  • 1.  "No overlay dataset available" error

    Posted 03-20-2023 11:30

    Hi

    A client sent me a WMS URL they want to use in MapXtreme which is embedded in our product.  When I zoom to the area for the WMS data, the app crashes.  Using the same WMS in MI Pro I get the error 'The server issue the following exception: No overlay dataset available'.  MI Pro does not crash but I wondered if the problem is the same.

    What does 'No overlay dataset available' mean and what should the WMS provide?

    I can load the WMS in QGIS.

    These are the capablities - https://map.staffordshire.gov.uk/PRoW/wms.exe?service=WMS&version=1.3.0&request=GetCapabilities

    Regards

    Chris

    Chris,

    Seems to be a zoom layering setting somewhere (probably at the Cadcorp end) if you zoom in enough in Pro you do get the data.  I would attach a screenshot but the page won't let me 

    Regards,

    Hi Nick

    You were right.  I loaded another layer and zoomed to the area covered by the WMS before adding it.  I could then see the data I wanted and, as expected, got the 'No overlay dataset available' warning with I zoomed out far enough.

    Thanks

    Chris
