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.

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:

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

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.

Current version: October 2016
