Much research has been done trying to accurately convert the TOA measurements to surface-reflectance measurements.â©, The challenge has been the availability of accurate atmospheric measurements at appropriate scale, ensuring imagery can be normalized. Observing soil types and conditions before, during and after a crop season is important for managing crop health.

Figure 4RESULTS . Ground Station WorldView-3 addresses this problem by becoming the first commercial imaging satellite with an atmospheric sensor as part of its payload.â©, During image capture, the WorldView-3 atmospheric sensor is designed to detect the presence of clouds, aerosols and water vapour at 30-meter resolution, thereby measuring the exact atmospheric conditions corresponding to every recorded image. +, Satellite images show whales being held captive in Russia’s Srednyaya Bay amongst international outcries for the animals’ release. â©, One of the agricultural community’s best management practices relates to how much post-harvest crop residue is left on a field. Crop stresses change the green chlorophyll content of the leaves and replace them with carotenoids that have yellow and red colours. 286 0 obj <> endobj

WV-3 image . In addition, SWIR bands are used to assess crop moisture, as another health indicator. It is important to take corrective action early in the growing season by understanding crop conditions. Fast and effective detection is key to protecting infrastructure and ensuring communities’ safety. Yellow, red edge and the two near-infrared bands are sensitive to changes in the green chlorophyll and expose the carotenoids during stress.
