Rio de Oro partvidékéről kézzel készített osztrák-magyar térképrajzok

The buying of the Rio de Oro area from the side of The Austro-Hungarian Monarchy was an instructive and interesting episode in the relation question between Hungary and Western Sahara. The exhibition of the 3 pieces – so far unknown – hand drawn sketch maps is an important part of the information background. Reproducing the original maps is an essential add in the quest of this project as well as in revealing of the Spanish and Austrian negotiation process. The last mentioned task could be executed with GIS and results a compact, graphically expressive projection, which includes all three charts. This process conserves the character of the original sketches, besides it satisfies the accuracy requirements of the modern age. The other option in order to retrieve reference data that we attempt to reconstruct the coast of Rio de Oro around 1899. To achieve this goal more investigational resources and bigger scale maps of this age are needed. However we can state that with sufficient care the process mixing older and modern information could be an efficient way in reprography of maps from that age.
