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.

Converting coordinates


When you work with layers in one coordinate system and need to convert them to another coordinate system, the ConvertCoordinate static class is your friend. With this class, you can convert back and forth between the Global Area Reference System (GARS) of National Geospatial-Intelligence Agency (NGA), latitude/longitude, Military Grid Reference System (MGRS), U. S. National Grid (USNG), and Universe Transverse Mercator (UTM). GARS and MGRS are particularly relevant to the military. For more information on GARS, UTM, MGRS, and USNG, navigate to http://earth-info.nga.mil/GandG/coordsys/grids/referencesys.html.

Here is an example of converting a latitude/longitude to MGRS:

MapPoint mapPointLatLon = new MapPoint(0, 0, 
    SpatialReferences.Wgs84);
string coord = ConvertCoordinate.ToMgrs(mapPointLatLon,   
    MgrsConversionMode.Automatic, 2, false, false);

The resulting string will contain a value that looks like this: 31NAA6600. Another example illustrates converting...
