Shaanxi Province 1:1,000,000 Land Resource Map Database, which is cropped from the National 1:1,000,000 Land Resource Map Database of China. The national database is composed of raster images scanned from original paper maps, vector data compatible with both Lambert projection and Geographic projection, projection parameter files and technical documentation. The data volume of the national database is approximately 2 GB for raster images and 230 MB for vector data. The vector data is organized in map sheets, with sheet numbers adhering to international standards, totaling 63 sheets. This dataset is primarily applicable to land resource research and other related fields. Its target users include scientific researchers engaged in land resource-related studies, as well as government decision-making departments. The data collection period spanned from 1950 to 2000. The spatial scope and projection method of the dataset adopt Lambert projection. The academic discipline of this dataset falls within the scope of geography. The total data volume is approximately 1616 KB, and the dataset is updated irregularly.
