[OpenLayers-Users] OL Zoom Issue - Zoomed in very close, cannot not zoom out

[Marco Scheuble]

Hi Paul,

for me your coordinates looks strange.
If the projection is epsg: 4326, I think you have to take lat lon coords.

Instead of using the function map.zoomToExtent(), maybe you can use
map.zoomToMaxExtent()
