Georeferencing files and land and sea tiles

Georeferencing files put tiles of map data in their correct position when opened in a GIS. Sea tiles complete your product coverage on-screen.


Download free TIFF World Files (TFW) that can be used to georeference raster data in ESRI® ArcGIS together with TAB files for use with MapInfo®. Additionally, we supply .jgw files for OS Street View® for geo-referencing JPEG tiles.*

Land tiles

Our land tiles complete land areas at each zoom level, as required. They define the spatial extents of each product, so you can apply a background colour of your choice to areas of the map that are not covered by Tidal Water.

Free download (Zipped Esri shape files)

Sea tiles

Our free sea tiles and supporting TIFF World Files are free to download and let you complete sea areas at each zoom level as required.

OS VectorMap® District and OS VectorMap® Local sea tiles are geo-tagged, so they don’t require additional world files.
