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’ (http://gis.rchss.sinica.edu.tw/mapdap/). 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.

Taiwan Centurial Historical Map

This is a brand new system built with the accumulation of a large volume of Taiwan maps and integrated with GoogleMaps. Users are able to choose 2-3 images for overlay and the transparency of each of the images could be customized in order for a more visually effective comparison of the maps of different times. This allows a more wholesome grasp of the transitions throughout the century-old history of Taiwan.

Cultural Resources Geographic Information System


Cultural Resources Geographic Information System (CRGIS) takes geographical space as its core concept and incorporates Geographic Information System to compile tangible and intangible cultural resources and their spaces and attribute data. With various types of images, including historical maps, contemporary images (like Google satellite images) etc., the system offers a wholesome information platform which encompasses all forms of cultural resources, such as temples, historic sites, historic buildings, old trees, folk religious activities, etc, and allowing functions such as adding, editing, organizing, and data retrieving, in the form of image displays.


As of May, 2010, the database contains information on the following (numbers are approximate):

  • 11000 temples
  • 700 historic sites
  • 3400 old trees

Information on temples mainly come from records of the Ministry of the Interior and local cultural and historical workers (Kaohsiung) and field work. List of historic sites and buildings is provided by the Bureau of Cultural Heritage; list of old trees provided by the Endemic Species Institute of the Council of Agriculture. Comments and feedback to help us expand the content of the system are welcome.
