Question

I use osmdroid to display a large image (4096×4096) that is split into tiles.

Now I want to set markers on the map based on the X and Y coordinates of the image, not latitude and longitude.

Is it possible to add markers on to map based on this data for example?

• X: 10, Y: 250
• X: 4000, Y: 0

Answer 1

I found the solution myself.

Microsoft has written a class (microsoft.mappoint.TileSystem) which is capable of doing exactly this.

Code example:

GeoPoint geoPoint = TileSystem.PixelXYToLatLong(
    10, // X
    250, // Y
    3, // Level of detail
    null // Reuse
);
