We also made and are making strong cooperation with the Croatian National Archive. After the first successes of our website, we were able to establish cooperation to more European archives, libraries and mapping authorities. Now the cooperation is live with also with the Royal Library of Belgium, National Library of Scotland, the National Archives of Finland (Kansallisarkisto) and the Norwegian Mapping Authority (Kartverket). Scientific achievements In the last years, we made interesting achievements in defining and applying geodetic datum and map projection parameters for some new historical map products. We published the Cassini map of France, based on the result of Tímár et al. (2014a), the Walachian part of the Old Romania after Tímár et al. (2014b), the Habsburg maps of Italy (Tímár et al., 2017a) and the Norwegian Rektangelkart series (Tímár et al., 2017b). However, combining the method of Molnár & Tímár (2015) to estimate the bestfitting Cassini projection parameters, our applications were rather shifting to usage of virtual mosaics and their georeferenced, sometimes completed by correction grids (GSB; application description by Molnár et al., 2014). The Habsburg maps of Italy was the test area of this, and finally the whole map collection of southern Germany, Alsace and Sicily was geo-referred without knowing and even without estimating the appropriate GIS parameters, based on just virtual mosaics, ground control points and their resulted GSB. A new feature in our city map series (Fig. 2) is the application of historical airphoto orthorectification (Molnár et al., 2017). We present the WWII wartime Budapest, before the severe siege, mostly intact, only with some bombing damages in the southern part with this method.
