[Abstract]:The field of land resources is one of the industries that used remote sensing technology and formed scale application earlier in China. Satellite remote sensing technology, with its rapid, objective and macroscopic advantages, has become an indispensable technical means for land resources investigation, monitoring and evaluation. China has basically established a modern remote sensing monitoring system for land resources supported by remote sensing technology. Resource-02C satellite (hereinafter referred to as "02C satellite") is the first high-resolution operational satellite in China. It was successfully launched on December 22, 2011. It makes full use of the high-resolution remote sensing data obtained by the 02C satellite to carry out image processing. The research on the technology of extracting thematic information on land use will promote the application of 02C satellite in the field of land resources survey and monitoring. It is of great significance to enrich the remote sensing application system of land resources in China. In view of the characteristics of high resolution, panchromatic and multispectral data of Resource-02C satellite, data quality evaluation and image preprocessing are carried out in this paper. Classification of land use by remote sensing. The main work and achievements are as follows: 1) Image quality evaluation: from the aspects of internal geometric accuracy, band registration accuracy, signal-to-noise ratio, data coverage ability, mapping scale, interpretation ability, etc. The land application ability of 02C satellite data is evaluated. The evaluation results show that the geometric distortion of 02C satellite data is relatively large and HR data can satisfy the precision requirement of mapping on a scale of 1: 25,000. In this paper, the geometric correction and image registration technology of the 10m multispectral data of 2. 36m high resolution 5 m panchromatic data of resource-1 02C satellite are compared and studied. The experimental results show that the matching accuracy of geometric correction based on small spline model is high. The classification ability of 02C satellite data is evaluated in terms of texture separability and integrative element separability, and compared with SPOT-5 IKONOS data. The experimental results show that the accuracy of typical ground class recognition of 02C satellite multispectral data is higher than that of SPOT-5KIKONOS data. It can basically meet the requirements of land use remote sensing classification application. This paper objectively evaluates the data quality through the systematic research on the quality evaluation of 02C satellite data, the research of image preprocessing technology and the application evaluation of land use remote sensing classification. A feasible method of image preprocessing is put forward, and the application precision of land use remote sensing classification is comprehensively analyzed. The research results can provide a technical reference for land use remote sensing monitoring based on 02C satellite. And lay the foundation for fully excavating the value of 02C satellite application.
