A dataset of UAV aboveground biomass of typical grassland in Tajikistan
Central Asia boasts the largest contiguous grassland in the world.Tajikistan,as a typical representative of the five Central Asian countries,holds significant research value for studying the status of its grassland vegetation.In this research,we conducted a UAV survey of grassland resources at five typical sites in Tajikistan,adhering strictly to standard specifications for data sampling.Using a fixed-wing UAV equipped with optical cameras,we captured both multi-spectral and RGB images during clear weather conditions.In the following of the aerial photography,we collected aboveground biomass data by placing quadrants on the ground and cutting the vegetation.The ground-measured aboveground biomass and UAV data products were then input into a generalized additive model to build an aboveground biomass inversion model.Cross validation has been used to ensure the quality of the model,resulting in high-precision biomass modeling.Subsequently,the UAV aboveground biomass product can be produced at a resolution of 1m.This dataset can be applied to the analysis of the aboveground biomass in Central Asia's grasslands at local scale.Besides,it can also be used to validate satellite products,contributing to address scale biases between traditional measurements and satellite observations.
