Interacting with Big Geospatial Data

Methods for Virtual Exploration and Visual Analysis
Advances in capturing techniques such as laser scanning and photogrammetry have significantly increased the volume of geospatial datasets. Big geodata has become an important asset for analysis and decision-making, but also poses a challenge for state-of-the-art visualisation techniques. This article presents research results addressing this problem for the infrastructure and planetary science application domains. The methods discussed here enable users to fluently explore and efficiently analyse the growing wealth of geospatial data.  The data volume of 3D reconstructions is steadily growing for two reasons. Firstly, there is a demand to increase the accuracy of data acquisition, now reaching even sub-millimetre... (read more)

The Age of Geospatial Data Ethics

Today, we are seeing a sudden awakening around the topic of data ethics, writes Abigail Page. Although ethics have always existed, the recent scandals around Facebook and Cambridge Analytica have changed the tone of the discussion – especially as we learn that our personal data is actually a monetizable resource. These recent developments, which have received the full glare of the media spotlight, should be considered as a ringing alarm clock that is impossible to stop. On the positive side, these scandals have forced citizens to ask some important questions: what happens to my data, how much do I want... (read more)

Effective Use of Geospatial Big Data

Server Solutions Hold the Key
The heart of any geospatial analysis system, regardless of its location or configuration, is increasingly becoming the server. All systems face a similar challenge, whether the system is in the ‘cloud’, a secure data centre or on a single machine running in an office. This challenge is primarily the ability to deal with the ever-increasing quantities and variety of data the world now produces at an unprecedented rate. This article explains how, for mission-critical systems, purposely designed software is required that has been tested in the most demanding environments. Try doing it cheaper and you only end up wasting money.... (read more)

Research Reveals Scope of Open Geospatial Data Across Europe

Open data is available from the majority of European National Mapping, Cadastral and Land Registry Authorities (NMCAs), a new survey has found. Research by the Open European Location Services (ELS) Project reveals that 98% of respondents provide at least some of their data free of charge. Of these, 37% make all their data available under an open licence.  Whilst open data models vary, more than 85% provide view and search services, 72% enable downloads and 67% allow its re-use in products. Users include public authorities, public services, research and education as well as commercial companies. This survey provides a snapshot... (read more)

Big Geospatial Data Helps Modernise the Statistical Field

Geospatial tools and information are going mainstream, as is evident following the recent opening of a new data science campus at the Office for National Statistics headquarters. Niall Conway explains how the fields of Statistics, Big Data and Geospatial are beginning to converge in order to deliver better insights to government. Technology, including geospatial, is revolutionising how we go about our lives. With the help of satellites, computers, smartphones and other devices, it is estimated more data has been created in the past two to three years than in the entire previous history of the human race. However, while this... (read more)

ELS Project Uses Geospatial Open Data from Official National Sources

Open data services developed using official national sources of geospatial information have been demonstrated for the first time at the Geospatial World Forum. Conference delegates received an exclusive preview of the first test services from the Open European Location Services (ELS) Project which is being coordinated by EuroGeographics, the membership association for Europe’s National Mapping, Cadastral and Land Registration Authorities. The services are being delivered through a customer interface developed by ThinkWhere and include pan-European topographic data (EuroGlobalMap), an open cadastral Index map of property level information and a regional gazetteer of geographical names. With the exception of the EuroGlobalMap... (read more)

Hiring Geospatial Employees

Are you looking to change your job during the year? Or maybe you’re looking to recruit and will be part of the hiring process. Adena Schutzberg provides some timely advice drawn from a master of successful appointments who uses heuristics. Over the last 20 years I’ve probably read several hundred requests from students, career changers and those already involved in geospatial technology asking for help getting a job. In contrast, I’ve read very little about how to hire the best people from those groups. Luckily Henry Ward, CEO at eShares, detailed his four hiring principles and six hiring heuristics in...
