OS MasterMap: Change-only Update release on 24 March

ecls/ / Data Changes & Additions

The next release of Change-only Update data for OS MasterMap will be put into service on Tuesday 24 March 2009. The currency date of the new data will be 20 January 2009.*

Change-only Update (CoU) applies only to the OS MasterMap data. It does not apply to any other data product.

EDINA collates all the data changes released by Ordnance Survey over a 6-month period, and makes these available through Digimap approximately every 6 months. The previous update was released in September 2008.

What is the point of Change-only Update?
Change-only Updates enable you to update your data holding without needing to store multiple copies or versions of the same data. By taking only the changes to the data you hold you can minimise the storage requirements for your data, while still maintaining an up-to-date dataset. This is particularly useful if you are studying changes to an area over time.

Most users will not need Change-only Update. CoU is only useful to you if you already have a full copy of the original data to which you can apply the changes.

How do I download CoU?
You can download Change-only Updates only for data orders you have already submitted within Digimap’s Mastermap Download facility. Go to the Your Account page within Mastermap Download and scroll down to the table of Orders.

You will see a list of all your previous Orders, and in the final column you will see whether or not CoU is available for that Order.

If CoU is available, click the radio button in the far left column for the Order you require. Below this table, you will see two buttons in a blue box:

Click the first button to Order Change-only Update. The data file will be delivered in the usual way: you will receive one email to say your Order has been received and is being processed, and a second email to say your data is ready for collection.

If you submit a new order for OS MasterMap data, by defining the Layer, Themes and your chosen area, you will automatically receive the latest version of the data; this will include all the latest changes. Change-only Update will therefore not be available for such an Order until the next batch of CoU is released.

Example
You submit an Order for data on 20 March 2009. In the Orders table under Your Account, the Order details say that CoU is not available. This is because you already have the latest version of the data.

If you submit a second Order for data on 27 March 2009, you will also see that the order details say that CoU is not available. Again, you have the latest version of the data; it includes the changes which were released on 24 March.

If you go back to look at your first Order (submitted on 20 March) on 2 April 2009, you will see that COU is now vailable for this Order. This is because the changes released on 24 March are now available; they were not available when you submitted the original order.

* Although the latest update is dated 20 January 2009, it takes time for Ordnance Survey to process and release these data, to send them out to EDINA and for EDINA to process and load the data into the database. This accounts for the time delay between the “freeze date” of the database (20 January 2009) and the release date (24 March 2009).

Training: booking now open

ecls/ / Training & Events

EDINA would like to announce that booking is now open and there are spaces available on the following Digimap training courses, open to staff members (and postgraduates for the MasterMap courses) in UK higher and further education institutions:

  • Digimap Collections: 31 March-2 April 2009 – Leeds University
  • OS MasterMap for Users: 22 April 2009 – York University

The following courses will be offered this year, but booking is not yet open:

  • Digimap Essentials: 4 June 2009 – Bilborough College, Nottingham
  • Digimap Collections: 9-11 June 2009 – Exeter University

Further details of course content and learning objectives can be found on our website. You will also find listings and booking forms (where open) for these and all other EDINA training events here: http://edina.ac.uk/events/

This page contains details of all forthcoming EDINA courses and workshops which may interest staff within subscribing institutions, including multimedia services courses to be announced soon.
We strongly encourage site representatives to attend an OS MasterMap course if they have not done so already. Other members of staff and postgraduate students from institutions which subscribe to Digimap are also welcome. Note that all attendees MUST be registered users of Digimap’s Ordnance Survey Collection in order to participate in the OS MasterMap training.

Running the courses is subject to a sufficient level of interest. If you are uncertain about the relevance of a course for your needs, please get in touch with EDINA for advice at edina-training@ed.ac.uk

All EDINA training courses are free of charge. Regretfully, however, we will charge £25.00 per person for each day of absence of which EDINA is not given prior notice. This is due to the increasing number of no-shows at courses.

Lunch will be provided for all full-day attendees and refreshments will be available throughout the day. If you have any questions about Digimap or these courses, please do not hesitate to contact us.

GML data translation from Dotted Eyes

ecls/ / Digimap News, Help

Dotted Eyes, a well established digital mapping solution provider, has produced an edition of their InterpOSe GML translator specifically for EDINA Digimap users.

The Digimap Edition of InterpOSe will translate OS MasterMap GML data from Digimap’s MasterMap Download facility and convert it to various file formats, including Shape, TAB, mid/mif and DWG/DXF. InterpOSe deals with both Topography and ITN layers, and is tailored specifically for data from Digimap.

InterpOSe (the Digimap Edition) is free for Digimap users upon registration with Dotted Eyes. Please visit their website for more information and to download a copy of InterpOSe:

Withdrawal of Land-Line

ecls/ / Data Changes & Additions, Digimap News

Digimap will cease to deliver Land-Line.Plus data at the end of August 2008.

As a registered Digimap user you may continue to hold and use any Land-Line.Plus data you already have until 31 July 2009. Beyond this date, you will be required to delete any Land-Line.Plus data you hold, and will not be licensed to use it thereafter.

Land-Line map of urban area

Land-Line.Plus has been replaced by OS MasterMap Topography Layer. These data are available from Digimap’s MasterMap Download facility, within the Ordnance Survey Collection. The OS MasterMap Topography Layer is as detailed as Land-Line.Plus but contains a much richer attribute set. It is also available in GML format, rather than NTF.

More information about OS MasterMap can be found within the Digimap Help pages.

OS MasterMap replaces Land-Line

ecls/ / Data Changes & Additions, Digimap News, Help

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.
