A topographic map series of Northern Transylvania was drawn in the 1940s. Georeferencing them needs information about their coordinate systems. These maps used two reference systems known as the Budapest and the Marosvásárhely Stereographic projections. The datum transformation parameters of the former had already been determined in previous studies, but they had to be adjusted slightly to use a common Ferro–Greenwich difference for both systems. Parameters of the Marosvásárhely system were only available as a Molodenskiy transformation determined with insufficient accuracy. In this study, we recalculate the Molodenskiy parameters with higher accuracy and determine six parameters from the usual 7-parameter Helmert (aka. Burša–Wolf) transformation. The ideas given in this paper can be useful in other similar cases when the information about base point coordinates on the old system is very limited: We had access only to the ellipsoidal coordinates of the origin and the projected coordinates of one single point. The accuracy of the resulting transformation was evaluated by aligning the old map sheets with recent base maps.

Automatic labelling is a lacking feature in the popular client-side web mapping library, Leaflet. Although there exist various workarounds and substitutes, most of these do not fulfil the basic cartographic rules, e.g. avoiding text overlaps.This paper discusses the various workarounds addressing this problem, and introduces the author’s solution, which extends Leaflet’s GeoJSON class with automatic labelling functionality. The new class displays labels for point, line or polygon features. Labels can be placed either on right or left side of points or automatically for better fitting. Markers for points are only displayed if their labels can be drawn without overlaps. Label text is specified either by property field name or a user-specified function. It is also possible to specify priority order of features (higher priority labels are drawn first) and to customize label styles.
