[OpenLayers-Users] Display Coordinates

[Arnd Wippermann]

you have to set your variable mercator to the right projection.
from kml-pointtrack.js.php:

var mercator = new OpenLayers.Projection("EPSG:4326"); <!-- WGS84 -->
var geographic = new OpenLayers.Projection("EPSG:4326"); <!-- WGS84 -->
it should be 
var mercator = new OpenLayers.Projection("EPSG:900913");

Betreff: Re: [OpenLayers-Users] Display Coordinates


I was missing an "else if" on my code and the mercator was always setted to
EPSG:900913, now it seems to work but the wgs-84 version dosen't center the
map on the desired position:
    center: new OpenLayers.LonLat(15.4386126995087,
38.2423138618469).transform(geographic, mercator)
why?

Many thanks

Okay, you have added displayProjection.

So looking at the formatOutput function, I see.

lonLat now comes into the function as lat/lon in 4326.

you convert to mercator

However lonLat.transform changes lonLat.



try

var geoCoor = lonLat.clone();

   geoCoor.transform(geographic, mercator);

var lat = lonLat.lat;

var long = lonLat.lon;

var ns = OpenLayers.Util.getFormattedLonLat(lat);

var ew = OpenLayers.Util.getFormattedLonLat(long,'lon');

return '<div style=\"color: green; font-size: 14px; font-weight: bold; 

background-color: white; width: 700px; text-align: left;\">Coordinate: ' 

+ ns + ', ' + ew + ' (' + (Math.round(geoCoor.lat * 10000) / 10000) + ', 

' + (Math.round(geoCoor.lon * 10000) / 10000) + ')' + '</div>';

}



Get used to using firebug or similar. It makes it easy to see what is 

going on. Put breakpoint in formatOutput and then watch the values.
