In the absence of a time machine, it is difficult to imagine what the landscape of the past looked like or how much the world has changed. Obviously, we can find clues or descriptions in various sources, but getting the bigger picture is more challenging! This is where maps come in – scaled-down, approximate representations of the details of the surrounding world, using various symbols, colors, and text. As products of scientific knowledge and tools specific to certain historical periods, but also of the cartographers' imagination, maps differ by their scale, projections, coordinate systems used, accuracy/precision, or content/purpose. Some of them were created "in the office" – based on older documents and descriptions, others – based on quick sketches or visual reconnaissance in the field, while the most precise and costly ones were based on trigonometric and astronomical measurements, carried out with increasingly advanced technical means.

Created in the context of a land taxation reform and a detailed land-use mapping project applied across the entire monarchy, the cadastral map of Bukovina from 1854-1856 is an exceptional achievement for several reasons. For its creation, the most modern working techniques and scientific knowledge of that period were used; its "backbone" was provided by the preliminary development of a network of accurately determined geodetic points in the field. The details (e.g., buildings, roads, parcel boundaries, lands with various uses) were marked at a large scale (1 cm on the map corresponds to 28.8 m on the ground), hence the need to divide it into multiple sheets—nearly 5,000! For their assembly, a unique coordinate system was created, specific only to Bukovina, whose "point zero" was located near the village of Gălănești. The Greenwich meridian was not used as it is today, but rather the "Rădăuți meridian"! With a little mathematical imagination, considering the dimensions of the sheets covering the province, it turns out that for their physical assembly, a plot of 1,270 m² (nearly 13 ares!) would be required, with a maximum length/width of approx. 56/40 m. It is certainly the most extensive and detailed map of Bukovina, although, for obvious reasons, it was probably never fully assembled! Today, technological advancements and the use of geographic information systems allow us a different approach, namely, its reconstruction in a digital environment.

The main objective of our project was the creation of an interactive mapping application that allows the visualization and overlaying of the 1854/56 plans onto the current situation. To make this possible, several activities were carried out, each with its own challenges. As they progressed, we concluded that a simple cartographic presentation would still be incomplete for our journey through time. Thus, we added various historical information and period images, meant to clarify certain aspects and enhance the user experience.

Born from a historical-geographic passion and fueled by the curiosity of finding geoinformatic workflow solutions, the project holds practical value for historical documentation (e.g., how settlements evolved over time, the delineation of past land properties, the identification of areas of historical interest for the preservation of cultural and architectural heritage), studies on land use dynamics and human impact on the environment, or genealogical research. Perhaps more importantly, this initiative recalls a major achievement, unique in the Romanian extra-Carpathian region, making it accessible to the general public.
