Earth Observation and Spatial Analysis

Its not often that political manifestos get into the specifics of the GeoSpatial industry, but the British Conservative party seem to have decided there is political gain in terms of spatial data.  Under the heading “Digital Land”, they say:

And we will use digital technology to release massive value from our land that currently is simply not realised, introducing greater specialisation in the property development industry and far greater transparency for buyers. To make this happen, we will combine the relevant parts of HM Land Registry, Ordnance Survey, the Valuation Office Agency, the Hydrographic Office and Geological Survey to create a comprehensive geospatial data body within government, the largest repository of open land data in the world. This new body will set the standards to digitise the planning process and help create the most comprehensive digital map of Britain to date. In doing so, it will support a vibrant and…

EEO-AGI Scotland Seminar Review : Prof. Jonathan Silvertown: 28th Apr

Earth Observation and Spatial Analysis

Edinburgh offers its inhabitants and visitors a large range of sights and events to occupy and entertain throughout the year, notably its annual festivals. As a stroll through many Edinburgh bookshops confirms, much interest also exists in investigations of the city’s rich heritage and natural environments.

In close proximity to the Drummond Street location of the seminar lies St. John’s Hill, where James Hutton (1726-1797), later billed the ‘father of modern geology’, once lived. It was here, in sight of the Salisbury Crags, that Hutton’s early geological observations were made. To this day, Hutton’s profound statement Image1 ‘…we find no vestige of a beginning, no prospect of an end’ – can be found etched into a large Clashach stone at the spot where Hutton’s house and garden once lay.

It was in this context – and that of other lauded figures of the Scottish Enlightenment such as Adam Smith and David…

EEO-AGI Scotland Seminar Review :

April 19, 2017 Leave a comment

Earth Observation and Spatial Analysis

The Edinburgh Earth Observatory (EEO) AGI-Scotland seminar series were delighted to host Stephen Cragg, transport planner for Transport Scotland on Friday the 31st of March, 2017. Stephen’s talk formed part of the seminar series’ ‘Future’ theme, in which GI professionals across a range of fields and disciplines examine the pervasive nature of technology, and the ways in which it is changing our world for the better (or for the worse).

The seminar was intriguingly entitled ‘Future Transport: I know where you were last night!”. Steven stated that the title was, in itself, a technique to garner curiosity from among the audience, and a question which he sought to answer in the concluding remarks of his talk.

Steven amusingly began his discussions on the premise that he knew his left from his right, but not necessarily his east from his west, setting the scene for a spatially-minded audience. He followed-up…

AGI(S) – EEO Seminars Update

March 8, 2017 Leave a comment

Earth Observation and Spatial Analysis

February 2017 witnessed the first Festival of Creative Learning at the University of Edinburgh.  To mark this, Friday 24th saw a pairing of the first and second seminars in a special ‘Future Techniques’ trilogy held as part of this year’s EEO-AGI(S) Seminar Series.

Dr. Paul Chapman of Glasgow School of Art’s School of Simulation and Visualization (SimViz) first asked: “Virtual Reality. Temporary distraction or real opportunity?”

For those of us old enough to remember some of the mixed efforts of the early 1990s (cumbersome games console add-ons and some questionable movies! – all discussed) this was an interesting update and a reminder of how the Computer Games industry has developed at enormous pace over the last few decades.  For those new to VR this was a comprehensive coverage of hardware and software platforms (such as Google Cardboard, Samsung Gear VR and the HTC Vive offering – tipped as one VR…

Amazon Outage makes for a Dark Cloud

March 1, 2017 Leave a comment

Earth Observation and Spatial Analysis

image1For some years now we have been led to believe that The Cloud gives us a  robust solution to providing software services (including GIS) which avoids the dangers of being dependent on individual servers, which risk loss of hardware, power supply, cooling and other points-of-failure.  This is a solution which has become increasing popular, with many organisations and services now dependent on it.  In theory, the Cloud spreads the risk over thousands of individual servers, physically located in different data centres at different sites spread across the different countries and continents.

Or that’s the theory.  The 28th Feb saw a failure of saw an outage of the US-EAST node of Amazon’s S3 service which has caused chaos across the web.  Amazon’s web services have grown from an infrastructure built to support their own online shopping business to underpin around 150,000 other web sites, services and smartphone apps around the world…

Citizens As Sensors: A Solution To Pollution?

January 16, 2017 1 comment

After the recent news from Friends of the Earth Scotland that there are now a total of 38 Pollution Zones in Scotland, up from 33 last year, we take a look at how geographic information, and particularly that created by citizens, is playing a role in our mission for breathe better air.

Scotland Air Pollution Zones 20

Scotland Air Pollution Zones 2016

Much of geography’s traditional role has been on air quality monitoring – enabling sensors with location information to help build up the map visualising the spatial variability of the usual pollutants: carbon monoxide, sulphur dioxide, nitrogen oxide and particulate matter (both PM25/PM10) – as well as air quality modelling – whereby we utilise various factors to forecast accurate(ish) predictions.

ScottishAirQuality.co.uk is currently the go to place to see historic and current forecasts of air quality, with summaries provided from 95 monitoring sites across the country.  A quick explore through the maps will highlight that the distribution of these sensors is limited, in turn creating more coarse outputs.  The issue of forecasting air quality is based on both our ability to effectively monitor the air as well as understand the way in which air pollutants move within city spaces.  How we simulate the latter through computer models – or Computational Fluid Dynamics (CFD) – is a challenge currently being addressed at the Scottish Government-backed CivTech tech accelerator (perhaps another cause for more 3D geospatial data?)

Tech is seemingly everywhere these days and the Future / Smart Cities agenda is no different and with it, a new lease of life for Citizens as Sensors; empowering local residents with the tools to plug the gaps on data, particularly where environmental monitoring is concerned.  For Geographers in the room who’ve read Michael Goodchild know this as Volunteered Geographic Information, or VGI (an essential read all the same!).

With citizen science however comes the age old argument over data quality and relying on ‘the crowd’.  Recent publications about citizen science from the Centre for Ecology & Hydrology and an EC Science for Environment Report highlight that fears over data quality can be mitigated by robust tools and can strengthen citizens’ data to inform policy and practice.

When it comes to creating a smarter community-led air quality sensing network, there’s no been any short supply recently…DISCLAIMER: what follows is a run down of some efforts but there’s no favouritism intended here!

One of the first kickstarter successes in this field was the Air Quality Egg, which enabled you to user connect an egg to your wifi (queue first ‘internet of things’ hint), collecting information on all the usual suspects using the fixed egg and sharing this ‘live’ to their platform.

Another fixed solution which has impressed has been UCL’s ExCiteS department spin-off NGO, Mapping For Change, and their Air Quality Monitoring Project.  Although seemingly exclusive to London and silent for a couple of years now, the project deployed fixed tubes around the city to provided hourly readings and uses a very nice map interface to help you explore these monitoring sites (NB: ExCiteS team, if you’re listening, we’d love to see that gorgeous custom Leaflet clustering method open sourced!).

show the world how clean the air is around you!

Since then the list of initiatives has grown rapidly, of course including wearable devices that hook into your phone as well as more and more internet-enabled devices.  Aircasting is a notable offering; allowing users to acquire a wearable air quality device that tracks, shares and even visualises the air around you.  Visual displays of air quality is a fantastic awarenesss raiser, and many illuminating vests have followed however where AirCasting stands out from the crowd is that it has open sourced much of it’s app, making it possible to create your own custom-designed sense Arduino device!

cleanspace-freevolt

Freevolt: devices without batteries? yes please!

Another favourite is CleanSpace, which is a free app for users but requires you to purchase an air quality monitoring tag if you want to contribute.  The CleanSpace Tag is also a personal air pollution sensor but comes with some pretty high tech features, as it’s (supposedly the first device) powered by Freevolt, which uses wasted energy in wireless signals to power itself…undoubtedly something every smart watch owner wishes was true for their device.

Whilst the plethora of new apps to get citizens involved with monitoring our environment can be seen as further engaging the masses to think more about issues like air quality, there remains an argument that this diversity of offering can in fact dilute citizens’ contributions, particularly where apps and agencies continue to operate in silos and not as ‘one geography’.  With the rise of citizens’ digital presence (or digizens), perhaps now is the time to look at how we hone and align this vast knowledge and encouraging a new era of environmental action.

Is 2017 The Year of 3D Geo?

January 4, 2017 1 comment

LiDAR scanning has captured the Forth Bridges in stunning 3D resolution and is being shared across educational bodies for use in interactive games, apps and virtual reality tours.

scottishten-forthbridges

The work, reported by the BBC yesterday, is in partnership with the Centre for Digital Documentation and Visualisation is a partnership between The Glasgow School of Art and Historic Environment Scotland, known as the Scottish Ten Project, which aims “to create accurate 3D data to help with their conservation and management, their interpretation and virtual access.”

The initiative is providing these datasets to encourage more interest in STEM (science, technology, engineering and maths) careers amongst young Scots and heralds an exciting time for 3D geospatial technology.

With the arrival of next generation high resolution aerial imagery from satellites and drones, alongside the continued advances in open source tools such as CesiumJS, LASTools and Mapbox’s new 3D features… is 2017 shaping up to be the year in which 3D geospatial goes mainstream?
