facility (SMCFAC) Detailed definitions of each of these object classes can be found in the S-57 standard (https://iho.int/en/standards-and-specifications). An online catalog is available at http://www.s-57.com/. Some of the symbols used for display on data.shom.fr portal have been adapted from icons from the OpenSeaMap open library (https://github.com/OpenNauticalChart/).

  • "Regulation - Navigation" product contains 18 object classes, the acronyms used are those of IHO standard S-57 - International Hydrographic Organization – (https://iho.int/): - Anchorage area (ACHARE): an area in which vessels anchor or may anchor. - Anchor berth (ACHBRT): a designated area of water where a single vessel, sea plane, etc. may anchor. - Administration Area (Named) (ADMARE) - Cable area (CBLARE) - Coastguard station (CGUSTA) - Cargo transhipment area (CTSARE) - Distance mark (DISMAR): mark indicating the distance on canals or rivers. - Dumping ground (DMPGRD): sea area where dredged material or other potentially more harmful material e.g. explosives, chemical waste, is deliberately deposited. - Fairway (FAIRWY): part of a river, harbour etc. where the main navigable channel for vessels of larger size lies. It is also the usual course followed by vessels entering or leaving harbours and sometimes called "ship channel". - Ice area (over land or water) (ICEARE) - Local magnetic anomaly (LOCMAG): anomaly of the magnetic field of the earth, extending over a relatively small area, due to local magnetic influences. - Marine farm/culture (MARCUL) - Navigation line (NAVLNE): a line generally passing through two clearly defined charted landmarks, and along part of which a vessel can approach safely. - Pipeline area (PIPARE) - Recommended track (RECTRC): track of undefined width, recommended to all or only certain vessels. - Restricted area (RESARE): specified area designated by an appropriate authority within which navigation is restricted in accordance with certain specified conditions. - Sea-plane landing area (SPLARE) Detailed definitions of each of these object classes can be found in the S-57 standard (https://iho.int/en/standards-and-specifications). An online catalog is available at http://www.s-57.com/. Some of the symbols used for display on data.shom.fr portal have been adapted from icons from the OpenSeaMap open library (https://github.com/OpenNauticalChart/). For reasons of readability, not all the characteristics of the objects are systematically displayed. All available information can be consulted by querying this layer.

  • Subset of the Pléiades image that covers the experimental station Paracou in French Guiana.

  • This database contains botanical records either relating to material present in one of the Naturalis collections, or to material that has been or is being used in research projects. The records usually relate to herbarium specimens, but it also contains data on silica-gel samples, wood samples, spirit collections, carpological collections, etc.; rarely to observations only. The Naturalis collections have their strong points in The Netherlands and surrounding countries, Southeast Asia and New Guinea, West- and Central-Africa, Ethiopia and the Guyanas.

  • This product shows the international distribution of types of tides. Four types of tides exist, and are classified based on the number and height of high and low waters each day: semi-diurnal tide: two high tides and two low tides with approximately the same height are recorded each day. Mixed tides with diurnal inequality: two high and low tides are recorded daily (just like with semi-diurnal tides), however the heights of the high and low waters vary significantly over the same day. Diurnal tides: one single high tide and one single low tide are recorded each day. Composite: tides can be diurnal or semi-diurnal or mixed.

  • Guyadiv is a network of permanent forest plots installed in French Guiana. The site of Guyadiv in Counami is composed of 19 1200sq.m-plots. A complete inventory has been made on these plots, during 3 inventory sessions in 2000, 2001 and 2002. 1743 trees have been inventoried, with 92,2% to 100% of trees identified to species level. We only have the point coordinates and not the precise demarcation of the sample plots. In order to calculate the bounding box for these plots, we have expanded the point location 500 meters in each direction.

  • The site Quartzites is composed of two 3km-transects (20m wide). 2638 trees with dbh>=20cm have been recorded by Office national des forêts (ONF). No fauna inventories available. 276 under-storey plants have been recorded on 17 25m²-plots by Institut de recherche pour le développement (IRD). Soils have been described using 13 samples (1.20m depth max.) and two soil pits (1.50m depth). Laboratory analyses are available for one profile and for the two soil pits
