Learning ArcGIS Runtime SDK for .NET

Overview of this book

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.

MapView


In essence, MapView is a container for a map. It resides in the Esri.ArcGISRuntime.Controls namespace and is the most important control in ArcGIS Runtime because, without it, you can't view a map. It contains a series of properties, methods, and events just like any other .NET control. However, it's easy to get overwhelmed with all of the options, so let's dissect these options one by one and show some examples of use. Before we look at the details of this control, we first need to understand some mapping concepts.

Projections and coordinate systems

As a mapping developer, you really need to understand projections and coordinate systems. They have a huge impact not only on how data is displayed, but also on performance, usability, and other factors. Projections attempt to portray the surface of the earth on a flat surface. Coordinate systems use a three-dimensional sphere to define a location on the earth's surface.

There are many kinds of projections you can use and it really depends...
