Resumen

The main objective of this study is to analyse the spatial structure of tourist accommodation in mainland Portugal. This study compares Point-Of-Interest (POI) from OpenStreetMap (OSM) with the Portuguese National Tourism Register (RNT), in order to assess whether open data can be an alternative to official data in countries where such access is difficult. Using geostatistical techniques such as Kernel Density Estimation (KDE) and Predominance Map, it evaluates the spatial distribution and regional disparities of various accommodation types. The results show a significant concentration along mainland Portugal's coastline and metropolitan areas and emerging clusters in inland regions. The research results show that official data is more important, but OSM data can be an alternative to this data, due to its free availability and quick accessibility. The study’s results will provide regional planning and development insights, enabling stakeholders to make informed decisions towards a more sustainable tourism industry.
