On 30th November 2017, we released Beta versions of our new Roam mapping application for all Digimap Collections. Log in to Digimap and click on each Collection to find the link to each new Roam:

New Geology Roam

The functionality of the new application remains the same, but we hope you agree that the updated look is easier to use.

Most importantly, BOTH versions of Roam (new and old) will run in parallel for an extended period of time to give users the opportunity to get used to the new interface. We will review this at the beginning of March 2018 with a view to establishing a date for withdrawal of the old application.

Known Issues

All applications have undergone thorough testing, but there are still a few issues that we working on, for example some elements can be slow using Internet Explorer. If you spot anything that is not behaving correctly, please report this to us.

We encourage you to try the new beta versions and we welcome any feedback you have.

On 3rd October 2017, we released a Beta version of a new Roam mapping client for Digimap’s Ordnance Survey Collection.  OS Roam – Beta is available next to the existing version, simply log in to the Digimap service and select Ordnance Survey Collection to view the new beta version:

OS Roam - Beta

Whilst the functionality remains the same, we hope you agree that the look and feel of the interface is more modern. The majority of functions are available from a new menu panel down the left hand side, which is hidden by default, maximising the area available for the main map element.

There are some issues we are aware of in this version, which we are working on, for example, some elements can be slow using Internet Explorer and Edge.

New versions of the Roam applications in all other collections will be available in due course. Both new and old versions will run side by side for an extended period of time to give users the opportunity to get used to the new interface.

We would encourage you to try the beta version and we welcome any feedback you have.

As mentioned at Geoforum earlier this year, we’re currently working hard on a new version of Digimap Roam. The new-look application will bring Digimap Roam, the online mapping tool in the Digimap family, bang up to date with the latest web technologies available. Whilst the functionality will remain the same, the look and feel of the interface will be more modern. The majority of functions will be available from a new menu panel down the left hand side which is hidden by default maximising the area available for the main map element. By utilising the latest technologies we will be able to add new functionality and make further enhancements to the application in the future.

The new interface makes further improvements to the experience on mobile devices, an area where we’re seeing an increase in usage across the service. A mock up of how the new Geology Roam interface might look is included below to give you an idea of the proposed layout and styling:

Currently we are on target to launch the new interface early in the first semester of the 2017-2018 academic year, but we will post progress updates on this blog as the new interface approaches completion. There will be a phased release with the new Roam applications with the Ordnance Survey Collection being first in line.

We appreciate that you may have teaching or lecture materials that may require updating as a result of this change in interface, so we will run all the existing Roam applications alongside the new versions so you can get up to speed with the new interface whilst the existing versions are still available. At the moment we anticipate running both versions in each Collection side by side until at least the end of the year. During this period we would welcome any comments and feedback that you may have.

As ever, if you have any questions about the new Roam, please do not hesitate to contact us.

We have now reached the end of the Lidar Digimap Preview. We hope that everyone who has used the service has found it a great way to access the Lidar data available. From now on the service will continue to be available to Digimap Users whose institution subscribes to the Aerial Digimap service.

Find out here if your institution subscribes

Despite the addition of Lidar Digimap, Aerial Digimap subscription prices will not be increased for the 17/18 academic year. We will also be looking to add further datasets to Lidar Digimap over the next 12 months, these include:

  • Additional Point Cloud datasets ideal for use in CAD software for creating 3D models like this one of the Forth Rail Bridge
  • Photography; aerial images captured at the same time as the Lidar data

We’d also like to thank the hundreds of people who took the time to fill in our user feedback survey on Lidar Digimap, we have seen a huge range of uses for the data across a very broad range of disciplines. This feedback exercise has been very successful and we will be making the draw to see who has won the Amazon vouchers very soon. Keep watching the blog for the announcement in the coming weeks.

If you would like any more information about the Lidar or Aerial Digimap collections or details on how to subscribe then please do not hesitate to contact us:

LidarToday we have launched our new Lidar Digimap Collection. The new Collection is available to preview for all Digmap users until the 31st of July 2017. Lidar data can be downloaded through the Lidar Download for use in GIS and CAD applications; there is no Lidar Roam application for viewing the data.

Lidar Point Cloud Forth Rail Bridge

The service allows you to download current and past Lidar data from the Environment Agency (EA), Natural Resources Wales (NRW) and Scottish Environmental Protection Agency (SEPA).

There is already a large amount of data available in the service but we are still processing some of the datasets. Once it has all been processed the service aims to have complete coverage of all the data available from these agencies, including the raw LAS point cloud data and Orthophotography captured during the flights (where available).

Lidar data is very useful when creating 3D terrains and models as can be seen from the images to the left and below. For creating 3D scenes such as the one below, it is very useful to use a Digital Surface Model (DSM) to create a surface and hillshading from which you can drape other data over, such as the imagery from Aerial Digimap in this example:

We are currently processing the following datasets and hope to have them available in the service shortly:

Dataset Availability and publication date
Digital Terrain Model and Digital Surface Model (DTM and DSM) England

  • Historical data: 1998-2015

Scotland

  • 50cm
  • 2m
Point Cloud England

  • 2005-2016
Orthophotographs England

  • 2006-2015

 

The data was collected for flood risk analysis and modelling and primarily follows water courses and coastal habitats. The data covers approximately 72% of England, 20% of Scotland and 70% of Wales. The image below shows the 1m resolution DTM coverage in England:

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 on top of Aerial Imagery

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.
