Accuracy assessments of the derived land cover maps were performed using a forest inventory map provided by the Saskatchewan Environment and Resource Management Forestry Branch Inventory Unit (SERMFBIU). The forest vegetation classification using seasonal optical indices (mNDVIs and 0), as derived ...
To explore the entire high resolution forest map, click the image above. Below we’ll take a closer look at some of the world’s green zones. Asia Home to the boreal forests of Russia, China’s broad-leaved forests, the mangrove forests of Indonesia, and the green belt along the mighty...
Using imagery of the Canadian boreal forest, we explored the ability of the Airborne Visible Infrared Imaging Spectrometer (AVIRIS) to map vegetation type by taking advantage of pigment and water absorption features. Two techniques were exploited. In the first classification routine, laboratory-acquired...
distributed in all vegetation categories in the region. The map uses airborne laser scanning (ALS) data calibrated by field forest inventories that are extrapolated to the region using a machine learning approach with inputs from Synthetic Aperture Radar (PALSAR), vegetation indices obtained from the...
temperate coniferous forests and (6) boreal forests/taiga, following the World Wildlife Fund’s ecoregions classification53. The relationship between forest loss and the probability of impact from forest loss as captured by agriculture and logging overall showed a significant positive correlation:PTh,...
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...
在仙境中,由于地形起伏更为明显,草地被设计成了大陆中西侧内,被森林环绕的平原与高原;而在瓦尔盖罗,虽然群落组成与结构不变,但“草地”在景观上被更改为了统一的北方针叶林(Boreal forest);个人觉得这两种处理都很不错。 仙境(左)和瓦尔盖罗(右)中的“Grassland”,图片来源:ark.fandom.com...

3.9. Map Projection and Tiling To enable time series analysis such as generalizing data, statistical mapping and analytical work, all data has to be projected to a common reference grid. Therefore, within the TIMELINE processing framework, a generic processor was developed for the projection of the...
Forest losses and gains are highly dynamic processes. Here, the authors present a forest fragmentation index to map distribution and temporal changes of forest fragments globally, revealing major trends and patterns during the first two decades of the 21st century. Jun Ma Jiawei Li Jiajia Liu Art...
