Large-scale Topographic Maps (LST-Maps) play an important role in China, so their quality is of great importance. In order to guarantee the quality of the survey and mapping achievements, China has been implementing a supervision and inspection system. There are relatively big differences in the content, mode of production and demands for application of the LST-Maps all over the country, making it difficult for current informatization level of supervision and traditional methods of quality control to become fair and efficient. The existing operational mode, sampling means, and technical standards of inspection applied in supervision are not entirely suitable for the needs in quality supervision and inspection of LST-Maps. In face of the abovementioned contradictions and problems, the research has combined the requirements of quality supervision and spot checks of all levels. Various achievements such as an index system, technical means, inspection procedures and a software platform have been created, and they are widely used in the quality supervision and spot checks of national and provincial LST-Maps over the past three years.
