EDINA is pleased to announce the launch of Aerial Digimap, a new Collection offering aerial photography from Getmapping Plc.

The crystal clear imagery from Getmapping is 25cm resolution vertical aerial photography and the most detailed national coverage available. The largest proportion of the imagery dates from post-2011 with updates due every year.

Aerial Digimap offers both a mapping and a data download facility, both familiar to those who already have access to other Digimap Collections.

Aerial Roam offers the ability to view, annotate and print the aerial photographs as well as an overlay function to allow comparison with current Ordnance Survey mapping.

Aerial Download offers the ability to select specific locations for which to download the aerial photography for use in local desktop software. Data is delivered in jpeg format each with a corresponding world file (.jgw).

EDINA’s annual Geoforum conference for all its geospatial services and projects was held at the University of Edinburgh’s Institute of Geography this year. It was attended by nearly 50 delegates who came to find out what we have been up to over the past year and to see what we new things they can expect in the coming months.

The morning session started with talks from Tim Urwin, EDINA’s geo-data manager, and Guy McGarva, from the Geosupport team. Tim’s talk informed us all about the design decisions made when updating the OS MasterMap cartographic style. The new styling, originally developed for the Digimap for Schools service, has some great advantages over the old cartography and was put into service just after the conference:

Guy’s talk highlighted the main changes to EDINA’s geospatial offering in the last 12 months. We have mainly been working on things that you can’t “see” in Digimap with huge improvements to the way the service is delivered. We now can make sure that interruptions to the service are rare as it can be delivered from one of two physical locations at the University of Edinburgh.

One obvious change we delivered was the improved Digimap home page. This came about through work to make the service usable on a touch screen or tablet device. To ensure that the service could work on these devices we needed to use new web technologies meaning a redesign had to be carried out. We like the cleaner design but best of all you can now just click on the application you want to use, log in when prompted, and be taken straight to the thing you want to do. No more remembering to log in to the service before clicking the link in your Data Download email!

The next two talks were all about Aerial Imagery as EDINA will soon be launching the Aerial Digimap service. The new service will contain 25cm resolution aerial photographs for the whole of Great Britain from Getmapping.

Firstly we head from Richard Evans from Getmapping who spoke about the history of aerial imagery and also the modern technology and techniques that go in to it’s creation.

Then we heard from Ian Holmes from EDINA, who showed us what the new Digimap Aerial collection would look like. As with the other Digimap collections there will be Roam and Download interfaces to either view the data or to take it away to analyse in the user’s own software.

Ian also highlighted some of the interesting and quirky things captured in the images, such as the shadows of giraffes at Chester Zoo.

Please keep watching the blog and other Digimap information channels for an announcement on when the service will be launching.

After a good lunch spent networking we started on the afternoon session where we heard from two students and two members of teaching staff about their uses of Digimap and data from the services.

Firstly we heard from Trevor Draeseke who told us about his Masters Thesis, Visualising Geographical Information in Augmented Reality.

Trevor’s proof of concept mobile app the “Arthur’s Seat Augment Reality Visualiser” allowed the user to view geological data and other layered geographic information on the live video feed coming from the phones camera. He said his work was made possible by the “easy and flexible access to the underlying geographical information layers through EDINA’s Digimap Service.”

Next we heard from Kathy O’Donnell who is now in the first year of a PhD that is building on her MSc thesis on the Quarries of Hadrian’s Wall.

Kathy has been mixing layers from the various data collections in Digimap: Ordnance Survey, Historic and Geology, to identify where the Romans were quarrying the stone to build Hadrian’s Wall. Kathy’s work is one of the best examples of making use of the various collections we have seen and she is looking forward to hopefully being able to use Aerial Digimap as another important source of data.

After a short break we heard the perspective of teaching staff from the University of Stirling and Lancaster University. Firstly Phil Bartie, University of Stirling, talked about how Digimap Roam was useful for introducing students to digital mapping and and also that it was “very important that students and academics have access to high quality spatial data for teaching and research.”

The final talk of the day came from Duncan Whyatt and Gemma Davies from Lancaster University. Duncan first reminisced on life before Digimap, and how difficult it was to get hold of maps and spatial data. After subscribing they have concentrated more heavily on the data downloaded from Digimap in the Geography Department. Duncan and Gemma took us through the various exercises the students were given using data downloaded from Digimap at each stage of their degree. Duncan stated that “Digimap has underpinned Undergraduate teaching in GIS at Lancaster for 15 years…”

Despite showing how important Digimap is and has been in studying and teaching all four of the presentations contained mentions of what they’d like to see in the future and a final challenge from Duncan to stay relevant in a world with an increasing amount of alternatives. We have heard this challenge and are working with those who fund the service to make sure our offering stays up-to-date and continues to deliver what academia wants. However we would like to remind all users of Digimap to keep letting us know what you want from the service so we have enough evidence to shape future developments in the right way.

A final thank you to all those who gave a presentation, the Institute of Geography for providing a venue, and to all the attendees; we felt it was a very successful event and look forward to the next one in 2017.
