ABSTRACT - The Second Military Survey of the Habsburg Empire was carried out in Transylvania around 1860-1872. The survey had no geodetic basis; therefore the maps lacked a projection system. To rectify them with the current maps can be done only by using some landmarks. The study presents a method for rectifying these maps, the precision of the rectification being enough for GIS and cartographic purposes thus providing a useful instrument for the spatial analysis of the natural and anthropic environment of the 19th century Transylvania.
