Regional Biomass Mapping Mexico

General Area Description

The regional areas of Mexico are represented by the areas of Yucatan Peninsula and Central Mexico. The study areas include tropical and subtropical moist broadleaf forests, dry broadleaf and coniferous forests, and mangroves. The study area in central Mexico additionally includes deserts and xeric shrublands.

Regional Mapping Product  – Reference Year 2010

Spatial Data  ALOS PALSAR dual polarization (2009/10), Landsat 7 Surface Reflectance (2010±1), Landsat Percent Tree Cover, SRTM (2000)
Additional Data A forest probability layer was used to determine the modelling extent (see methods). Any land area with a forest probability below 1% has a value of 0 by default. The Land Use and Vegetation layer (LUV) developed by INEGI was used to assign NoData value to water bodies and 0 value to urban areas
Training Data Forest inventory dataset provided by the Comision Forestal Nacional of Mexico – CONAFOR
Algorithm This map shows aboveground woody biomass in Mexican forests. The map was generated by combining the probabilistic outputs from a Maximum Entropy (MaxEnt) algorithm. Field inventory plots (CONAFOR, INFyS) were used in combination with SAR (JAXA, ALOS PALSAR) and optical data (NASA, Landsat 7 ETM+), as well as a digital elevation model (NASA, SRTM).
