Exercise outline
The goal of this exercise is to visualize multiple data sets on one map; in the end it should be possible to inspect both the input data and the output data of a volume model in one and the same map view. In this way different data sets can be compared at the same place and for the same modeling time step.

[TODO] Description of the exercise results
1. Create a new class named "DemoAppMapLayerProvider"
2. Add the following contents to this class:
using System.Collections.Generic;
using System.Linq;
using DelftTools.Shell.Gui;
using DeltaShell.Plugin.DemoApp.Models;
using SharpMap.Api.Layers;
using SharpMap.Layers;
namespace DeltaShell.Plugin.DemoApp
{
public class DemoAppMapLayerProvider : IMapLayerProvider
{
public ILayer CreateLayer(object data, object parentData)
{
var myModel = data as VolumeModel;
if (myModel != null)
{
return new GroupLayer(myModel.Name);
}
return null;
}
public bool CanCreateLayerFor(object data, object parentData)
{
return data is VolumeModel;
}
public IEnumerable<object> ChildLayerObjects(object data)
{
var myModel = data as VolumeModel;
if (myModel != null)
{
return myModel.DataItems.Select(d => d.Value);
}
return Enumerable.Empty<object>();
}
}
}
3. Register the map layer provider in the gui plugin class by adding the following code to DemoAppGuiPlugin:
public override IMapLayerProvider MapLayerProvider
{
get { return new DemoAppMapLayerProvider(); }
}
4. Run the application and create a volume model: a dialog to select a view for the volume model will automatically be opened Image Select Central map
