Map interface has been long serving as the major platform for GIS users to visually inspect the phenomena of reality. One distinct and improving feature of the internet GIS technology is the easier sharing of geospatial data from distributed georesources. Although this development enables a more dynamic and flexible data integration at clients' applications, the heterogeneous nature of different georesources, nonetheless, becomes an impediment to the correct interpretation towards the illustrated content of the map interface. Based on the standardized geospatial metadata and the formalization of cartographic knowledge, this paper proposed a visualized mechanism for data quality in the GIS-based map interface. The standardized metadata framework allows the quality status of every individual dataset to be consistently parsed and analyzed. By incorporating visualized design for data completeness, logical consistency, temporal difference and positional accuracy, the map interface can suffice both the needs of data visualization and quality evaluation. As the number of accessible geospatial information continues to grow in the future, such an intelligent map interface is absolutely a mandatory feature for any applications that wish to take advantages of the abundant internet georesources.
