OS OpenData Basemap information

Features & Benefits
High-resolution raster backdrop map data includes:
  • a comprehensive range of features such as railways, airports, ferries, cities, towns, other settlements and geographic names.
  • full Great Britain coverage
  • uncluttered and clean mapping
  • small to large scale

As one of a range of backdrop basemap services developed by Esri UK, GB BaseMap is derived from enhanced vector versions of OS OpenData products Strategi and Vector Map District. Enhancements include additional road and street labels at mid- and large scales to improve the level of content. The basemap is designed to be used as a backdrop to analysis and any additional overlaying data layers. The subtle cartographic design provides clean and consistent mapping from small to large scale.
