The book is concerned with the statistical theory for locating spatial sensors. It bridges the gap between spatial statistics and optimum design theory. After introductions to those two fields the topics of exploratory designs and designs for spatial trend and variogram estimation are treated. Special attention is devoted to describing new methodologies to cope with the problem of correlated observations.

We are in an age of big data where all of our everyday interactions and transactions generate data. Much of this data is spatial – it is collected some-where – and identifying analytical insight from trends and patterns in these increasing rich digital footprints presents a number of challenges. Whilst other books describe different flavours of Data Analytics in R and other programming languages, there are none that consider Spatial Data (ie the location attached to data), or that consider issues of inference, linking Big Data, Geography, GIS, Mapping and Spatial Analytics. This is a ‘learning by doing’ text book, building on the previous book by the same authors, An Introduction to R for Spatial Analysis and Mapping. It details the theoretical issues in analyses of Big Spatial Data and developing practical skills in the reader for addressing these with confidence.

Modern Statistical Methodology and Software for Analyzing Spatial Point Patterns Spatial Point Patterns: Methodology and Applications with R shows scientific researchers and applied statisticians from a wide range of fields how to analyze their spatial point pattern data. Making the techniques accessible to non-mathematicians, the authors draw on their 25 years of software development experiences, methodological research, and broad scientific collaborations to deliver a book that clearly and succinctly explains concepts and addresses real scientific questions. Practical Advice on Data Analysis and Guidance on the Validity and Applicability of Methods The first part of the book gives an introduction to R software, advice about collecting data, information about handling and manipulating data, and an accessible introduction to the basic concepts of point processes. The second part presents tools for exploratory data analysis, including non-parametric estimation of intensity, correlation, and spacing properties. The third part discusses model-fitting and statistical inference for point patterns. The final part describes point patterns with additional "structure," such as complicated marks, space-time observations, three- and higher-dimensional spaces, replicated observations, and point patterns constrained to a network of lines. Easily Analyze Your Own Data Throughout the book, the authors use their spatstat package, which is free, open-source code written in the R language. This package provides a wide range of capabilities for spatial point pattern data, from basic data handling to advanced analytic tools. The book focuses on practical needs from the user’s perspective, offering answers to the most frequently asked questions in each chapter.

Welcome to the proceedings of the 2010 International Conference on u- and e-Service, Science and Technology (UNESST 2010) – one of the partnering events of the Second International Mega-Conference on Future Generation Information Te- nology (FGIT 2010). UNESST brings together researchers from academia and industry as well as prac- tioners to share ideas, problems and solutions relating to the multifaceted aspects of u- and e-services and their applications, with links to computational sciences, mat- matics and information technology. In total, 1,630 papers were submitted to FGIT 2010 from 30 countries, which - cludes 223 papers submitted to UNESST 2010. The submitted papers went through a rigorous reviewing process: 395 of the 1,630 papers were accepted for FGIT 2010, while 50 papers were accepted for UNESST 2010. Of the 50 papers 8 were selected for the special FGIT 2010 volume published by Springer in the LNCS series. 27 papers are published in this volume and 15 papers were withdrawn due to technical reasons. We would like to acknowledge the great effort of the UNESST 2010 International Advisory Board and members of the International Program Committee, as well as all the organizations and individuals who supported the idea of publishing this volume of proceedings, including SERSC and Springer. Also, the success of the conference would not have been possible without the huge support from our sponsors and the work of the Chairs and Organizing Committee.

Spatial Models and GIS

Spatial models have been in existence in the environmental and social sciences for a long time. More recently, specialised software for the capture, manipulation and presentation of spatial data, which can be referred to as `Geographical Information Systems' (GIS), have vastly increased the range of possibilities of organising spatial data by new and efficient ways of spatial integration and spatial interpolation. Coupled with the improvements in data availability and increases in computer memory and speed, these novel techniques give rise to new types of spatial models which exploit the technological potential now available, make better use of existing data, stimulate the collection of new data and open up new ways of working with geographic information. This book explores the potential and impact of GIS on spatial modelling.

Since 2007, the Belgian School at Athens has undertaken excavations on the Kefali or Buffo hill, east of the village of Sissi, on the north coast of Crete where a Minoan site was occupied approximately between 2500 and 1200 BC. This volume is the follow-up of an earlier one on the 2007-2008 excavations (published as 'Aegis 1') and presents a preliminary report on the excavations carried out in 2009 and 2010. It concentrates on the different zones examined within the cemetery and settlement. There are also reports on the Late Minoan pottery, site conservation and environmental analysis as well as a paper on the use of GIS at Sissi.

As Earth faces the greatest mass extinction in 65 million years, the present is a moment of tremendous foment and emergence in ecological science. With leaps in advances in ecological research and the technical tools available, scientists face the critical task of challenging policymakers and the public to recognize the urgency of our global crisis. This book focuses directly on the interplay between theory, data, and analytical methodology in the rapidly evolving fields of animal ecology, conservation, and management. The mixture of topics of particular current relevance includes landscape ecology, remote sensing, spatial modeling, geostatistics, genomics, and ecological informatics. The greatest interest to the practicing scientist and graduate student will be the synthesis and integration of these topics to provide a composite view of the emerging field of spatial ecological informatics and its applications in research and management.

Elements of Spatial Data Quality outlines the need and suggests potential categories for the content of a comprehensive statement of data quality that must be imbedded in the metadata that accompanies the transfer of a digital spatial data file or is available in a separate metadata catalog. Members of the International Cartographic Association's Commission on Spatial Data Quality have identified seven elements of data quality: positional accuracy, attribute accuracy, completeness, logical consistency, lineage, semantic accuracy and temporal information. In the book the authors describe: components of each data quality element, possible metrics that can be used to measure the quality of each criteria, possible testing and rating schemes, and how these parameters might differ from a producer or user point of view. Finally no volume of this nature would be complete without a chapter devoted to necessary future research in this subject area. The chapter points out areas in need of further investigation and speculates about the use and transfer of digital spatial data in tomorrow's electronic world and at developments in presenting specified data quality information in a visualization. This book will be of interest to all of those individuals involved in geographical information systems and spatial data handling.
