Integration of historical maps into GIS

Summary/Abstract: Historical maps are precious materials, which show spatial distribution of land use,vegetation, river patterns, and so on at the time the maps were produced. They are used forthe reconstruction of past environments or for comparisons in time analyses. However theimprecision of the historical maps, in the geometrical sense, makes the task of the comparisonvery difficult. This drawback brings us to the idea of incorporating the historical maps intoGIS, after geometrical transformation of the maps. It makes possible comparing and overlayingmultiple maps from different time periods. Furthermore it gives map-scales to historical mapsand enables broader range of quantitative considerations. This greatly increases the value ofarchival maps as information source.The paper outlines the procedure of incorporating old maps into GIS and some results ofthe transformation of early maps.
