Data and code for walkability- and pressure-aware pedestrian tourism route optimisation in the historic centre of Palma (Mallorca, Balearic Islands, Spain)

Data and code supporting the article "Walkability- and Pressure-Aware Pedestrian Tourism Routes as a Service on Tourism Data Spaces: A GIS-Optimisation Framework for Palma (Mallorca, Balearic Islands)", submitted to ISPRS International Journal of Geo-Information. The deposit contains the inventory of 105 georeferenced points of interest of the historic centre of Palma de Mallorca, with expert tourist value, nodal and zonal pressure scores, expected visit time and thematic category; the four origin–destination matrices derived from the pedestrian network (distance, pedestrian travel time, and time penalised by walkability and by tourist pressure); and the three reproducible Google Colab notebooks that implement the workflow: extraction and cleaning of the pedestrian network from OpenStreetMap, construction of the origin–destination matrices by Dijkstra minimum-time paths, and the route optimiser, formulated as an Orienteering Problem and solved as a two-stage lexicographic mixed-integer linear program. The attributed pedestrian network itself is not redistributed, as its geometry derives from OpenStreetMap under the Open Database License; it can be regenerated with the first notebook. See README.md for the full description, the reproduction sequence, the coordinate reference system (ETRS89 / UTM 31N, EPSG:25831) and licensing details. The POI valuations, visit times and nodal pressure scores are prototype-level test data assembled to demonstrate the framework on a real network; they are not measurements of visitor behaviour in Palma.
