The Urban Data Management Society has organised international symposia at various locations throughout Europe since 1971, and UDMS 2013 marks its second visit to London. From its outset, UDMS has highlighted changes and trends in urban data and urban data management. However, the rate of emergence of new data and new technologies has never been as rapid as it is now. Trends including smart cities, smart phones, social media, 3D modelling, volunteered geographic information, building information modelling and the internet of things all generate information about the urban environment and the people who live there. Additionally the volume of data generated in part through such techniques has in turn resulted in research into big data how best to handle the data, analyse it, visualise it in different contexts. Thus the challenges and opportunities facing those working with these new types of urban data are manifold. Given this, the general theme for UDMS 2013 was "Recent and Emerging Trends in the Management of New Urban Data."

This book contains 20 papers selected from the long papers that were submitted for UDMS 2013. Each paper was reviewed by three independent academic reviewers from around the world, both for academic quality and for clarity in communication. The book is intended to be suitable for different readers from city planners and architects to academics, students and policy makers and those involved in urban planning.

The indomitable Baker Street duo travel to the still wild areas of South Texas to investigate the puzzling disappearance of an heir to the great estate in the part of the South West known as The Wild Horse Desert. The pair travel by steamship to the Texas coast and then overland to the Rancho Royal where mystery awaits them. This is the second Sherlock Holmes pastiche from celebrated cartoonist Dicky Neely. 'The Case of The Grave Accusation' had Holmes and Watson travel to the future to clear the name of their creator Sir Arthur Conan Doyle. The book featured input from the real life murder case brought against Conan Doyle a few years ago and received great reviews from Holmes fans.
