  • 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 October 2004, covers five plots of Crique Plomb and Montagne Plomb area in French Guiana. In this area. the forest presents contrasting and diversified characteristics : high forest, forest grown on ferricrust, and superficial saprolit with high density of stem per hectare. 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 between 8 and 9 April 2009, covers five plots of Crique Plomb and Montagne Plomb area in French Guiana. In this area. the forest presents contrasting and diversified characteristics: high forest, forest grown on ferricrust, and superficial saprolit with high density of stem per hectare. Ground echoes are available as well as a digital terrain model (DTM), a digital surface model (DSM), a digital canopy model (DCM) with a 1 meter resolution and a triangulated irregular network (TIN) digital terrain model with a precision of 5 meters.

  • The image covers the experimental sites Counami, Paracou, Piste Saint Elie, Crique Plomb and Montagne Plomb in French Guiana.

  • Guyafor is a network of permanent forest plots installed in French Guiana. The site of Montagne Plomb covers a 6ha area, managed by CIRAD. 3249 trees are being followed. Three campaignes of inventories have been made in 2005, 2008 and 2010.

  • The image covers the experimental sites Counami, Paracou, Piste Saint Elii, Crique Passoura, Crique Plomb and Montagne Plomb in French Guiana.

  • Guyadiv is a network of permanent forest plots installed over the years in French Guiana. In these plots, all trees above 10 cm dbh are identified, measured and mapped. Several plots are part of permanent research stations (Paracou, Nouragues, Piste Saint Elie). The diversity of arborescent species flora is studied (floristic list). This flora diversity depends on the forest vegetation (architecture, structure, biomass, dynamic in the long term, dynamic after perturbation and biogeography) which is also studied. The contribution of flora diversity to forest vegetation (carbon cycle issue...) is another topic approach in the studies. Analyses are conducted at different spatial scales (local - intra site, regional, subcontinental via ATDN network) and temporal scale (impact of logging, impact of old settlements : COUAC project). We only have the point coordinates and not the precise demarcation for most of the sample plots. In order to calculate the bounding box for these plots, we have expanded the point location between 100 and 600 meters in each direction. Information specific of each site (Paracou, Montagne Plomb, Crique Plomb, Piste Saint Elie, Counami...) is available. Please refer to the attached metadata sheets. This network relies greatly on the IRD Herbier de Guyane (CAY) and its network of international specialists.

  • Guyadiv is a network of permanent forest plots installed in French Guiana. The Guyadiv plan in Crique Plomb and Montagne Plomb sites implements several types of plots and sampling methods: A first group of plots belongs to the Paget's plan, initiated in 1998. These 30x40m-plots are used for floristic and structural inventories.Then, 8 1ha-plots are used for floristic inventories concerning trees with DBH>10cm, since 2002 (campaigns in 2002, 2004 and 2005). These plots are located on greatly contrasted forest facies (high-density forest on thinned soils, forest on dismantled ferricrust, forest on deap DVL soils). The third type of sampling method is a "cluster points" (points-grappe) plan for floristic linear inventories. 18 points have been carried out, that is to say almost 8500m or 10ha of statements (ca. 5500 trees). 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 600 meters in each direction.

  • Guyafor is a network of permanent forest plots installed in French Guiana. The Guyafor Database compiles coordinates of the 11 sites (Paracou, Bafog, Organabo, Risquetout, Montagne Tortue, Saut Lavilette, Acarouany (Javouhey), Montagne Plomb, Tibourou, Nouragues, Laussat) and their subdivisions of the guianese permanent plots network. Each site contains georeferenced trees, botanically identified and regularly measured (diameter) for varying periods, depending to the site.
