贵州省1：100万土地资源图数据库，裁剪自中国1：100万土地资源图数据库，全国数据库由栅格图（原始纸图扫描）、矢量数据（Lambert投影和Geographic投影）、投影参数文件和技术文档组成。数据量：栅格图约2G；矢量数据约230MB。矢量数据是分幅组织的，分幅编号采用国际标准，图幅数63幅。本数据集主要应用于土地资源研究等。服务对象包括从事土地资源相关研究的科技工作者使用，也适用于政府决策部门使用。数据收集时间为1950-2000年。数据的空间范围、投影方式Lanbert投影，数据的学科范围属于地理学范围，数据量合计约1616KB，不定期更新。

This dataset is the Guizhou Province 1:1,000,000 Land Resource Map Database, which is cropped from the China 1:1,000,000 Land Resource Map Database. The national database is composed of raster maps (scanned from original paper maps), vector data with Lambert projection and Geographic projection, projection parameter files, and technical documentation. The data volume stands at approximately 2 GB for raster maps and 230 MB for vector data. The vector data is organized into map sheets, with sheet numbers compliant with international standards, totaling 63 sheets. This dataset is primarily applied 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 was collected between 1950 and 2000. The spatial scope and projection method of the dataset adopt the Lambert projection. The disciplinary scope of this dataset falls within the field of geography, with a total data volume of approximately 1616 KB, and it is updated irregularly.
