I'm wondering what the best strategy to position a map that has two points, using OpenLayers is. At the moment, my approach is to calculate the mid-point of the two points, and to zoom the map to that mid-point using the following approach:
var centerPoint = new OpenLayers.LonLat(lon, lat); map.setCenter(centerPoint, zoomLevel);
However, this is not ideal as I don't know what the
zoomLevel should be, so sometimes although the map is centered, the points are not visible.
Is there a better approach to dynamically position the map?
