[OpenLayers-Users] OpenLayers.Layer.OSM - Problems with definedresolutions

[Arnd Wippermann]

Hi,
 
in your serverResolutions array is one entry absent : 4891.9698095703125
 
it should be:
...,9783.939619140625, 4891.9698095703125, 2445.9849047851562,...
 
add the resolution and your problem should be solved.
 
Arnd

definedresolutions



Hello OpenLayers-Community,

 

at first i wanna thank you guys for the great work you are doing with
OpenLayers. It is a great piece of software and I really enjoy using it.
Right now I am faced with a problem regarding the  OpenLayers.Layer.OSM
object. I want to restrict the possible zoom levels of this layer and of the
map. So far this is possible by using the resolution and serverResolution
properties on the layer level. (I know it is also possible via the "zoomend"
event, but a definition over the possible resolutions looks for me the
cleanest way) But with that solution I run in two different kinds of
problems (both problems can be monitor by deploy the html file which is
attachted to this mail).


The first problem is that I got a strange coordinate behavior. Like you can
see in the attached html file, the lonlat-coordinates
(-9208448.7478114,13344939.50767) center me on the federal state of Saxony /
Germany. Normally I would expected this for the coordinates
(1481769,6634478). So what is OpenLayers doing here?

 

The second strange problem I encountered with the zoom behavior. When I
often zoom in and out, sometimes with the zoom out the map chooses a new
center point.  The new center point normally lies in the neighborhood of the
originally center point, but it is still a new center point. 


Maybe somebody also faced this kind of problem? It is a bug or it is
expected behavior? I am using OpenLayers 2.13.1.


Kind regards,


Jacob
