OS MasterMap replaces Land-Line

Land-Line data is being withdrawn in August 2008. After 1 August 2008 you will need to use OS MasterMap Topography layer instead of Land-Line data. Land-Line is the most detailed data available through the Data Download facility within Digimap's OS Collection. It has been replaced by OS MasterMap Topography layer, which is equally detailed and available through the MasterMap Download facility.

Two OS MasterMap Layers, Topography and Integrated Transport Network, have been available from Digimap's OS Collection since September 2007. These layers are available through the MasterMap Download facility. You can read more about OS MasterMap data on our OS MasterMap website and within the Digimap Help pages. Look in the sections under MasterMap Download and Data Information.

There are several software packages available which make the process of loading and viewing the OS MasterMap in GIS applications quite simple, more simple than using Land-Line data, in fact. These are in addition to 'built-in' converters supplied with the most recent versions of ArcGIS (Productivity Suite), MapInfo and AutoCAD software.

Viewing data

If you wish to simply view the OS MasterMap data (rather than undertake any spatial analysis, querying or manipulation), there is a simple viewer produced by Snowflake Software. It is called the OS MasterMap Viewer and can be downloaded for free (upon registration) from the Snowflake website.

MapInfo

The following applications are free and will load OS MasterMap, fully represented, into MapInfo:

• OSM2MIF written by Nigel James at the Bodleian Library. This can be downloaded from the Bodleian Library Map Room website: http://www.bodley.ox.ac.uk/guides/maps/translat.htm


• InterpOSe (Digimap Edition) from Dotted Eyes. This is available free of charge on registration with Dotted Eyes. It includes full OS MasterMap styling, and will convert data to various file formats, including Shape, TAB, mid/mif and DWG/DXF.

ArcGIS

The following applications are freely available:

• Productivity Suite 1.1. This is freely available to those licensed to use ArcGIS through Eduserv Chest. It contains MapManager and will convert OS MasterMap to Geodatabase format and comes complete with a number of layer files for representation (details can be found in the local installation folder of Productivity Suite). You will need a special Athens username and password to access the software download area. This should be available from your local Chest Representative or ESRI Technical Contact.


• InterpOSe (Digimap Edition) from Dotted Eyes. This is available free of charge on registration with Dotted Eyes. It includes full OS MasterMap styling, and will convert data to various file formats, including Shape, TAB, mid/mif and DWG/DXF.

AutoCAD

• InterpOSe (Digimap Edition) from Dotted Eyes. This will convert OS MasterMap to DXF and DWG and has a template file (.DWT) for representing the data using OS style. InterpOSe can be downloaded for free from Dotted Eyes website on registration there.

There are other packages and resources available which are detailed on our OS MasterMap website. Ordnance Survey also provide information about software which will read OS MasterMap data.

Instructions on using MapManager 9.1 and InterpOSe are included in the Digimap Help pages. Look in the section labelled "Using Data with GIS". If you have any questions about the information provided here, please contact the EDINA Helpdesk on edina@ed.ac.uk or 0131 650 3302.
