How to: Connect a Map Control to the OpenStreetMap Geocode Service

• Nov 13, 2018

This example demonstrates how to add an image layer displaying map tiles from the OSM service and an information layer that searches for a place on the map using the OSM search service. It uses the following classes:

Class	Description
ImageLayer	Displays map images obtained from map image data providers.
OpenStreetMapDataProvider	The class that loads map images from a web resource that provides data in the OpenStreetMap format.
InformationLayer	A layer that is used to display additional information above the map.
OsmGeocodeDataProvider	Provides the capability to obtain geocode data from the Open Street Map service.

MainForm.cs

private void OnFormLoad(object sender, EventArgs e) {
    mapControl.Layers.AddRange(new LayerBase[] {
        new ImageLayer {
            DataProvider = new OpenStreetMapDataProvider() {
                TileUriTemplate = "YOUR_TILE_SERVICE.com/{1}/{2}/{3}"
            }
        },
        new InformationLayer {
            DataProvider = new OsmGeocodeDataProvider()
        }
    });
}

MainForm.vb

Private Sub OnFormLoad(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
    mapControl.Layers.AddRange(New LayerBase() { _
        New ImageLayer With { _
            .DataProvider = New OpenStreetMapDataProvider() With {.TileUriTemplate = "YOUR_TILE_SERVICE.com/{1}/{2}/{3}"} _
        }, _
        _
        New InformationLayer With {.DataProvider = New OsmGeocodeDataProvider()} _
    })
End Sub
