[OpenLayers-Users] Adjusting Zoom Level Based on Points

[Sveen Atle Frenvik (Geomatikk IKT)]

I guess something along these lines should do the trick (not tested)


//create map etc..


var vectorLayer = new OpenLayers.Layer.Vector("vectors");
map.addLayer(vectorLayer);

var draw = new OpenLayers.Control.DrawFeature(vectorLayer,OpenLayers.Handler.Path);

map.addControl(draw);

draw.events.register("featureadded",this,function(feature){map.zoomToExtent(feature.geometry.getBounds());});

	if the points are in your vector layer, you can get the extent of that layer and set zoom accordingly

		As you're going through the points, keep track of the min/max x and y, then use those values to set the extent (the boundaries). 

		While you can do this in Javascript, we ended up doing that calculation in the server-side call that got the points, and sending it over with the json that used to populate the array of points.

			Hi,
			     I want to draw the line (route using x,y coordinate points) over the map as vector layer. After route drawn on map, i want to adjust the zoom level to show the complete route. How can i do this? Is there any direct way to do this? If not how to do using math calculations?
