Mapping the World

The Mapping the World project last week saw 15 year 10 and 12 students from 4 local schools experience University life as a Geomatics student. Students were introduced to the world of geospatial engineering and learnt about how GIS is used in their everyday life (think snapchat maps), and how to measure height change of land using levelling.  The hi-vis jackets (or wally jackets as we like to call them) proved very popular with the flies on Exhibition Park but not so much with the students wearing them!

Using ArcGIS Online and the Survey 123 app students investigated how GIS can help with asset management around Newcastle University campus. Students were given free rein on which aspect of campus management they would like to investigate, projects covered everything from where to store your bike, where are the comfiest seat on campus and disability access routes. After exploring the campus whilst mapping, students concluded by presenting their findings using Story Maps to show off all their hard work. It was great being part of the Futureme programme inspiring the next generation to go into higher education.

Northumbrian Water Innovation Festival

Last week myself and a group of us attended the Northumbrian Water Group (NWG) Innovation Festival (#InnovationFestival18), intended to bring people from different areas together to think about and tackle challenges within the water industry (with a focus on NWG). More intriguingly Newcastle University had sponsored one of the 12 sprints, a sprint running all day for the full five days with the idea of developing concepts to solve a problem, with this in particular sprint focused on digital twins (#DigitalTwins). Other sprints included how utilities could better work together to map underground assets and one focused on how can we create a happier and more productive workforce. This was not a small event, with over 2000 people attending and over 500 business involved. In true festival style, the week began with a compulsary participation in a sing-along to ‘The greatest showman’…..

Crowds in main tent (the ‘Thunderdome’) to see guest Alexander Armstrong (of pointless fame).

Great ideas were bounded around, with people involved ranging from those in management positions in NWG, to researchers like myself all who had varied skills and interests, to NWG customers themselves! Ultimately in the Digital Twin sprint where we were most involved, great ideas were devised as to how these could help NWG, from devising a single database system as ‘a single source of truth’ to developing a digital twin for incidents such as bursts as well as one for the whole company for modelling the communication and data flows through personnel. I’m sure across the other 11 sprints more great ideas were involved, with NWG now left with the not so small job of deciding which of these to follow up on!

Work on a #DigitalTwin of a pipe burst which occured a couple of months earlier on the NWG network.

Thanks to all the effort of the organisers!

Viva success – Polpreecha Chidburee

On Tuesday Polpreecha Chidburee successfully passed his viva for his thesis entitled “Landslide monitoring using mobile device and cloud-based photogrammetry” (subject to minor revisions). Professor Phil Moore (internal) and Professor Jim Chandler (external, Loughborough University) were the two examiners. Polpreecha is now returning to Thailand to take up a lectureship position at Naresuan University. Well done and good luck in the future!

Thesis abstract:

Landslides are one of the most commonly occurring natural disasters that can cause a serious threat to human life and society, in addition to significant economic loss. Investigation and monitoring of landslides are important tasks in geotechnical engineering in order to mitigate the hazards created by such phenomena. However, current geomatics approaches used for precise landslide monitoring are largely inappropriate for initial assessment by an engineer over small areas due to the labour-intensive and costly methods often adopted. Therefore, the development of a cost-effective landslide monitoring system for real-time on-site investigation is essential to aid initial geotechnical interpretation and assessment.

In this research, close-range photogrammetric techniques using imagery from a mobile device camera (e.g. a modern smartphone) were investigated as a low-cost, non-contact monitoring approach to on-site landslide investigation. The developed system was implemented on a mobile platform with cloud computing technology to enable the potential for real-time processing. The system comprised the front-end service of a mobile application controlled by the operator and a back-end service employed for photogrammetric measurement and landslide monitoring analysis. In terms of the back-end service, Structure-from-Motion (SfM) photogrammetry was implemented to provide fully-automated processing to offer user-friendliness to non-experts. This was integrated with developed functions that were used to enhance the processing performance and deliver appropriate photogrammetric results for assessing landslide deformations. In order to implement this system with a real-time response, the cloud-based system required data transfer using Internet services via a modern 4G/5G network. Furthermore, the relationship between the number of images and image size was investigated to optimise data processing.

The potential of the developed system for monitoring landslides was investigated at two different real-world UK sites, comprising a natural earth-flow landslide and coastal cliff erosion. These investigations demonstrated that the cloud-based photogrammetric measurement system was capable of providing three-dimensional results to sub-decimetre-level accuracy. The results of the initial assessments for on-site investigation could be effectively presented on the mobile device through visualisation and/or statistical quantification of the landslide changes at a local-scale.

Geographical spread of teams relegated from the Premiership

Once again a discussion at the coffee break posed an interesting question. Is this the closest the relegated teams have been to each other in the history of the Premier league. Some quick googling suggested it probably wasn’t and 2011-12 would be the closest with the 3 relegated clubs being Bolton Wanderers,Blackburn Rovers and Wolves. And much like last time I wasn’t content with guesswork and wanted to try and calculate this properly.

As a Norwich City fan relegation is something I've grown very used to
As a Norwich City fan relegation is something I’ve grown very used to

From the previous blog post I had the locations for all of the football league grounds ( one caveat is that i haven’t considered that the clubs may have played at a different ground [although I did use Selhurst Park for Wimbledon and not Milton Keynes ) .  so it was a very simple piece of analysis where i used PostGIS to calculate the distance between each of the relegated clubs and summed the value together per year.

From the results below you can see that the guess was correct and 2011-12 did have the shortest distance with 16-17 coming second.

Football Travel – the cost of TV fixture changes

In recent years, television broadcasters have pumped more and more money into the football industry, resulting in Premier League clubs in particular receiving both more TV money and more TV coverage. This extra coverage, however, has come at a cost to the fan on the terrace. There are more and more instances of last-minute fixture alterations being made to accommodate televised games. These last-minute changes often result in fans having to rebook travel plans, getting home even later, or in some cases staying overnight in a hotel. I personally remember having to rebook trains twice, and book and subsequently cancel accommodation (losing my deposit) as an Aston Villa vs Norwich City game had its kick-off time changed twice because of TV.

In previous work we have investigated the travel times of football fans and how they could be affected by fixture changes. This looked at the additional time and difficult faced by travelling supporters but did not consider the cost of these changes. Therefore in this piece of work we wanted to determine which fixture changes would result in the biggest cost increase for a fan travelling to the game by public transport. For this we used an API from British Rail Fares Queries (http://www.brfares.com/api/ ) which allowed us to determine the both the cheapest possible advance tickets and the cheapest possible ticket that a fan could buy on the day. As in the previous work, the Google Travel API (https://developers.google.com/maps/documentation/distance-matrix/) was used to determine the amount of time travelling and whether a fan would have to stay overnight either the night before or after a match.

As we didn’t want to just consider the cost of new rail tickets but the cost of having to potentially spend more leisure time travelling to and from the game due to the fixture change, we wanted to apply a “cost” to the fan for each extra minute spent travelling. The Department for Transport determined a value of £8 per hour for a non-work related journey using their ‘Value of Time method (https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/313222/webtag-tag-unit-a1-3-user-and-provider-impacts.pdf).We consequently applied this cost to the time a fan would spend travelling to and from the game to give an approximate monetary value.

Finally, if the fixture meant a fan would have to stay overnight we added an extra £50 to the journey cost to represent an approximate value of a night in a cheap hotel. Whilst all of these costs make assumptions (that the supporter is diligent enough to buy the cheapest available Advance ticket to travel to the match when they are initially released, that the rearranged game means the purchase of an Off-peak ticket rather than another Advance ticket, that they will not be able to stay with friends) they are a first attempt at capturing the extra personal cost of these TV fixture moves.
