摘要
2018年度全球地理信息资源建设项目10 m地表覆盖数据的生产是我国开展全球范围内高精度地表覆盖生产的第一年,对比第一次地理国情普查地表覆盖数据生产相关技术要求,全球项目对于地表覆盖数据生产的要求分类的地类相对较少,地类综合程度高,地类边界精度要求相对低,适宜研究自动解译分类方法辅助生产作业。
The production of 10 m surface coverage data in the global geographic information resources construction project in 2018 is the first year for China to carry out high-precision surface coverage production worldwide.Compared with the related technical requirements of the first geographic national survey,the requirements of the global project for the production of surface coverage data are relatively small,and the comprehensive degree of land types is high.The accuracy requirement of class boundary is relatively low,so it is suitable to study automatic interpretation classification method to assist production operations.
