The worldwide variation in vegetation height is fundamental to the global carbon cycle and central to the functioning of ecosystems and their biodiversity. Geospatially explicit and, ideally, highly resolved information is required to manage terrestrial
Using a deep learning approach, the authors outline a global canopy height map at 10-m resolution combining publicly available optical satellite images and space-borne LiDAR and show that only 5% of the global landmass is covered by trees taller than 30m....

The paper also discusses about the influence of urban land scape features on air quality, accuracy of emission inventory and model validation methods. The present review provides a vantage point to the researchers in the emerging field of high resolution urban air quality modeling for devising the...
11. Resolution and computing time The influence of image resolution was evaluated at different steps of the FIELDimageR pipeline. For this propose, the resolution of image EX1_RGB_HighResolution.tif Download was reduced using the function raster::aggregate in order to simulate different flown altitud...
This paper presents a survey of image processing techniques proposed in the literature for extracting key cereal crop growth metrics from high spatial resolution, typically proximal images. The descriptive crop growth metrics considered are: crop canopy cover, above ground biomass, leaf area index (inc...

In this study the potential of ultra-high spatially resolved UAV image data was investigated to quantify lodging percentage, lodging development and lodging severity of barley using Structure from Motion techniques. The term lodging is defined as the permanent displacement of a plant from the upright...
