The National Public Transport Gazetteer (NPTG) for Ireland is a dataset containing geographical information for all cities, towns and other localities on the island of Ireland. It provides a standard reference for Ireland's National Public Access Nodes (NaPTAN) dataset.
When used in conjunction with NaPTAN NPTG provides automated public transport facilities (such as online journey planners) with a means of providing stop finding and route planning capabilities using consistent names for locations and stops.
