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： Acta geographica Slovenica publishes original research papers from all fields of geography and related disciplines, and provides a forum for discussing new aspects of theory, methods, issues, and research findings, especially in Central, Eastern and Southeastern Europe. The review accepts original research papers and review papers. Papers presenting new developments and innovative methods in geography are welcome. Submissions should address current research gaps and explore state-of-the-art issues. Research based on case studies should have the added value of transnational comparison and should be integrated into established or new theoretical and conceptual frameworks. The target readership is researchers, policymakers, students, and others who are studying or applying geography at various levels. Submissions are accepted in English or Slovenian.
