Hi, Below some code to show how you can accomplish your task. You have to use the projection sphericalMercator, to get your features at the right place.
Both your kml files are in projection EPSG:4326. OpenLayers is able to reproject vector data from EPSG:4326 (WGS84) to EPSG:900913 (sphericalMercator) and back without proj4js. You should also keep in mind, that a web application is not a desktop program. Loading your page results in downloading a kml file with 1.5 MB. I had have to wait endlessly until my firefox was willing to act again on mouse clicks.

So it could be WGS84. Now, there is kml file with WGS84 but lines aren't at place, where it should be. Why? I'm using the same projections, so it should be at right place or not? Ok, I can suppose, that I'm using bad projection and base layer has spherical mercator even I haven't written in my code 'sphericalMercator': true. It could be problem, but I tried fetch kml file with spherical mercator and it looks the same. Lines doesn't fit on base layer. Even If I use kml file with absolutely wrong projection like SJTSK (it is for the Czech republic only) it looks the same. I tried to use sphericalMercator: true but in that case I have center of map somewhere in Gulf of Guinea and I can't pan. I don't know, what I should do, because I thought that if I have kml file with the same projection as base layer, it will be ok. _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users _______________________________________________ Users mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/openlayers-users
