The following code produces a Map with a point and some text added:

test = GeoGraphics[{PointSize[Large], Black, Point[{3.5, 52}], 
   Text["Text on a Map", GeoPosition[{52, 3.5}], {0, 1}, {0, 1}]}, 
  Frame -> True, GeoRange -> {{50, 56}, {0, 7}}, 
  GeoProjection -> "Equirectangular", ImageSize -> 1000]

This picture is transported to a webpage by:

CloudExport[test, "HTML", Permissions -> "Public"]

The result is a lower quality of the map and a much lower quality of the "text" at the point in the map.

Is there a way to improve picture quality when cloud-deployed. Is it possible to put the overlay of text in a svg file and use the bitmap as a background. This would help when a web-browser user zooms in. Any other suggestion to improve image quality are very welcome. btw maps on the desktop look much smoother.
