Feasibility Study on Plot Proportion Estimation Method to Quickly Investigate Major Food Crop Planting
Based on the typicality of food crop planting,transportation convenience,crop growth and other conditions,a village in Xingren City is selected as the experimental area for rapid investigation of food crop planting,and the planting of main grain crops is investigated by using three methods:low-altitude aerial photogrammetry,automatic classification of satellite images based on interpretation samples,and plot proportion estimation.The advantages and disadvantages of these three methods are compared from the aspects of survey area,time,accuracy and informatization according to the experimental results.The feasibility of using the proportion estimation method to quickly investigate the planting of major food crops and the relevant imaging factors affecting the accuracy of the survey are verified.
