When I use WMS layer, the layer is shifted differently in different zoom levels.

Example:[[BR]]

  • I use cadastral map for Czech rep. and I draw a building according to WMS layer ([http://www.kyblsoft.cz/data/merkaartor-bug-zoom4.png See image 1])[[BR]]
  • When I scroll out one zoom level, it is still ok ([http://www.kyblsoft.cz/data/merkaartor-bug-zoom3.png See image 2])[[BR]]
  • But in next zoom level is layer shifted from drawed building ([http://www.kyblsoft.cz/data/merkaartor-bug-zoom2.png See image 3]) and the next level again but more ([http://www.kyblsoft.cz/data/merkaartor-bug-zoom1.png See image 4]). In this level, building is shifted by several meters from place in map zoomed in and even shift has other direction than in image 3 (!).

However, when I use JOSM instead, the same map layer is always in the same place, and, unfortunately, the places of buildings in layer in JOSM are not equivalent to any zoom level in Merkaartor. ([http://www.kyblsoft.cz/data/merkaartor-bug-josm.png See the same place in JOSM]) So I can't do precise maps with Merkaartor.

I use Merkaartor v0.12 for Linux but the same issue is in v0.13 rc2 for Windows.

The address of WMS is:[[BR]]
Server: wms.cuzk.cz[[BR]]
Main path: /wms.asp?service=WMS&VERSION=1.1.1&REQUEST=GetMap[[BR]]
Layers: kn,def_budovy[[BR]]
Projection: EPSG:4326[[BR]]
Styles: ,[[BR]]
Image format: image/png

Please check this bug, I very like Merkaartor (thank for it) but with this issue I can't do good maps. Thanks.
