Image Overlay Module - Large Images are Incorrectly Positioned Vertically


Image Overlay Module (ImageOverlay)

When an image is stretched over a large area it will be south of the actual location in the northern hemisphere and north of the actual location in the southern hemisphere.

See Patch 17888 for fix.

This is to be expected given the Mercator projection of the map which stretches pixel coordinates. The image overlay module is meant for images that cover smaller areas, like building floor plans, not country size images.

I disagree. The overlay module should interpret and project geographic coordinates correctly regardless of the area size. Frankly, it's a bug. Please see the my patch for details which handles "country size images" correctly.
