Integration of multiscale spatial data for forest types and biomass mapping in Amapá and French Guianne
Integration of multiscale spatial data for forest types and biomass mapping in Amapá and French Guianne
The Amapá state has extensive forests and savannas, which are important carbon stocks being negatively affected due to agricultural, forestry and industrial activities. Thus the project aims to develop a methodology applicable to the entire State of Amapá, aiming to reach all types of existing vegetation, being the basis for estimates of forest biomass and the quantification of carbon stocks, in addition to enabling the monitoring of changes caused on biomass due to the economic activities developed in these forest and savanna areas. The challenge is to take advantage of multiple sources of multiscale from remote sensing data and extrapolate to field inventory data. This project is built on the results of Embrapa’s BIOFLOR and GUIAMAFLOR projects, involving the teams that are proposing and carrying out a survey of the biomass and carbon stocks in the states of Amapá and Amazonas, and in French Guiana, as well as in other regions of tropical forests. In addition to being aligned with the accomplishment of the cartographic base of the State of Amapá. The proposed idea consists of four stages: the identification and mapping of geomorphological units (relief, hydrography, soil, forests); the study within these gradient units and changes in the canopy of forests and savannas through optical satellite images with high spatial resolution; the installation of permanent sampling plots for enhanced field measurements through altimetric readings by LiDAR (transported by drones); and the completion and implementation of allometric equations specific to the forests of the State of Amapá. These integrated steps will allow an assessment of errors in the extrapolation of field data to units on the map. In addition to estimating stocks of biomass and carbon, it will allow the identification of forest types in maps related to geomorphological units and may serve as a basis for zoning the territory and the identification of conservation priorities and sustainable use of forest resources.
