Qiangu Irrigation Area Rice Leaf Coverage Distribution Map

The dataset comprises 135 field-level canopy measurement sampling points gathered from rice fields within the Qiangu Irrigation Area in August 2023. The sampling distribution covers various irrigation zones, soil fertility levels, cropping systems, and rice varieties across the irrigation area, encompassing both contiguous large-scale fields and scattered individual plots, thereby ensuring broad regional representativeness.

Rice leaf canopy cover (unit:%) was determined at each sampling point using a canopy analyzer combined with UAV aerial photography verification methodology; this value is defined as the percentage of the vertical projected leaf area relative to the total plot area, with a numerical range between 0% and 100%. Based on the field-measured data from each sampling point and multi-temporal remote sensing variables, a Random Forest (RF) model was employed for the spatial inversion and prediction of rice leaf canopy cover, resulting in a leaf canopy cover raster map covering the entire irrigation area (resolution: 10 m), with a total file size of approximately 12.68 GB.
