More Information
Summary:GlobeLand30 update data is one of the important products of the Construction Maintenance and Update of Geographic Information Resources Project (hereinafter referred to as the Update Project). It provides important basic information for national geographical conditions monitoring, eco-environmental assessment and global geographic information integrated services. Different from the land cover classification data in National Geoinformation Surveying and Monitoring Project, GlobeLand30 update data is a completely new type of scientific research outcomes with new setup of resolution, its data format and data structure are newly set according to the requirements of the Update Project. Therefore, current inspecting methods are of limitations and incompatibility and cannot be firmly reasonable for inspecting the accuracy of GlobeLand30 update data. Combining with the practice of quality control for the Update Project, this paper proposes a set of methods and processes for the quality inspection of the GlobeLand30 update data. It also summarizes the key points of its inspection and analyses the common errors found in the actual inspection practice of the Update Project from 2017 to 2018. It can provide a certain technical reference for the quality control and quality improvement of GlobeLand30 update data in the Update Project.
