The SVG code is valid.
 
This map was created with an unknown SVG tool by Merikanto.
This map is not a real SVG file and is just a wrapper containing one or more raster graphics without vector coding.
Using SVG as just a wrapper is undesirable.
Note: This template should be used if the SVG file contains only raster graphics. If the SVG file contains both vector and raster graphics, then use {{BadSVG}}.
