Bathymetric datasets are an extraction of surveys belonging to the Shom public database. For depth up to 50m, the vertical precision of soundings varies from 30cm to 1m and the horizontal precision varies from 1 to 20m. In deep ocean, the vertical precision is mainly around 1 or 2% of the bottom depth. It is sometimes more, it depends on the technology used. The data are referenced to ZH which is assimilated to LAT. Data are corrected for sound velocity variations.

One aerial photograph (IGNF_PVA_1-0__1969-09-18__C92PHQ5671_1968_GUY19P_0141) acquired by Institut Géographique National (IGN). The image covers the area around Renner change in French Guiana. We used the image for the project "Feasibility study of the implementation of forest firewalls on the Guyanese Space Center".

The aerial laser scanning (ALS) dataset acquired on 20 October 2015 covers the experimental station Paracou in French Guiana. The coverage includes all Guyafor and Guyaflux plots completely with logged-over, unlogged and swamp forest ("Pinot" or "Açai").

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.
