Abstract

The invention relates to a remote sensing charting method and device for karst rocky desertification, which effectively depicts and extracts information reflecting karst rocky desertification characteristics through remote sensing image data and thematic data so as to improve the recognition capability of a machine learning algorithm on each rocky desertification level. Meanwhile, the rocky desertification units are defined by adopting an object-oriented strategy, so that automatic drawing of the to-be-graded units of the karst rocky desertification is realized, and the rocky desertification drawing units are outlined. On the basis, karst rocky desertification mapping can be rapidly achieved through a small amount of sample data, the mapping precision and efficiency are improved, and meanwhile the advantages of being high in automation degree and transportability are achieved.

Description

technical field [0001] The invention relates to the technical field of geographic information images, in particular to a remote sensing mapping method and device for karst rocky desertification. Background technique [0002] As a special type of land desertification, karst rocky desertification is a major economic, ecological and environmental problem worldwide, threatening the sustainable development of society. Quickly and accurately mapping the spatial distribution of regional karst rocky desertification can effectively realize the dynamic monitoring of rocky desertification and assist in the formulation and effect evaluation of rocky desertification control measures. Remote sensing images have become an important source of large-scale spatial mapping of rocky desertification. Since the visual interpretation technology used in previous studies is time-consuming and laborious, it is of great significance to use automatic and semi-automatic recognition methods for high-prec...
