Crop survey by farmland: using satellite and aerial remote sensing to help estimate agricultural statistics
Using satellite and aerial remote sensing to help estimate agricultural statistics
Build up the spatial sampling frame by using the data from land use surveys and agricultural census. Then update the sampling frame by satellite and aerial remote sensing. With the samples selected by spatial sampling method, we estimate the crop planting area and output every season.
Project Objective:
Pilot intended to go to production to replace existing data
Project Outcomes:
Gradually carry forward the crops survey by farmland instead of the traditional method used in China's major grain-producing areas to improve the accuracy, timeliness and consistency of the data to ensure data quality.
