Systematization of cartographic sources and their comparative analysis is a challenging scientific task, accomplishment of which enables creating a more objective picture of the past. The geographical approach is inseparable from the historical one, and historic-geographical studies are an integral factor in a comprehensive scientific research. Many cartographic sources on the North-Western Black Sea Region are far from being studied and even systematized, some of them remain hardly known, and many of those that have been studied need to be adequately explained and rethought. The most noteworthy geographical features located within the borders of modern Moldavia, neighboring Romania and Ukraine, are depicted on some of the oldest maps. In the period of the 16th–18th centuries, the foundation for detailed mapping of the territory and creating large-scale overview maps was laid, including the works by G. L. Beauplan, V. M. Coronelli, D. K. Cantemir. G. A. B. Rizzi-Zannoni. A comprehensive topographic study of the North-Western Black Sea Region began only at the turn of the 18th-19th centuries, when the first survey and topographic maps were compiled, which enabled not only getting a general idea of the geography of the region, but also navigating the area quite confidently.
