#EvergreenBroad-leavedForest ( #EBLF ) is climax vegetation in East China, and Jiangxi Province is located at the center of EBLF. In this study, Yizhen Liu et al. provided a high-level #ClassificationFramework for EBLF in #Jiangxi and exploring the roles of #Topographic and #Climatic factors in driving their distributions.

“HIGHLIGHTS:
• [They] evaluated the impacts of topographic correction on forest mapping in the mountains.
• The enhanced C-correction and the physical model reduced topographic effects.
• The corrected Landsat imagery time series resulted in higher accuracy.
• Terrain information improved classification but not as much as topographic correction.
• [They] recommend using topographic correction for forest cover mapping..."

“To respond to growing needs for high-quality elevation data, the goal of 3DEP is to complete acquisition of nationwide lidar (IfSAR in AK) to provide the first-ever national baseline of consistent high-resolution topographic elevation data – both bare earth and 3D point clouds. This dataset provides the raw 3D point clouds in the Cloud Optimized Point Cloud format, and various derived products as Cloud Optimized GeoTIFFs…”
