Due to the spatial data of land plots need to do examination of spatial and attribute, attribute inspection in the include attribute values to check for reproducibility, including the fields of different data types, according to the expansion and development needs, based on the basis development interface for Arcgis10.1 under the Ao component, the realiZation of the belongs to the field of duplicate values check and results display. In spatial data attribute inspection application range is larger.%由于土地地块空间数据需要做空间和属性的检查,属性检查中包括属性值重复性检查,涉及包括不同数据类型的字段,根据需求扩展开发后,基于Arcgis10.1下AO组件提供的基础开发接口,实现了属性字段重复值检查与结果显示,在空间数据属性检查中应用范围较大。
