  • The aerial laser scanning (ALS) dataset, acquired on 1 october 2005, covers five plots of the Montagne des Chevaux and the Montagnes des Serpents areas in French Guiana. Each subsite is covered by one data file. The Z2 data area covers a spirotropis forest type area, the Z3 data area covers a riparian vegetation with Avicenia, and the Z4 data area covers a swamp forest.

  • The aerial laser scanning (ALS) dataset, acquired in 2007, covers the research area in the Nouragues reserve. Ground echoes are available as well as a digital terrain model (DTM), a digital surface model (DSM), and a digital canopy model (DCM) with a 1 meter resolution.

  • The aerial laser scanning (ALS) dataset acquired on 24 September 2014 covers eastern and western side of Montagne Trinité. Data acquired in the framework of DynForDiv project. Z1 ( East side of the montain); point density: all returns 17.83 last only 10.62 (per meter square) Z2 ( West part of the moutain); point density: all returns 18.97 last only 10.61 (per meter square)

  • The aerial laser scanning (ALS) dataset acquired on 24 September 2014 covers three ares of Montagne Plomb. Z1 (North Eastern part, north of crique Plomb); point density: all returns 19.30 last only 10.62 (per meter square) Z2 (central part, Eastern part of the mountain); point density: all returns 16.80 last only 10.16 (per meter square) Z3 (most western part, western side of the mountain) ; point density: all returns 17.08 last only 10.48 (per square units) Lidar Riegl LMS Q560 onboard a plane operated by Altoa, swath angle +/-20deg

  • The aerial laser scanning (ALS) dataset, acquired in 2004, covers three plots of Counami site in French Guiana. The laser recorded last reflected pulse. Ground points data where not delivered by ALTOA.

  • The aerial laser scanning (ALS) dataset, acquired on 11 September 2009, covers the experimental station Paracou in French Guiana. More precisely, the dataset covers 9 plots totally (Paracou 4, Paracou 5, Paracou 7, Paracou 8, Paracou 9 - Paracou 12, and Paracou 14) and 4 plots partly (Paracou 3, Paracou 6, Paracou 13, and Paracou 15). The area includes logged-over and unlogged forest, various forest heights and Pinot palm swamp forest .

  • 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. <br /> October 27 2025 version

  • The aerial laser scanning (ALS) dataset acquired on 26th September 2011 covers part of the Paracou experimental station in French Guiana. Plots entirely covered include Paracou 4, 5, 7, 8, 9, 10, 11, 12, and 14. Plots 3, 6, 13, and 15 are partially covered by the data. The area includes both natural unlogged forest and logged over forest.

  • The airborne data comprises laser elevation data acquired during an airborne geophysical survey over French Guiana in 1996. The study area, located along the coast in the south of Cayenne in French Guiana, measures 45 km x 55 km. The area is characterized by virgin forest and savannah. Most of the area is flat or slightly undulating, with elevation ranging from 0 to about 400 m above sea level. (e.g. Kaw mountain).
