Abstract

The invention discloses a rice planting distribution extraction method based on wind cloud satellite data. The method comprises the following steps: acquiring remote sensing indexes of rice in different phenological periods in a research area based on wind cloud satellite image data, wherein the remote sensing indexes comprise a normalized water body index, a normalized vegetation index, a ratio vegetation index and a difference value between the normalized water body index and the normalized vegetation index; according to a threshold value of a difference value between the normalized water body index and the normalized vegetation index, extracting a rice potential planting distribution area; performing pixel elimination on the wind cloud satellite image data of the potential rice planting distribution area according to thresholds of the normalized water body index, the normalized vegetation index and the ratio vegetation index of the rice in different phenological periods in the research area to obtain an actual rice planting distribution map in the research area; and obtaining the rice planting area of the research region based on the actual rice planting distribution diagram of the research region. The technical blank of rice planting distribution information extraction based on wind cloud satellite data is filled, and high-precision extraction of rice planting distribution is realized.

Description

Technical field [0001] The present application relates to the field of raw planting distribution remote sensing extraction, and in particular, there is a method of extracting rice planting distribution based on wind and satellite data. Background technique [0002] Rice is the second largest crop type in China, and timely and accurately grasp the planting area and spatial distribution of rice, it is important in realistic meaning of macro-guided rice production, reasonable development of agricultural policies. Due to the advantages of satellite remote sensing technology, it has the advantages of timely, timely economical, efficient, and has become the main technical means of obtaining information on rice area spatial distribution, and is mostly based on Landsat, MODIS and other foreign remote sensing data sources. In recent years, my country's satellite remote sensing technology has developed rapidly, and many independent research and development satellites have been launched, bu...
