Timeline collaging as an extension of map collaging using geo-referencing and time-referencing

Nowadays, there is an explosion of spatio-temporal data, such as big data of human movements and aerial photographs taken in time series. Interactive and dynamic visualization of such data play important roles in researching and applications in the fields of traffic controlling, education, storytelling and so on. On the other hand, besides of the “modern” digital data, there are also large amount of “traditional” analogue data in the forms of maps, books, photographs and so on. Such analogue materials are valuable for historical researches and education, but current spatio-temporal visualization systems are not good at dealing such analogue materials compared to their performances on digital data. This paper introduces our research on collaging analogue maps and timeline graphs through geo-references and time-references, to enrich the analogue materials with multimedia digital data, and enable user interactions and dynamic visualization of the enriched data on digital devices for researching, education and storytelling.
