BEIJING, Nov. 20 (Xinhua) -- China has achieved a 30-meter-resolution Global Forest Cover Map (GFCM) of 2018 for forest management, according to the Aerospace Information Research Institute of the Chinese Academy of Sciences on Wednesday. The researchers constructed a high-resolution forest and ...
Using a model tree ensemble method (MTE) to regress the seven reflectance bands of EOS-Terra-MODIS satellite data against country level forest biomass carbon density (BCD) of 2001–2005 provided by United Nations’s Forest Resource Assessment (FRA), we developed a global map of forest BCD at...
After removing the non-forest areas, the ESA CCI biomass map presented zones in the Iberian Peninsula with no biomass while the Copernicus Forest Type and Tree Cover maps indicate the presence of forest with substantial tree cover (up to 50%). When applying a bias-correction approach, the pre...
Forest thematic mapping products, such as global 30 m spatial distribution of forest cover in 2020 (GFC30_2020) [15], have also been developed, alongside continuously updated forest products like Hansen Global Forest Change (Hansen GFC) [16] and the Global PALSAR-2 Forest/Non-Forest map (...
b, Global 30-m map of aboveground live woody biomass density in the year 2000. Extended Data Fig. 2 Results of sensitivity analysis when the source of tree cover loss data used in the forest GHG flux model is changed from the 30-m tree cover loss product of Hansen et al.15 in the ...
, as well as map the land cover for other classes: Rhizophora mangle, water and mud (see Figure 1). The input data were a set of orthomosaics and DSMs created from images captured with consumer-grade UASs in three mangrove forest stands located in the Utría National Park on the ...
Tropical forests presently cover about 1.84 billion hectares or about 12 percent of Earth's land surface (3.6% of Earth's surface). The world's largest rainforest is the Amazon rainforest Brazil has the largest extent of rainforest cover, including nearly two-thirds of the Amazon. ...
Airborne data of the study site in the New Forest, UK included colour aerial photographs, LIDAR (Light Detection And Ranging) and ATM (Airborne Thematic Mapper) imagery. A DEM (Digital Elevation Model) was generated from LIDAR data and then subtracted from the original LIDAR image to create a...
During this process, a forest mask based on the SLEEK land cover map for the year 2016 (Kenduiywo et al., 2020) is used to filter out any non-forest locations. Fig. 4 illustrates the individual processing steps with real examples. A second program then takes the Pyeo-produced change ...
Surveys of India (SoI) topographical sheet as well map provided by West Bengal State Forest Division were used to delineation of Protected Forest (PF) Boundary as the basement of the work. Region cover by BFD and its immediate surrounding area has been sensibly clipped based on area of ...
