摘要:
本文针对全球30米分辨率地表覆盖遥感制图这一世界性难题,提出了以多源影像最优化处理、参考资料服务化整合、覆盖类型精细化提取、产品质量多元化检核为主线的总体研究思路,研发了影像几何与辐射重建、异质异构服务化集成、对象化分层分类、知识化检核处理等主体技术方法;用于制定了相应数据产品规范、生产技术规范,研发了多项生产型软件,用于研制了2000和2010两个基准年的全球)30米地表覆盖数据产品,将空间分辨率提高了1个数量级。
Abstract:
Global Land Cover (GLC) characterization and monitoring at fine resolution is a key task and big challenge for both earth observation and geomatics societies in the world. Recently the first operational 30-m GLC mapping project has been completed by China. It is based on the optimum selection and processing of Landsat-like satellite imagery for full global coverage, service-oriented integration of all available reference data and auxiliary information, objected-based precise land cover characterization, and knowledge-based data quality controlling. The key techniques developed include the multi-type imagery geometric processing and radiometric reconstruction, integration of heterogeneous data and external services, object-based thematic-layer classification, and knowledge-based spatio-temporal consistency verification. The technical guidelines and software tools have been further developed for supporting the operational 30-m GLC mapping of the years 2000 and 2010.
