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.

Geometric objects


In order to add any kind of geometry, such as a line, circle, or 3D fence, we must get down to the basics and discuss geometry in enough detail so that you are able to add more content to your map or scene, either by constructing the geometry in code or allowing the user to interactively create the geometry on the map or scene. (We will discuss interactive editing in Chapter 9, Editing Features.) In this section, we're going to consider the following object diagram and discuss each type of geometry:

All objects in this section will come from Esri.ArcGISRuntime.Geometry.

Immutability

All of these geometries are immutable, which means that once you create them, you can't change them. However, all of these geometries can be created and modified with their respective builder classes. We will discuss the builder classes after we've introduced these geometries.

Geometry object

The Geometry object is an abstract class that defines a geometric shape, which means all subclasses inherit...
