Digimap Update for the 2018-19 Academic Year

ecls/ / Data Changes & Additions, Digimap News, New Features, Of Interest

It is the start of a new academic year and we have introduced few new things for you to see in Digimap:

A New Home Page

Digimap has a new home page! It may look a little different, but it works in exactly the same way as the previous version. Responding to feedback from the community we have provided more detail about each collection in the left hand panel, including preview images of the data. Roam and Data Download are easy to find under each Collection’s tab.

Global Digimap

We are very proud to announce the launch of our new Global Digimap collection.  This is a new service, developed in response to requests for international data.  Initially Global Digimap will offer OpenStreetMap data but our objective is to develop the collection in partnership with the user community, so user feedback will shape both the content and functionality.  In return for this engagement, access to Global Digimap will be free of charge until July 2019.

We have asked all the Digimap Site Reps if they would like access to the service, if you can’t access Global Download then speak to your site rep about getting your institution switched on: List of Digimap Site Reps

There is a blog post with more detail about the Global Digimap Service.

Upgrade for Data Download

Following a lengthy beta phase, we have promoted the beta version of Data Download to a production service and this is now the default Data Download application for all Collections.  Ever mindful that work flows, and teaching and promotion materials may need updating as a result, we will continue to run the previous versions of both Roam and Data Download until the end of the year.  All saved maps and data download histories are available in both new and old versions.

New Licences

Digimap is now operating under new licences for 2018/19 so all registered users are required to accept the new terms.  This is a simple process which happens when you first log in. No re-registration is required and all saved maps and data download histories remain available as before.

Fresh faced new Data Download

ecls/ / Digimap News, New Features, Of Interest

We are delighted to announce that a new version of Digimap’s Data Download is now available.   This is a “beta” version so we will keep the current interface running while you explore the new improved service. We know that teaching and support materials may need to be updated so we hope that a transition period will help.

Data Download takes it’s new fresh-faced look from the recent updates to Roam, Digimap’s mapping facility.  The search bar is now at the top left hand side and all the action happens in the variable width side panel below it.  A big improvement is that you now have more ways to specify the area of data you need. In addition to defining a rectangle, you can now create an irregular polygon as your area of interest or a buffer zone from a point or line that you define. We’ve also added a “Locate Me” button* to help you easily find data for the area local to you.

The panel on the left now shows a straightforward and easy-to-use list of all available data and shows more clearly how much data can be selected in a single request, along with the availability grids for each product.

As ever, you can add multiple products to any data order, selecting the format, version and date from the basket prior to submitting your order.  As a new feature, you can now request your data to be sent to you as a single download, or for each dataset to be sent as soon as it’s ready.

Remember Digimap has a lot of previous versions of several datasets, dating back to 1999 in some cases. If you are interested in data for a specific date, use the Version drop down menu in the basket to access the archives.

We welcome any feedback you may have on the new interface;  please get in touch:

*Note that the Locate Me function may not work using Internet Explorer 11

Additional vertical aerial imagery for Digimap

ecls/ / Data Changes & Additions, Digimap News, Of Interest
Night time aerial imagery of London Waterloo and the London Eye
Night time aerial imagery of London Waterloo and the London Eye

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.

Huge Digimap Land-Line data archive (1999-2006) released

ecls/ / Data Changes & Additions, Digimap News, Of Interest

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:

Lidar Digimap: new collection of data available now!

ecls/ / Data Changes & Additions, Digimap News, New Features

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:

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.

Aerial Digimap: huge area of new images coming soon!

ecls/ / Data Changes & Additions, Digimap News, Of Interest

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.
