TīmeklisToday, scientists use NASA satellites to map leaf area index — images processed to show how much of an area is covered by leaves. For example, a leaf area index of one means the area is entirely covered by one layer of leaves. Knowing the total area covered by leaves helps scientists monitor how much water, carbon, and energy the … Tīmeklis2024. gada 20. nov. · All these datasets are too small to train neural networks, and unrealistic as they are either synthetically generated or captured in controlled lab environments.
