[OpenLayers-Users] combine 2 different projections map data

[Aypes2]

Hi all, 

I think I have solved the problem. The broken line may be due to the use of
"gutter" in OL app. Without using it, the no. of broken lines on the map are
greatly reduced but some labels are "broken". Now I work on the scale ratio
problem. 
Thanks all.
