Geo-referencing

Geo-referencing files allow tiles of map data to be located in their correct geographical position when loaded into a geographical information system (GIS). This is achieved by loading in files alongside the data files that contain the National Grid corner coordinates for each tile. This is especially useful if more than one tile of data is being loaded at once, as it allows for a true geographical depiction of the data.

About geo-referencing

When raster data is supplied to you, it is not georeferenced in any way. This means that tiles will not be set up in geographical relationship to each other when loaded into a GIS.

Below are TIFF World Files (TFW) that can be used to geo-reference raster data in ESRI® ArcView® and ArcInfo® together with TAB files for use with MapInfo®.

Please note there are some World Files available that contain only sea. Therefore there is no data available. These World Files have been created to allow customers to complete the coastline.
