Do more with your GIS and understand the foundation of spatial analysis: geographic patterns and relationships. A geographic information system (GIS) enables so much more than mapping. A GIS inherently enables spatial analysis that can give you a better understanding of your geographic data. GIS analysis reveals answers to questions like: Where is it? Where's the most and least? How much is where? What's inside? What's nearby? What's changed But how do you get started? The second edition of The Esri Guide to GIS Analysis, Volume 1 shows how and more. With easier to read maps and text, The Esri Guide to GIS Analysis, Volume 1, second edition, dives beneath the surface of mapping, beyond displaying data to using it to reveal geographic insights. Learn the basic concepts of spatial analysis and GIS. Build on that understanding with essential map-building skills to unveil and display patterns and relationships. The Esri Guide to GIS Analysis, Volume 1, second edition, also includes a guide to online lessons that reinforce the concepts and demonstrate GIS application. Written for both new and experienced GIS users using an easy to follow format, the second edition of The Esri Guide to GIS Analysis, Volume 1 helps you build a foundation of the basic tasks needed to handle a wide range of analysis applications and prepares you for more advanced GIS skills.

A neuropsychologist takes ten different psychedelic drugs in this panoramic, profound and wildly entertaining investigation. 'Original and thrilling' Mike Jay, author of Psychonauts 'Utterly compelling' Mark Miodownik, author of Stuff Matters 'A hair-raising hurtle of a ride' Henry Shukman, author of One Blade of Grass 'The psychedelic world has been waiting for this book' Professor Erika Dyck Psychedelics may have made a comeback but they still remain a mystery. They are now a 'breakthrough therapy' for mental illness but the truth is we have only a vague idea how they work and there is a limit to what science alone can reveal. To have any hope of understanding them fully, we need first to broaden our view - dramatically - of what they are. In this daring, perception-shifting odyssey, clinical neuropsychologist Andy Mitchell takes ten different drugs in ten different settings, journeying from a neuroimaging lab in London to the Colombian Amazon via Silicon Valley and his friend's basement kitchen. His encounters with scientists and gangsters, venture capitalists and con men, psychonauts and shamans, as well as with the drugs themselves, reveal the reality of psychedelics in all their richness, darkness, hilarity, wonder and strangeness. We see that the drive to extract these substances from their indigenous and underground cultures comes with risk as well as opportunity, and that to make them safe or normal might ultimately destroy what makes them potent. We also see, more vividly than ever before, what makes them so rapturously enchanting and confounding. 'Beguiling, captivating, mind-expanding. It's impossible to read this book and not be tempted to replicate some of its wild, sanity-stretching forays into the peculiarities of human perception' Stuart Ritchie, author of Science Fictions 'A dazzling, timely book, as deep and poignant as it is madcap and hilarious' Mark Lythgoe, Director of the Centre for Advanced Biomedical Imaging, University College London

Learn how to get better answers in map analysis when you use spatial measurements and statistics. Spatial measurements and statistics give you a powerful way to analyze geospatial data, but you don't need to understand complex mathematical theories to apply statistical tools and get meaningful results in your projects. The Esri Guide to GIS Analysis, Volume 2: Spatial Measurements and Statistics, second edition, builds on Volume 1 by taking you to the next step of GIS analysis. Learn to answer such questions as, how are features distributed? What is the pattern created by a set of features? Where can clusters be found? This book introduces readers to basic statistical concepts and some of the most common spatial statistics tasks: measuring distributions, identifying patterns and clusters, and analyzing relationships. Updated with the latest and most useful software tools and revised explanations, each chapter in The Esri Guide to GIS Analysis, Volume 2 is organized to answer basic questions about the topic. Explore how spatial statistical tools can be applied in a range of disciplines, from public health to habitat conservation. Learn how to quantify patterns beyond visualizing them in maps. Examine spatial clusters through an updated chapter on identifying clusters. Use The Esri Guide to GIS Analysis, Volume 2, second edition, to understand the statistical methods and tools that can move your work past mapping and visualization to more quantitative statistical assessment.
