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

You can now search and download the imagery data from Aerial Digimap by the year it was flown.

This allows you to be sure that you are downloading only the latest data, but it also allows you to download multiple images for the same location taken on different dates. We currently have data from 1998 through to 2016, with more English and Welsh images coming for 2016. When you are in Aerial Download you can see the extents of each year using the Show Availability Grid tool on the right side of the map as shown in the image above.

There is a table below detailing how many 1x1km images there are for each year, with the majority coming from 2013 to 2016, but some of the older images will be very useful to compare to the newer ones where they overlap:

Year Number of Images
1998 165
2000 855
2001 891
2002 75
2003 11
2005 423
2006 4,620
2007 7,799
2008 5,757
2009 25,066
2010 35,607
2011 18,642
2012 16,619
2013 54,534
2014 71,404
2015 81,378
2016 18,769

 

Here are two images of Lerwick taken 8 years apart:

As you can see there has been construction in the West of the area with new buildings and car parks added.

We hope that you find the ability to make this sort of comparison useful for your research. If you have any questions about this or any other aspects of the Digimap service then please don’t hesitate to contact us.

EDINA is very pleased to announce that Digimap Roam will be updated on Thursday 17th May 2018 to the new version currently available as beta. This change will apply to all Digimap Collections.  The beta version has been available since November 2017 and as a result of feedback we have continued to improve it, adding some useful new features:

  • A “locate me” button – puts a pin on the map according to your current location
  • A “coordinate capture” tool – under Map Information, allows you to click a point and copy/paste the coordinates into other applications
  • A Variable width side panel to offer a larger map window

We are very excited about the new Roam, which has a fresher feel and a more modern look; it’s tablet-friendly with tools that are easier to find and use.  All the main functions are located in the top left hand area, with a pull-out side panel ensuring maximum visibility of the map.

The new version of Roam will appear at the top of the list of applications in each Collection and will be labelled “Updated”. The previous version for each Collection will still be available until 31st July 2018:

We will be running a webinar about the new version of Roam on Wednesday 23 May from 1- 2pm. You can register for this here http://edina.ac.uk/training-and-events. Places are limited, but the webinar will be recorded and available to view later on our YouTube channel. Help pages for the new version of Roam will also be available.

As ever, we welcome feedback on Digimap. Please don’t hesitate to get in touch using any of our social media channels or use our email address or telephone number:

The Points of Interest (PoI) data is great for research and you can make fantastic looking maps too as we have been showcasing on our twitter account. You have certainly been making the most of it too, with 16,877 PoI downloads being made since May 2015. Here are 3 dot density maps we made to show a single class of PoI data:

Points of Interest: Camping and Caravanning Dot Density mapPoints of Interest: Cattle Grids Dot Density mapPoints of Interest: Allotments Dot Density Map

However until today you had to take all the different classes of points for your specified area and you were limited to taking no more than 10,000 Km2 in a single download. As PoI data is split into 9 groups, 52 categories and over 600 classes (see the full scheme here), we though it would make things easier if we exposed some of this hierarchy in Digimap’s Data Download service.

You can now select one or more of the groups or categories to download, taking some of the data processing load off you and making your downloads more manageable. Being able to filter the features in your download by group or category means smaller downloads so we have also removed the limit on the area you can take; you can now take the whole country in one download if you want.

One note of caution though, the PoI data has around 4.5 million records and is over 1gb in size as a simple CSV file. So if you are taking national coverage you may want to only take one group or a few categories to minimise the amount of data you are dealing with.

To select a group or category of features simply add PoI data to your basket then use the drop down menu in the layers column to choose what you are interested in.

We hope that you find this change really improves the accessibility of the Points of Interest data, we look forward to seeing some of the interesting analyses and maps you produce!

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

Lidar Point Cloud Forth Rail Bridge

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:

Digital Terrain Model and Digital Surface Model (DTM and DSM) England

  • 25cm: 2009-2015
  • 50cm: 2009-2015
  • 1m: 2010-2016
  • 2m: 2010-2015

  • 2m: 2010-2016
Point Cloud Scotland

  • Phase 1: 2011-2012
  • Phase 2: 2013-2014

 

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:
