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The data can be found in the Withdrawn Datasets category in the Data Download interface and is currently available in its original tiles and format.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Withdrawn Datasets (OS Collection):

Along with the updated data, Ordnance Survey have recently withdrawn three datasets: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

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.

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.

As well as releasing the new OS MasterMap Water Network Layer earlier this month, we have also updated a number of datasets available in the Ordnance Survey collection. Most notably this month we have updated OS Open Map – Local, the most detailed OpenData product available from Ordnance Survey. OS Open Map – Local was initially released as a beta product in March 2015. The October 2016 release of Open Map – Local marks the end of the beta period and provides the first main version of the dataset.

The first main release of Open Map – Local has a few changes over the prevous beta version, including:

  • improved road information
  • addition of Car Charging Points sourced from the National Charge Registry
  • enhancements to the features included in the Important Buildings feature class
  • creation of a raster version optimised for display at 1:10,000 scale, this will be the replacement for OS Street View which is no longer updated and will be withdrawn by OS in March 2017
