空间数据质量与交通应用

空间数据质量在不同的应用领域有不同的特征,在一种应用中适用的数据不一定适用于另外一种应用。位置数据在交通领域的应用非常广泛,包括交通事故分析、交通需求量建模、基础设施管理、交通政策分析、商用车辆使用、交通线路使用及智能化交通运输系统,且有些应用对质量问题更为敏感。因此,建议空间数据质量报告中应附带所有空间数据的转换或使用。如果不附带属性数据,那么空间数据对交通应用的意义将很小或几乎没有。

Spatial Data Quality and Its Application to Transportation

Spatial data quality has different characteristics depending on the application in different fields.The data that are appropriate for one application may not fit for another application.Positional data are used for a wide range of transportation applications including accident analysis,transportation demand modeling,infrastructure management,transportation policy analysis,commercial vehicle operations,transit operations,and intelligent transportation systems.Some applications are more sensitive to quality than the others.It is recommended that the statements of spatial data quality should accompany the use or transfer of all spatial data.Spatial data has little or no value for the application to transportation without any attached attribute data.
