OS Open Map – Local (OML) was recently added to the Digimap Roam application, giving users the ability to create maps online with a detailed, vector open dataset. OML is the most detailed vector mapping product available from Ordnance Survey as Open Data. We have added this dataset to the following map views in Digimap Roam:

Map View Default Print Scale
Neighbourhood View 1:10,000
Street View 1:5,000
Detailed View 1:2,500

The dataset is rich in features and includes detailed building outlines and Car Charging Points, which are sourced from the National Charge Registry.

Ordnance Survey first released OML as a beta product in March 2015 and Digimap users have been able to download this dataset via the Data Download application since April 2015. The October 2016 release of OML marks the end of the beta period and provides the first main version of the dataset.

OML is intended to be used as a detailed basemap on which to visualise your own data and is designed to be an alternative to OS Street View, which will be withdrawn in March 2017 by Ordnance Survey.

The cartography team at Digimap have worked hard to implement a consistent style with that of the smaller scale VectorMap District product, ensuring a familiar look and feel between the two Open Data products. Contours from the OS Terrain 50 product are included when viewing the data in Roam, to give greater context especially in rural and hilly areas.

We are pleased to announce the addition of two new datasets to the Digimap Ordnance Survey Collection, which are available to download through the Data Download application. Both these datasets are detailed network datasets and form part of the OS MasterMap family of products. The datasets should prove useful for individuals carrying out detailed network analysis using the road and river network of Great Britain.

OS MasterMap Highways Network

OS MasterMap Highways Network is a new dataset from Ordnance Survey which provides the most detailed road network dataset available for Great Britain. The new Highways Network product is a replacement for OS MasterMap Integrated Transport Network (ITN), which will be retired at some point in the future. Highways Network was built using ITN as the base network and then further improved adding information from other authoritative sources including the National Street Gazetteer (NSG) and local authorities in England and Wales.

OS MasterMap Highways Network with OS MasterMap Topography Layer

Highways Network is provided in GML format as a single, national dataset covering the whole of Great Britain. This is a large dataset and is available through Digimap as a single download of 1.1GB in size.

Ordnance Survey have produced a number of supporting documents that are available for download directly from their website. We recommend that you consult these before using the data.

Current version: June 2016

OS MasterMap Water Network Layer

OS MasterMap Water Network Layer is a new network dataset from Ordnance Survey that represenets the centrelines of watercourses including flow direction and suplementary information.

OS MasterMap Water Network Layer is provided in GML format in 5 x 5km tiles. Water network features that cross tile boundaries are included in all tiles that they cross, so the data is called ‘hairy data’ due to the presence of these ‘hairs’ around the edge of each tile. This means that some processing is required to de-duplicate the features that cross tile boundaries if your order contains data from more than one 5 x 5km tile.

OS MasterMap Water Network Layer is projected in the ESPG 7405, which is a British National Grid projection that also includes the Z value using Ordnance Datum Newlyn.

Ordnance Survey have produced a Getting Started Guide which describes the process of importing the Water Network Layer in to common GIS packages.

EDINA’s annual Geoforum conference for all its geospatial services and projects was held at the University of Edinburgh’s Institute of Geography this year. It was attended by nearly 50 delegates who came to find out what we have been up to over the past year and to see what we new things they can expect in the coming months.

The morning session started with talks from Tim Urwin, EDINA’s geo-data manager, and Guy McGarva, from the Geosupport team. Tim’s talk informed us all about the design decisions made when updating the OS MasterMap cartographic style. The new styling, originally developed for the Digimap for Schools service, has some great advantages over the old cartography and was put into service just after the conference:

More Details about the new Cartography

Guy’s talk highlighted the main changes to EDINA’s geospatial offering in the last 12 months. We have mainly been working on things that you can’t “see” in Digimap with huge improvements to the way the service is delivered. We now can make sure that interruptions to the service are rare as it can be delivered from one of two physical locations at the University of Edinburgh.

One obvious change we delivered was the improved Digimap home page. This came about through work to make the service usable on a touch screen or tablet device. To ensure that the service could work on these devices we needed to use new web technologies meaning a redesign had to be carried out. We like the cleaner design but best of all you can now just click on the application you want to use, log in when prompted, and be taken straight to the thing you want to do. No more remembering to log in to the service before clicking the link in your Data Download email!

The next two talks were all about Aerial Imagery as EDINA will soon be launching the Aerial Digimap service. The new service will contain 25cm resolution aerial photographs for the whole of Great Britain from Getmapping.

Firstly we head from Richard Evans from Getmapping who spoke about the history of aerial imagery and also the modern technology and techniques that go in to it’s creation.

Then we heard from Ian Holmes from EDINA, who showed us what the new Digimap Aerial collection would look like. As with the other Digimap collections there will be Roam and Download interfaces to either view the data or to take it away to analyse in the user’s own software.

Ian also highlighted some of the interesting and quirky things captured in the images, such as the shadows of giraffes at Chester Zoo.

Please keep watching the blog and other Digimap information channels for an announcement on when the service will be launching.

After a good lunch spent networking we started on the afternoon session where we heard from two students and two members of teaching staff about their uses of Digimap and data from the services.

Firstly we heard from Trevor Draeseke who told us about his Masters Thesis, Visualising Geographical Information in Augmented Reality.

Trevor’s proof of concept mobile app the “Arthur’s Seat Augment Reality Visualiser” allowed the user to view geological data and other layered geographic information on the live video feed coming from the phones camera. He said his work was made possible by the “easy and flexible access to the underlying geographical information layers through EDINA’s Digimap Service.”

Next we heard from Kathy O’Donnell who is now in the first year of a PhD that is building on her MSc thesis on the Quarries of Hadrian’s Wall.

Kathy has been mixing layers from the various data collections in Digimap: Ordnance Survey, Historic and Geology, to identify where the Romans were quarrying the stone to build Hadrian’s Wall. Kathy’s work is one of the best examples of making use of the various collections we have seen and she is looking forward to hopefully being able to use Aerial Digimap as another important source of data.

After a short break we heard the perspective of teaching staff from the University of Stirling and Lancaster University. Firstly Phil Bartie, University of Stirling, talked about how Digimap Roam was useful for introducing students to digital mapping and and also that it was “very important that students and academics have access to high quality spatial data for teaching and research.”

The final talk of the day came from Duncan Whyatt and Gemma Davies from Lancaster University. Duncan first reminisced on life before Digimap, and how difficult it was to get hold of maps and spatial data. After subscribing they have concentrated more heavily on the data downloaded from Digimap in the Geography Department. Duncan and Gemma took us through the various exercises the students were given using data downloaded from Digimap at each stage of their degree. Duncan stated that “Digimap has underpinned Undergraduate teaching in GIS at Lancaster for 15 years…”

Despite showing how important Digimap is and has been in studying and teaching all four of the presentations contained mentions of what they’d like to see in the future and a final challenge from Duncan to stay relevant in a world with an increasing amount of alternatives. We have heard this challenge and are working with those who fund the service to make sure our offering stays up-to-date and continues to deliver what academia wants. However we would like to remind all users of Digimap to keep letting us know what you want from the service so we have enough evidence to shape future developments in the right way.

A final thank you to all those who gave a presentation, the Institute of Geography for providing a venue, and to all the attendees; we felt it was a very successful event and look forward to the next one in 2017.

This summer our cartographic team have been busy working on a new style for OS MasterMap Topography layer. These are the maps displayed at the three most detailed zoom levels in Digimap OS Roam. The original style, created more than ten years ago, followed the official style published by Ordnance Survey and has undergone little change since its creation. Later this year Ordnance Survey are making significant changes to the underlying MasterMap data so we thought it was high time the cartography was refreshed to give it a more modern feel.

The design brief had three broad requirements:

  • make it look ‘nicer’!
  • tone down the colours to allow annotations to stand out more
  • use the same colours as OS VectorMap Local, the second most detailed data product

The images below show the original and new styling for a number of areas which highlight the improvements that have been made in both urban and rural areas.

Changes to styling in urban areas:

MasterMap urban original stylingMasterMap urban new styling

The colours in urban areas have been muted, removing the large areas of yellow and making ‘unclassified’ land appear with hatching rather than as blank areas on the map.

Improvements in text styling:

MasterMap original text stylingMasterMap updated text styling

Text labels have been updated to emphasise building names and reduce the size of the labels for named urban areas.

Updated rural styling:

MasterMap original rural stylingMasterMap updated rural styling

Styling in rural areas with mixed land use is a challenge as there are multiple types which need to be conveyed to the user. We have increased the number of shades of green and improved the symbol spacing and placement in order to improve the appearance of these areas. Additionally we have changed the fill colour for tracks allowing them to be more easily distinguished from paved roads.

Updated foreshore styling:

MasterMap original foreshore stylingMasterMap updated foreshore styling

Foreshore areas now display using the yellow ‘sand’ colour, making them far easier to visualise.

We hope you like the new style, however the original style can still be accessed from the Basemap menu in OS Roam:

We are now at the start of a new academic year and Digimap has new licence agreements in place for the Ordnance Survey, Geology and Historic Map and Data Collections. You may have noticed already that you have been asked to agree to the licence again when you logged in.  This is because some of the terms are different and you are required to agree to these new terms prior to accessing the data within the service.

When you login you will notice the Licence Agreements button at the top right of the home page.

Licence Agreement Button

Clicking on this will allow to you to view the licences you have agreed to and to agree to those you have not yet agreed to.

New Licence Agreements 2016

If a Collection has a new licence, the applications (e.g. Roam and Data Download) in that Collection will also appear grey. By trying to access an application which has a new licence, you will automatically be taken through the process of agreeing to it if you have not yet done so.

All you need to do is accept the licence and restate your purpose for using the service (which may or may not have changed since you agreed to the previous licence) and you will have access to the service once more.

If you have any questions or need any help or guidance have a look at the Agreeing to Licences for Digimap Collections section half way down the following help page:
