摘要: 简述了过去研究空间数据不确定性的方法及其缺点,提出了一个基于地理数据场模型和模糊集合论的生成ε-误差带的新方法。某城郊的土地覆盖制图的实例证明了本文所提方法的理论性强、效率高,并且有助于今后对地理信息系统不确定性的理论问题展开系统的研究。

Abstract: This paper provides a review of research on uncertainties in geographical information systems(GISs).This is followed by a description of a new method for deriving X-error band models based on the concepts of fields and fuzzy sets.A case study on a suburban land cover mapping confirmed that the proposed method is both theoretically sound and empirically efficient.The new strategy adopted in this paper will be beneficial for further systematic research on GIS uncertainties.
