New GIAP <\/a>research using Deep Learning to extract archaeological information from collections of maps produced during the European colonization of South Asia and Levant.<\/h6>\n

New research published this January in\u00a0Archaeological Prospection<\/a><\/em>\u00a0presents the results of how archaeological information can be extracted from historical maps using deep learning. The paper demonstrates the potential of this technique for large-scale analysis and showcases its limitations and challenges.<\/p>\n

The paper demonstrates the potential of this technique for large-scale analysis and showcases its limitations and challenges.<\/p>\n<\/div>\n<\/div>\n

Colonial powers undertook massive programmes of systematic mapping of their possessions for military and economic control purposes. Although the historical value of these maps is well known by archaeologists and historians, exhaustive archival work is needed to use the data they contain, including the thousands of potential locations of archaeological sites that can be inferred from those maps.<\/p>\n

This research provides a new tool to facilitate this work and render it accessible to the research community. It explores collections of maps produced by the Survey of India during the British dominion over modern India and Pakistan, and by the French authorities during the control of modern Syria.<\/p>\n

\n

Using deep learning it is now possible to extract information about 1) mound sites, unintentionally represented as topographical anomalies by the surveyors; 2) sites purposely reported and represented as conventional signs; and 3) toponyms that might refer to archaeological sites.<\/p>\n<\/div>\n

This technique provides the potential of exploring large series of hundreds of maps in a quick and reliable way. That can be an invaluable tool for the management of cultural heritage and the development of historical and archaeological research<\/strong>.<\/p>\n
