EPSG:31467 Projection

[Margret]

Hi,

is there an out of the box solution for the RadMap to use the EPSG:31467 map projection?

So far we use a custom OSM Source but now a new customer wants to use his own tile provider using EPSG:31467.

We already know how to use our own provider but are there built in functions to transform the data for the override in GetTile( int tileLevel, int tilePositionX, int tilePositionY ) for example?

 

Thanks, 

Margret

Hello Margret,

There is no built-in support for the EPSG:31467 projection in the RadMap control. However, you can use several approaches to display your tiles.

• The first and the most convenient when it comes to RadMap usage would be to convert to the standard Mercator projection used by the map.
• Another way to go is to create a custom coordinated converter by implementing the ICoordinateConverter interface, and then assign it to the CoordinateConverter property of the shape file reader object (for example the AsyncShapeFileReader). Additionally, you can try one of the built-in coordinate converters and see if they would help for the EPSG:31467 projection.
• The last approach that I can suggest would be to implement a custom tiles provider and try to get the tiles expected by the map there. 

In any case, the map doesn't contain helper methods that helps converting from the EPSG:31467 projection.
