Events, Statistics, Geospatial Data and the UN

The FIG Working Week in Helsinki was well organised, well attended and achieved by collaboration. So is much else in the geospatial business. Jointly organized by FIG and the two Finnish members of FIG and the National Land Survey of Finland, the working week was a substantial amount of good technical and strategic papers and presentations, as well as a strong cultural element. In the UK, GEO Business demonstrated the diversity, health and general state of our industry and profession. In the UK, there are concerns affecting the industry from austerity to “Brexit”. These are ongoing and largely out of... (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. Both commercial and government organisations recognise the enormous fiscal, operational and... (read more)

Ordnance Survey Producing Geospatial Data Model for Malta

Ordnance Survey (OS), the first national mapping agency in the world to digitise its geospatial database, is developing the first geospatial data model for Malta. The project, known as MaltaMap, is part of a desire to build a modern Spatial Data Infrastructure across Malta’s various government departments through the SIntegraM Project. It consists primarily of the islands of Malta and Gozo. Working alongside project lead, the geospatial solution provider IIC Technologies, OS has created a detailed base map model that provides an accurate representation of the built and un-built environment of the islands. The OS team are building on their... (read more)

Collaboration and Big Data - ISPRS Geospatial Week 2017

Ian Dowman reports on the ISPRS Geospatial Week (GSW) giving a good indication of current developments in photogrammetry, remote sensing and spatial information science and the way in which this is progressing in China. ISPRS has now established the GSW as a regular biennial event. This year it was held at Wuhan in China, hosted by LIESMARS, the geomatics centre at Wuhan University. The meeting inevitably had a Chinese flavour to it, but did demonstrate a number of interesting trends. The programme was divided into eleven workshops, each organised by one or more ISPRS working group, so although the themes... (read more)

Geospatial Data in Support of 3D Cadastre

Zooming in on Recent Technical Developments
The urbanization trend is leading to an increasing number of people living in cities, thus also placing new demands on cadastral registration. To be able to register the complex infrastructures and built-up areas properly, the cadastre will need to consider the third spatial dimension. The 3D cadastre is based on 3D parcels (spatial units) which are single volumes (or multiple volumes) of space. Although the technology offers numerous possibilities for implementation of the 3D cadastre, there are still some open issues, as this article explains. We live in a three-dimensional world. Over the past decades, there have been an increasing... (read more)

Blockchain in Geospatial Applications

Ian Dowman has written an introduction to blockchain and gives some examples of applications which are relevant to readers of 'Geomatics World'. The article is based on a piece in 'GIM International' by Jonas Ellehauge (2016), and also uses a number of other sources. Many people will find Blockchain a difficult concept, but Wikipedia is a good starting point: “A blockchain – originally block chain is a continuously growing list of records, called blocks, which are linked and secured using cryptography. Each block typically contains a hash pointer as a link to a previous block, a timestamp and transaction data.... (read more)

New Opportunities for Geospatial

The sun is rising, and spring is very much in the air. The six nations rugby is over (I’ll hold back on any commentary) and thoughts are turning towards the summer. Geospatial activity has been constant over the last couple of months with some very big industry issues (such as the scourge of UK instrument theft) being discussed. RICS has finished the 2018/19 evening lecture series with some very strong lectures on The Red Atlas - the Soviet Union Secretly Mapped the World (www.press.uchicago.edu/ucp/books/book/chicago/R/bo24760505.html), soon to be featured in the RICS Land Journal (www.rics.org/uk/news-insight/publications/land-journal), and a final lecture on marine/offshore...

Geospatial Sciences at UCL

We must occasionally look like Monty Python’s Judean People’s Front, carefully honing their differences with the Peoples’ Front for Judea. We are Geomatic Engineers, interested in Geospatial Sciences. How many MSc degrees do we need to cover our subject? The answer at UCL, until this year, was quite a few: Surveying, Hydrographic Surveying, GIS, Geomatics for BIM (and going back further, Geodesy, Photogrammetry, Remote Sensing, and others in the distant past). The differences mean a lot to us, but the university authorities occasionally raised a weary collective eyebrow and wondered how necessary it all was. At the same time, of... (read more)

UK Government Announces New Geospatial Commission

In his budget on 22 November, the Chancellor announced a new Geospatial Commission which is committed "to maximise the value of all UK government data linked to location, and to create jobs and growth in a modern economy." The Commission will work with government and the Ordnance Survey (OS) to work out how Mastermap can be made freely available, particularly to small businesses. The announcement is a further boost to the UK’s status as a world leader in digital innovation and is a recognition that there are many services dependent on location and that databases of geospatial information are used,...
