Learn how to build native, cross-platform mapping apps with this comprehensive and practical guide, using the MVVM pattern About This Book Enhance the user experience with the power of ArcGIS runtime SDK for .NET. This clear, well segregated book has all the information you need on ArcGIS Runtime SDK. Just name it—this book has it! This highly practical book empowers you to build your own custom application! Get to know the inner details of ArcGIS Runtime SDK from our experts, in this book written by Ron Vincent, with 24 years' experience in the GIS industry and many in GIS training. Who This Book Is For This book caters to long-term users of Esri’s technologies that are new to mobile development or are transitioning from older Esri technologies such as ArcGIS Engine. It is also for users who are unfamiliar with Esri or GIS and are in need of a mapping solution for either their desktop or a mobile platform, or both. The book requires knowledge of .NET. What You Will Learn Understand and implement the MVVM pattern using MVVM Light Create and add layers from offline and online resources such as ArcGIS Online or ArcGIS for Server Create a 2D or 3D map and decide what kind of symbology to use Symbolize the layers based on the geometry Search and find objects in the layers Geocode an address and create a route using an address Edit layer objects from online content and offline content Test the application using test-driven development and then build and release the application for the intended audience In Detail ArcGIS is a geographic information system (GIS) that enables you to work with maps and geographic information. It can be used to create and utilize maps, compile geographic data, analyze mapped information, share and discover geographic information and manage geographic information in a database. This book starts by showing you where ArcGIS Runtime fits within Esri’s overall platform strategy. You'll create an initial map using the SDK, then use it to get an understanding of the MVVM model. You'll find out about the different kinds of layers and start adding layers, and you'll learn to transform maps into a 3D scene. The next chapters will help you comprehend and extract information contained in the maps using co-ordinates and layer objects. Towards the end, you will learn to set the symbology, decide whether to use 2D or 3D, see how to implement 2D or 3D, and learn to search and find objects. You'll also get to grips with many other standard features of the Application Programming Interface (API), including create applications and finally testing, licensing, and deploying them. Once completed, you will be able to meet most of the common requirements of any mapping application for desktop or mobile platforms. Style and approach This comprehensive book takes a completely practical approach, where every chapter explains the important concepts and demonstrates a practical application of them in a hands-on manner.

Boost your confidence and get the competitive edge you need to crack the exam in just 21 days! About This Book Day-by-day plan to study and assimilate core concepts from CISSP CBK Revise and take a mock test at the end of every four chapters A systematic study and revision of myriad concepts to help you crack the CISSP examination Who This Book Is For If you are a Networking professional aspiring to take the CISSP examination and obtain the coveted CISSP certification (considered to be the Gold Standard in Information Security personal certification), then this is the book you want. This book assumes that you already have sufficient knowledge in all 10 domains of the CISSP CBK by way of work experience and knowledge gained from other study books. What You Will Learn Review Exam Cram and Practice review questions to reinforce the required concepts Follow the day–by-day plan to revise important concepts a month before the CISSPexam Boost your time management for the exam by attempting the mock question paper Develop a structured study plan for all 10 CISSPdomains Build your understanding of myriad concepts in the Information Security domain Practice the full-blown mock test to evaluate your knowledge and exam preparation In Detail Certified Information Systems Security Professional (CISSP) is an internationally recognized and coveted qualification. Success in this respected exam opens the door to your dream job as a security expert with an eye-catching salary. But passing the final exam is challenging. Every year a lot of candidates do not prepare sufficiently for the examination, and fail at the final stage. This happens when they cover everything but do not revise properly and hence lack confidence. This simple yet informative book will take you through the final weeks before the exam with a day-by-day plan covering all of the exam topics. It will build your confidence and enable you to crack the Gold Standard exam, knowing that you have done all you can to prepare for the big day. This book provides concise explanations of important concepts in all 10 domains of the CISSP Common Body of Knowledge (CBK). Starting with Confidentiality, Integrity, and Availability, you will focus on classifying information and supporting assets. You will understand data handling requirements for sensitive information before gradually moving on to using secure design principles while implementing and managing engineering processes. You will understand the application of cryptography in communication security and prevent or mitigate strategies for network attacks. You will also learn security control requirements and how to assess their effectiveness. Finally, you will explore advanced topics such as automated and manual test result analysis and reporting methods. A complete mock test is included at the end to evaluate whether you're ready for the exam. This book is not a replacement for full study guides; instead, it builds on and reemphasizes concepts learned from them. Style and approach There are many overlapping concepts that are applicable to more than one security domain in the CISSP exam. Hence, the eight security domains are aligned in a logical order so as to cover the concepts in the most appropriate sequence in this guide. Each chapter provides an illustration in the form of a flow diagram at the start to supply an overall view of the concepts covered in that chapter. This will facilitate a bird's-eye view of the chapter contents and the core security concepts covered. You can refer to this book throughout while preparing for the test or most importantly systematically revise the eight domains on a day-by-day basis up to one month before the exam. Hence the chapters are divided into 21 convenient days.
