Here.com maps are blank with Zoom 8 and above

I am using MapwinGis in Visual Foxpro 9 and am looking to switch to Here.com tile provider 10 since Microsoft is being deprecated. When I use Here.com, all works well if I’m zoomed out 7 or below. However, as I zoom in to 8 or above, the screen either freezes or eventually goes blank as it isn’t loading any tile updates. Am I missing a setting to allow this?

Hello.

I presume that you are adding a new TileProvider. A couple things to consider:

  • Are you specifying the zoom range that is supported by the service?
  • Are you using a unique provider ID, up in the custom range (greater than 1024)?
  • Is you map projection the same as that of the Provider?
  • It would be best if you could post the section of code where you set up or select the provider.

Thank you.
