GIS solutions for London’s Crossrail. Wayne Marsh, Crossrail. Abstract. Crossrail is the largest civil engineering project in Europe and the largest single addition to the London transport network in over 50 years. It has been designed to provide a new railway network for London and the South East and carry 200 million passengers a year. Within Crossrail, GIS is being used through the entire lifecycle of the project, including design, construction and maintenance, integrating and joining up data such as BIM and Asset Registries. At the heart of the GIS solution is an Oracle Spatial 11g server acting as the master repository and spatial analysis tool, glueing the information together. This talk will discuss how Crossrail arrived at this solution, how it is currently being used and how we plan to enhance it in the future. To download a PDF of the seminar please click here. In addition, here are some facts about Crossrail that @oobr tweeted during the seminar: – Crossrail is so vast that has its own coordinate reference system – London Survey Grid. British National Grid was not accurate enough. – Crossrail route has to weave through not just existing tube lines but also the post office […]

Spatio-temporal linkage of real and virtual identity. Dr Muhammad Adnan, UCL Department of Geography. Professor Paul Longley, UCL Department of Geography. To download a PDF of the seminar please click here. Abstract. A name often provides an indication of its bearer’s cultural, ethnic and religious affinity in the real world (Mateos et al 2011), as well as the place in which he or she probably lives (Cheshire and Longley 2012). This presentation begins to consider whether and how tokens of virtual identity can be linked to the probable characteristics of people and places. We begin with a retrospective on two strands of work at UCL that has used computationally intensive analysis to classify populations into: (a) ‘naming networks’ based upon social similarities in naming conventions; and (b) ‘surname regions’, based upon locational proximity of people who share names with common geographic roots. Together, these two approaches offer the prospect of context-sensitive generalisation of the geography of naming conventions, as well as measurement of the long term effects of population change. The second part of the presentation begins to consider the linkage between georeferenced email addresses and the probable names of their owners. We begin a preliminary investigation of data harvested […]
