OpenSpace. GridProjection

Enables transformation from WGS84 to British National Grid and from British National Grid to WGS84.

Example

var gridProjection = new OpenSpace.GridProjection();
var lonlat = new OpenLayers.LonLat(-0.15567, 54.4544);
var mapPoint = gridProjection.getMapPointFromLonLat(lonlat);
