There are several ways to download different datasets from Digimap. The most commonly used are:
Data Download -offers all tiled data products. Each product is at a different scale and in different formats. Some are raster data and some are vector data. Now includes OS OpenData datasets and raster versions of OS MasterMap. New interface provides a Roam style map to make selection easier. Also includes access to 1:50,000 scale gazetteer as a single file. NB. although this is available in .csv format, the file is too large to open in MS Excel. You will need a database programme to read the whole file.
Also offers OS MasterMap layers (Topography and ITN) as GML vector data. Change only updates are also available. Use this if you want to created customised large scale maps in a GIS or CAD system.
Includes OS Boundary-Line® data, OS Code-Point® and OS Code-Point® with Polygons.
ShareGeo - used to download miscellaneous datasets (can also be used to deposit datasets you want to share with others)
