RoadwayMap is a backdrop raster map product derived from NAVTEQ NAVSTREETS data, covering the British Isles (including Northern Ireland, Republic of Ireland, the Isle of Man & Channel Islands). It consists of a pyramid of raster layers, ideally suited for scales on screen in the range 1:1,000,000 to 1:3,000. There is also a vector layer of place names suitable for use with the Find command in a GIS.

RoadwayMap technical information
A workspace or project file opens all the layers and sets zoom layer thresholds that determine when the layers are visible, to allow smooth transition when zooming.
A georeferencing file positions each image and a seamless table opens all the files required for the current map view.
The nominal scale of the most detailed images in this set is 1:5,000 (about 12 inches to 1 mile) and the resolution is 10 dots/mm (254 dpi). Each pixel represents 1m square.
The British National Grid co-ordinate system is used.
The storage space required is approximately 7.0GB for 1:12,500 Scale British Isles coverage in MapInfo TAB\TIFF format. LZW compression is used.
Main formats available: TIFF, JPEG and others, along with georeferencing files for use in GIS.
