We are very pleased to announce that we we recently added WMS (Web Map Service) functionality to all Digimap Roam applications. This new facility allows you to pull in map data from a whole host of publicly accessible services allowing you to visualise a wealth of data in the familiar Digimap Roam interface. This is beta functionality, and there are a few areas that need further improvement but we were keen to get it out there as quickly as possible so that you could start making use of it. Whilst we continue to work on the functionality, we welcome any feedback you may have. Our contact details can be found at the bottom of this post.

The WMS functionality can be found in the Overlays menu panel on the left hand side:

WMS functionality

To add a WMS feed to your map you need to press the Add WMS Feed button, which will bring up the following window:

Add WMS Feed popup

You will need to paste the getCapabilities URL in to the ‘3rd Party WMS URL’ field at the top of the popup. This URL is usually in the following format, but may be different depending on the service:

https://[servername]/service?SERVICE=WMS&Version=1.1.1&REQUEST=getCapabilities

Having entered the URL the Get Layers button should become active, press this to retrieve all the layers available via the entered WMS URL. Finally add the layers to your map using the Add Layers to Map button to add them to your current map window. You can then control the opacity of each layer using the appropriate opacity slider and the order they are displayed by clicking and dragging. It’s possible to edit the names displayed e.g. to choose shorter names that are easier to see by pressing the edit button next to each entry:

WMS overlay panel controls

There are numerous WMS available for the UK, many of which are listed on data.gov.uk. The image below shows listed buildings (boundaries and category) published by Historic Environment Scotland on top of the 1st Edition 1:2500 County Series map published in 1896 in Ancient Roam:

Listed buildings pulled via WMS on top of historic map from 1896 in Historic Roam

There are also lots of WMS available that serve up global data and can be viewed using the latest Global Digimap collection.  One example of this is the General Bathymetric Chart of the Oceans (GEBCO), shown below in Global Roam centred on the Gulf of Mexico:

Bathymetric data via WMS on top of OpenStreetMap data in Global Roam

We have put together a help page which lists examples of a variety of WMS from different sources. Whilst we can’t guarantee that they will all work all of the time if you do come across a WMS that you think should work and have tested that it works in other software, such as QGIS or ArcGIS Online, please let us know so we can improve the service.

Known issues

As mentioned above, this is new beta functionality and as such there are a number of known issues and things to bear in mind:

  • Currently no warning messages are displayed if a WMS fails to load. If the data has not appeared after a reasonable period of time please try to access the data via the same URL in QGIS or ArcGIS Online. If the data does load in QGIS or ArcGIS Online please send the URL to us so we can investigate.
  • In some cases the Get Layers button will not return any layers. When this happens it is worth copying and pasting the text displayed if you visit the getCapabilities URL in a browser window in to the Advanced box.
  • WMS data is not included in print files.
  • It is not currently possible to edit the details of a WMS service or dataset names in IE11 as the wrapping in the edit window is not quite correct.
  • Some WMS URLs (including those published by the Environment Agency) are published with the HTTP prefix but in order for these to work in Digimap Roam you need to change the prefix to HTTPS instead.
  • The WMS must be able to supply data in the same projection of the current Roam application. All Roam applications use the British National Grid with the exception of Chart Roam and Global Roam which both use WGS84 Web Mercator. No warning is given if the WMS projection is not compatible with the current Roam application.
  • WMS entries in the Overlays panel are persistent between log-ins in the same browser, so if you add a WMS in Chrome, the same WMS entries will be available the following day in Chrome providing the browser cache/temporary storage has not been cleared overnight.
  • WMS entries added in one Roam application are also automatically available in all other Roam applications e.g. if you add a WMS in OS Roam it will also be available in Historic Roam etc.
  • There is no Get Feature information displayed for a WMS layer so you cannot click on a feature and get its attribute information. However the Legend for the layer is displayed in the WMS panel if you expand the layer.

We are very pleased to announce the release of Global Roam. This builds on the release of Global Download last week and allows users to browse global data in the familiar, user friendly, Roam online mapping interface. Global Roam is very much a work in progress and you will find that some of the standard functions are not yet available, but we were keen to get something out to users as soon as possible and we’d love to know what you think of it and where you think it can be improved.

As mentioned in our previous blog post, Global Digimap is available as a beta service as we look to build a suite of datasets, themes and formats that best meets the needs of our users. We will continue to develop the Global Digimap service over the coming months, shaped by the feedback that you give.

Global Roam delivers the familiar Roam interface with detailed global data sourced from Natural Earth and OpenStreetMap. The application includes the usual annotation tools (recently renamed ‘drawing tools’) along with global search functionality. The most zoomed out maps use Natural Earth data which changes to OpenStreetMap as you zoom in. Future plans include:

  • adding additional data from the rich OpenStreetMap dataset including point features
  • integrating the print interface to allow high quality printed maps up to A0
  • addition of the feature information tool allowing users to view the attributes of selected features
  • creating alternative grey-scale and colour basemap styles
  • inclusion of the measurement tools [update: these were added 30/08/2018]
  • customisation of the map through the Map Content panel

It’s worth mentioning that maps saved in Global Roam are not compatible with other Roam clients and vice versa as they use a different projection system. [update: this was resolved 30/08/2018]

Access to Global Digimap

During this development phase, and in return for engagement with the development process, the service will be free of charge for institutions that subscribe to another Digimap Collection. We would like to know what you like and don’t like about it, what features and what new data you would like to see added.  We can’t promise to include everything but the more we hear from you the better able we are to prioritise different requirements and create the best possible service.

If you would like access to Global Digimap please ask your local Digimap Site Representative to request access through the Digimap helpdesk and we will ensure your institution is switched on.

Get in touch

It is never too early to let us know what else you would like to see, we are very keen to hear your ideas of how we can make something really useful; our contact details are below:

We recently made available, through the Digimap Lidar Collection, a wealth of Vertical Aerial Imagery data captured by the Environment Agency for England.  The Environment Agency has been capturing vertical aerial imagery since 2006 on a project by project basis, so the coverage is not continuous across England. Availability grids for each year of data are available in the Lidar Download application. Data is available in some locations for multiple dates where the location has been surveyed on more than one occasion.

Some of the imagery was captured at night time giving an insight in to the effects of urban light pollution.

Data format

The data is supplied in the raster ECW (enhance compressed wavelet) format, which should be readable by most modern GIS and image processing software.  The data is tiled and tile sizes range from 1km x 1km to 5km x 5km and the resolution of the data ranges from 10cm to 50cm. There are three types of imagery available:

  • True colour – red, green, blue (RGB)
  • Near Infra-Red (NIR)
  • 4-band (RGBN)

Access

Lidar download is available to all institutions that subscribe to Aerial Digimap, meaning that subscribing institutions now have access to another detailed aerial imagery dataset.

For information on subscribing to Aerial Digimap, please see the subscription page.

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:

Mockup of the new Geology Roam interface

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.

Today we have made a huge amount of archived Land-Line data available to download from Digimap. You access the data through the Data Download application in the Digimap: Ordnance Survey Collection.  Land-Line was the pre-cursor to the OS MasterMap Topography Layer, and was the most detailed topographic mapping available from Ordnance Survey at the time. The archive released consists of annual snapshots of the whole of Great Britain from 1999 to 2006. This data will be vital for researchers who are undertaking longitudinal studies,  examining how areas have changed over time.

The data can be found in the Withdrawn Datasets category in the Data Download interface and is currently available in its original tiles and format.

Land-Line download location

Land-Line comes on 500m, 1km and 5km tiles depending on whether the area is Urban, Rural or Moorland.  It is supplied in National Transfer Format (NTF) which was the standard format of the time. We have put together a short help page that explains how to import this data in to common GIS and CAD applications which may be of use for anyone unfamiliar with this format of data.

IMPORTANT:  Between 2001 and 2006 Ordnance Survey carried it’s Positional Accuracy Improvement (PAI) programme. This means that there will be discrepancies in the positions of features on these maps and the OS MasterMap data: Read more on PAI

The Land-Line data that we have made available significantly bolsters the amount of detailed topographic data that is available for download from Digimap. The most detailed topographic mapping currently available from Digimap, OS MasterMap Topography Layer, is available for download going back to 2007. The addition of Land-Line data to Digimap means that users now have access to download the most detailed topographic mapping data for Great Britain going back a further eight years to 1999.

We hope you find this new addition of recent historic data useful, if you have any questions about the data please contact us:

May was one of the busiest in terms of dataset updates in the history of Digimap. Around 20 separate datasets have been updated bringing them bang up to date with the most recent data available from the data suppliers. All the updates are listed in the tables below, broken down by the Collection and service that they can be found in.

Withdrawn Datasets (OS Collection):

Along with the updated data, Ordnance Survey have recently withdrawn three datasets:

  • Land-Form PANORAMA
  • OS Street View
  • Meridian 2 (this was covered in an earlier blog post)

These withdrawn datasets are still available to download through the Ordnance Survey Data Download application in Digimap, but users should be aware that they are no longer updated by Ordnance Survey. Withdrawn datasets have their own separate category in the Select Data panel in OS Data Download, as shown by the image on the left hand side.

Aerial Digimap updates

March/April 2017 has been a busy couple of months for the Data Team who have been working hard to process a huge area of updated aerial imagery data from the data supplier, Getmapping. The update consists of around 80,000 individual 1km tiles, all captured in 2015, which is approximately 30% of the country.

Prior to the update just over 50% of the data was from 2013 or later; after the update 77% of the data is from 2013 or later.

This means that more up to date imagery is now available for viewing and download through Aerial Digimap for a significant proportion of the country.

The map below shows the approximate distribution of the updated data.

2015 update to Aerial Digimap data

This is the first update we have received from Getmapping, but we are expecting another update later this year containing imagery captured in 2016.

We will add this to the service as quickly as we can to ensure that the most up to date data is always available to Aerial Digimap users. In order to make it clear where the data has been updated, we will add an Availability/Reference Grid to Aerial Download so that users can easily identify if the imagery has been updated in their study area(s). This grid will be added to the system in the next couple of weeks.

We are still investigating the best way to make previous versions of the data available, but in the mean time only the most recent data is available through Aerial Roam and Aerial Download.

 

 

Webinar resources

We recently ran a webinar highlighting the data and showcasing a number of potential uses for the imagery. The webinar was recorded in full and is available on our YouTube channel. The slides used during the webinar and a transcript of all questions and answers are available on our help page.

Data information

The aerial imagery data in the service is 25cm resolution vertical aerial orthophotography supplied by Getmapping PLC, and is the most detailed aerial imagery available for the whole of Great Britain. As well as being a really interesting dataset the imagery also has a number of practical uses across a wide range of disciplines from urban planning and 3D modelling to land use and archaeological studies.

Aerial imageryAerial Digimap was only launched at the end of last year but the response from the Digimap Community has been amazing. The service already has thousands of active users who have created hundreds of thousands of screen maps. Users have downloaded tens of thousands of square kilometres of this data, for use directly in reports or GIS and CAD software.

 

Data updates

Whilst we’re excited to see such a high level of usage of the new service, behind the scenes our Data Team are currently processing the 2015 data which will be available in the service early next month. This is the first update we have received from the data supplier, Getmapping, and contains updates to around 80,000 tiles. This is a significant update as it covers roughly 30% of the country providing more up to date imagery for a large proportion of Great Britain. The map below shows the likely distribution of the updated 2015 data.
