More info

This map has a very fast zoom. It doesn't help load tiles faster. Load speed depends on your internet speed.

Known Bugs

Zoom with mouse wheel doesn't work in Safari, Opera and Konqueror.

Snap

There is a problem with smooth zoom that can't be resolved.
If images are NOT displayed with original width and height, the images are NOT very clear.
Examples
Original size: 256px Original size: 240px Original size: 270px 4 scaled images

Autosnap

If you stop zooming, the map will snap to a zoomlevel that guaranties the best images quality. The problem with this, is that the user thinks the map does something he doesn't want.

Snap strategies

Stratgie Description Problem
Snap timeingAt the moment the map snaps 300ms after the the last zoom action The user does not expect that behaviour
Snap directionIf the user zooms IN it would be better to snap to the next higher zoomlevel. If the user zooms OUT the map should snap zo the next lower zoomlevel The map will be resized by factor 2 in worst case
Animated snap If the user stops zooming, the map should start an automated zoom to the next zoom level. (like google) The user feels not to have control over zoom
Manual snap The user hit the [enter] key to snap Only for expirienced users
Vector data It would be possible to build the map with vector data using SVG Too much data, server too slow, client too slow
bilinear resize in browser If browsers learn to zoom better, the problem is solved Browsers like firefox, explorer can't do that
