Land cover plays an important role in the study of ecological environment, natural resource management and sustainable development. When using the artificial visual interpretation method of surface coverage for information extraction, it is easily affected by regional characteristics, remote sensing image quality and other factors. Based on the analysis of the classification system and production method of land cover data, this paper puts forward the solution strategies of information extraction in hybrid area and weak texture image area, and provides some useful thinking for land cover information extraction.
