Create Tile Layers

Question

I show more than 5000 polylines on a Bing Map (Silverlight - C#). I want to us Tile layers. How can I create this layers from my current polylines?

 

Thanks!

Answer 1

You will need to create the tile layers on the server side. Here are two good places to start:

Thanks. When I open your first suggestion in VS2010 (And SQL server 2008R2 on same machine) and run, I get folllowing error when I check a radio button;

System.Data.SqlClient.SqlException was unhandled by user code

Answer 3

Ensure that the database is properly deployed and that the connection string has been updated in the application. Also ensure that there are no missing dll's.

Answer 4

Connection string is updated, database is succesfully deployed, and there are no missing dll's. (I think otherwise the application do not start up). Is it possible there is a problem with my locat setting? I'm from Belgium...

Answer 5

When I run the project at http://dataconnector.codeplex.com/ I get the same error...

Is it possible it don't work in .NET FRAMEWORK 4, or VS 2010?

Answer 6

It runs! The problem was my local settings...

This program is fantastic. Is there a way to support linestrings? In this configuration only polygons are supported...

Answer 7

Linestrings should be supported. They work in the demo app.

Answer 8

I don't think so... Only polygons and multipolygons work. For example in TilerenderEngine.cs you can see there is no support for polylines:

 

case Constants.ShapeType.Polygon:
                        Polygon polygon = shapes[i].SimpleBoundary;

                        points = GeospatialTools.CoordinateArrayToRelativePointFArray(polygon.ExteriorRing, _topLeftPixel, zoomMapWidth);
                        gr.FillPolygon(shapes[i].FillColor, points);
                        break;
                    case Constants.ShapeType.Multipolygon:
                        MultiPolygon multiPolygon = shapes[i].ComplexBoundary;

                        for (int j = 0; j < multiPolygon.Count; j++)
                        {
                            points = GeospatialTools.CoordinateArrayToRelativePointFArray(multiPolygon[j].ExteriorRing, _topLeftPixel, zoomMapWidth);
                            gr.FillPolygon(shapes[i].FillColor, points);
                        }
                        break;
                    //Do not render Points, MultiPoints, Polylines, Multilines or shapes with a null type for this demo
                    case Constants.ShapeType.Point:
                    case Constants.ShapeType.Multipoint:
                    case Constants.ShapeType.Polyline:

Answer 9

I've updated the code sample to support linestring and multilinestring.

Here is a simple Bing map dynamic layer module
