Hi. Is it possible to implement a custom map provider of some geospatial objects? For example, of geometry (wkt or wkb).

I mean, I have some geospatial data source and I can show the data using SqlGeospatialDataReader. But it loads all the shapes (polygons) independently of zoom level and position. I've tried to implement a custom map provider. But the GetTile method of TiledMapSource returns Uri to the image, not the custom data. Doesn't it? 

Thanks.

Hello Alex,

No, you can't create map provider which will use geospatial objects.

I would like to recommend you using of the Dynamic layer instead of Information layer. It allows decreasing the quantity of objects on the map at the same time depending on the zoom level and viewport. For more information please see the Using dynamic layer documentation topic:
