基于志愿者认知习惯的全球地表覆盖数据标报
|
摘要
随着移动互联网和Web2.0技术的发展,地表覆盖变化更新的形式越来越多样化、大众化,在利用志愿者地理信息作为专业测绘部门更新数据源的研究中,基于志愿者行为习惯的数据采集研究较少。本文针对目前缺乏志愿者标报行为习惯的问题,采用问卷、实地标报等调查形式,通过分析志愿者对地表覆盖变化情况的认知过程、标报变化地物的行为习惯,提出了基于志愿者认知、标报习惯与便利性的地表覆盖标报方法,以指导志愿者规范化标报地表覆盖变化信息。
With the development of mobile internet and Web2.0 technology. The updated form of land cover change is becoming more and more diversified and popular. Based on the behavior of volunteers is less in data collection,which is a professional survey department in the study of using volunteered geographic information to update the data source.Questionnaires and field reports are used in this study of cognitive habits,with the aiming of acquiring more knowledge from marking and reporting based on cognition and habits of volunteers. By analyzing volunteers' cognition of the change of surface cover and features of habits,this article proposes a land cover labeling method based on volunteer's cognition,guiding standardized behaviors on marking and reporting from volunteers for different information.
