An Integrated Spatial Data Infrastructure for Sustainable Tourism Planning: Development and Implementation in the Lake Ohrid Region
This study develops and implements an integrated Spatial Data Infrastructure (SDI) for the Lake Ohrid region that combines geodatabase design with advanced spatial modelling techniques to analyze tourism infrastructure patterns and identify sustainable development zones, offering a reproducible framework for decision-making in environmentally sensitive areas.

Planning a vacation often feels like a personal journey of discovery, but for the people who manage the places we visit, it is a complex exercise in balance. They must decide where to build a new hotel or a hiking trail without destroying the very nature that draws people there. This is the heart of sustainable tourism planning, a field that relies heavily on geography. At its core, this work asks a simple question: where do people go, and why? To answer it, researchers use tools that map the invisible connections between roads, historic sites, natural landscapes, and the buildings where travelers stay. For decades, these maps have been created in isolation, with one team drawing roads and another mapping forests, often without a way to make the two pictures fit together perfectly. This disconnect can lead to poor decisions, where development happens in the wrong places or sensitive areas are overlooked.
In the Lake Ohrid region, a place of ancient beauty shared by North Macedonia and Albania, researchers have built a new kind of map-making system to solve this problem. Lake Ohrid is one of the oldest and deepest lakes in Europe, a UNESCO World Heritage site teeming with unique life and surrounded by historic towns. Because the area is so precious, every new building or road must be carefully considered. The researchers, led by Bashkim Idrizi and his team, created a unified digital framework called a Spatial Data Infrastructure. Think of this not just as a storage locker for maps, but as a single, living workspace where information about hotels, roads, hospitals, cultural sites, and the environment all live together in a structured way. Instead of having separate files that don't talk to each other, this system brings everything into one place, allowing computers to analyze how these different elements interact.
The team fed this system with a vast amount of information, organizing nearly 300 different types of geographic features. They included the locations of every hotel and restaurant, the entire road network, the boundaries of villages, and the precise spots of religious and historical sites. They also layered in data about the environment, such as climate patterns and the shape of the land. Once this massive digital foundation was set, the researchers let the system do the heavy lifting. They used computer models to see where tourism facilities were already clustered, how easy it was to reach them from the main roads, and which areas were most suitable for future growth. They looked for patterns, asking if the current distribution of hotels was random or if it followed a specific logic.
The results painted a clear picture of the region's tourism landscape. The analysis showed that tourism development is not scattered randomly across the landscape. Instead, it is heavily concentrated along the southern shore of the lake, particularly in and around the city of Ohrid. The system revealed that about 72 percent of all tourism facilities are located within two kilometers of a main road, and nearly 85 percent are within five kilometers of a major cultural heritage site. This confirms that accessibility and proximity to history are the primary drivers of where businesses choose to set up. The southern lakeshore emerged as the clear hotspot, where the convenience of travel meets the beauty of the water and the richness of the past.
To test if their system was working correctly, the researchers built a model to predict where new tourism development should happen based on the best combination of factors: easy access, closeness to the lake, and proximity to cultural sites. When they compared this model's predictions with the actual locations of existing hotels and restaurants, the match was striking. About 68 percent of the current facilities sit exactly where the model said they should be. This strong agreement suggests that the model accurately understands the rules that govern tourism growth in this region. The researchers also tested the model by slightly changing the importance of different factors, like making roads slightly more important than the lake, and found that the overall results remained stable. This means the system is robust and reliable, not easily swayed by small shifts in how the data is weighted.
The study concludes that this new approach offers a powerful way to manage sensitive environments. By integrating all the data into one system and using it to run consistent, repeatable analyses, planners can make decisions based on clear evidence rather than guesswork. The framework they built for Lake Ohrid is not a one-time fix for a single problem; it is a method that can be copied and used in other places where nature and tourism must coexist. It proves that when we organize our geographic knowledge carefully, we can see the hidden patterns of our world and plan for a future that protects the places we love while allowing them to thrive.
