The Integrated Query System of Digital Archives of Maps

This is a service built by the GIS Center, RCHSS, Academia Sinica under the project of ‘Digital Archive of Maps and Remote Sensing Imagery’ ( This is a cross-database query system that contains a large volume of historical maps that record the natural and artificial landscapes of various periods. For this reason, these maps are the best annotations for the peoples, places, and things of a particular period, while reflecting upon the local cultural records. Maps of a single place from different periods, together, paint a wholesome picture of the environmental, social, and cultural transitions, whereas maps from a single period of different places show distinct features of the environmental surroundings and developmental differences. Few people realize the value of these data, and as these historical data age, they become susceptible to damage. To compound, the lack of a systematic management and preservation method has caused inconvenience in query and application. The GIS Center, RCHSS, Academia Sinica, therefore, has collected all kinds of maps of Taiwan and China, digitizing them, thus preserving. Integrated with distributed environment of time and space, the system provides all kinds of information application and services. The integrated query allows users to search for thematic maps under the keep of the 12 databases kept by different archival units, consequently resulting in a more efficient method for finding the necessary images.
