Linking Geospatial Data 2014

LGD14 Barcamp, featuring open plan space and beanbags.

I was very pleased to attend this event co-organised by the World Wide Web Consortium (W3C) through the SmartOpenData project, the Open Geospatial Consortium (OGC), the UK Government (data.gov.uk), the Ordnance Survey (OS) and Google. Hosted by Google Campus London, the two day event comprised presentations, lightening talks and a barcamp, all focussing on the use of geospatial data within the world of Linked Data. It was refreshing to be amongst researchers, users, developers and commercial folk all working in this area; I for one picked up some good ideas to help with my research project and hopefully my contributions were of use.

It was certainly good to bring together the camps working in this area: the geospatial technologists on the one side and the web folks on the other (And people like me who have one foot in each camp, as well as limbs in other domains, my primary domain being digital cultural heritage of course). To make this stuff work it’s going to take both groups working together through their respective consortia, the W3C and OGC.

Geosemantics; the story so far

Semantic Web Rubik's Cube by dullhunk

Semantic Web Rubik’s Cube by dullhunk

Into the second month of the PhD now and things are starting to coalesce and take shape. A framework for development, testing and deployment of proposed demonstrators is emerging and I’m making good headway demystifying the world of geosemantics (at least, it’s becoming clearer in my head!).

So, as well as continuing with the literature review, I’m knitting together a whole bunch of tools:

  • Java Development Kit (JDK) – the programming language at the heart of it all
  • Maven – a project management and comprehension tool
  • Eclipse – open development platform
  • Jena – a Java framework for building Semantic Web applications
  • Oracle 11g – relational Database Management System (RDBMS) with Spatial and Semantic components
  • D2RQ – a system for accessing relational databases as virtual, read-only RDF graphs.
  • AllegroGraph – a graph database
  • Prolog – logic programming
  • Protégé – ontology editor and knowledge-base framework
  • GeoSPARQL – query language for geospatial data stored as RDF
  • ArcGIS – Geographic Information System for data preparation, processing, etc
  • GeoServer – open source GIS server written in Java that allows users to share and edit geospatial data.

I’ll be posting more along the journey. Next steps will be to complete the literature review, submit stage reports and use some real archaeological data. Exciting stuff!
