Map for WinForms - Create a Data Provider to Load Image Tiles from a Custom Source

This example shows how to implement a custom image tile provider. To do this, create a MapDataProviderBase class descendant and assign it to the ImageLayer.DataProvider property.

This example loads image tiles from a local cache. The image tiles are downloaded in advance from a public server with OpenStreetMap tiles. A list of alternative OpenStreetMap image tile providers is available here: OpenStreetMap: Tile usage policy.

Note: If you only need to change an URI to the location of OpenStreetMap image tiles, use the OpenStreetMapDataProvider and specify its TileUriTemplate property.
