摘要

本文介绍了保加利亚境内2009-2010年四个全球土地覆盖数据集(GlobeLand30、GlobCover、森林/非森林地图、树冠覆盖)的验证，这是地球观测小组(GEO)领导的一项任务的一部分。提出了一种将GIS处理能力、各种数据和基于专家知识的可视化解译方法相结合的综合验证方法。它旨在成为一种有效、节省时间的方法，允许在一个环境中验证多个数据集。所有验证数据集的结果以向量格式呈现，并带有结构化属性数据。分析结果表明，Tree canopy cover的精度最高(96.1%)，glocover 2009的精度最低(51.0%)，其他产品的精度也相当高，约为80.0%。

Integrated method for global land cover products' validation on the example of Bulgaria

The article presents the validation of four global land cover datasets for 2009–2010 (GlobeLand30, GlobCover, Forest/Non-forest map, Tree canopy cover) for the territory of Bulgaria as a part of a task led by the Group on Earth Observation (GEO). An integrated method for validation, combining the GIS processing capabilities, various data and the expert knowledge-based method of visual interpretation was developed. It aims to be an effective, time-saving approach, allowing validation of several datasets in one environment. The results are presented in vector format with structured attribute data for all validated datasets. The analysis reveals that the highest accuracy is observed for Tree canopy cover (96.1%), the lowest for GlobCover 2009 (51.0%), and the other products’ accuracy is considerably high, about 80.0%.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
