OSNI Fusion

OSNI Fusion is a seamless, polygonised dataset with a more intuitive structure that provides data in layers based on real-world features. It also contains life cycle information and unique identifiers for each feature, which can be used to link other datasets to the mapping.

Key Features

• the topographical data model and structure allows interactive access to information on features and makes Fusion suitable for a wide range of spatial queries
• 3 themed topographical features of Land Parcels, Transport Casings, and Water Polygons form a complete coverage of Northern Ireland
• 9 themed features – Buildings, Ground Cover, Grid Extent, Land Intertidal Sea, Legacy Features, Perimeter, Structures, Text, and Transport Network – provide additional real-world topographical details
• each feature has a unique 36 character ‘Fusion ID’ which is a globally unique identifier (GUID)
• each feature has life cycle information like the start of life and change date
• additional information is stored for each feature like the types of buildings
• other vector, raster, and address data can be used to increase functionality for example vector mapping can be overlaid with orthophotography using suitable software
