THE USE OF OPEN SOURCE SOLUTIONS IN THE PROCESS OF GEOREFERENCING THE HISTORICAL MAPS PUBLISHEDS. DOROBANTU1*, C. NEGRESCU1 firstname.lastname@example.org
Abstract. The present paper presents the aspects of the georeferencing concept, especially applied in the georeferencing of historical maps. The topographic map had a culminating evolution since 18th century, from a military perspective. The Banat and Transylvania territories, being under an Austro-Hungarian domination, appeared as the first topographic maps, at the order of Maria Theresa, in 1704. Due to new computing technologies, the study of metrical proprieties on early maps grew in time, the historical map having an important role in nowadays surveying. This is possible with the help of the georeferencing process, which refers to a process of bringing a cartographic image in a spatial location, defined in relation with a known system of coordinates. In this paper, a vivid example of this concept has been addressed, namely, the georeferencing historical map of the Timisoara citadel and its surroundings, a map dating from 1864-1865. An open-source georeferencing software was used to accomplish this task, an application that offers the possibility to visualise dates, to edit and to analyse them. The importance of this paper results from the difference between the historical map presented and the actual emplacement of the citadel of Timisoara in the past. The old settlements and Bega canal bed can be seen using importing and overlapping in Google Earth.
