Does this look like it should work? I'm wanting to generate directions from one latitude/longitude to another latitude/longitude.
var dirMap = new GMap2($("#dirMap").get(0));
var wp = new Array(2);
wp[0] = new GLatLng(35.742149,139.337218);
wp[1] = new GLatLng(35.735347,139.328485);
var marker = new GMarker(wp[1]);
dirMap.addOverlay(marker);
dirMap.setCenter(wp[0], 12);
dirMap.setUIToDefault();
// load directions
directions = new GDirections(dirMap);
directions.load("from: Waypoint1#21.742149,100.337218 to: Waypoint2#15.740815,100.3267");
The map loads fine, but the directions don't come in. I've tried it this way too:
var dirMap = new GMap2($("#dirMap").get(0));
var wp = new Array(2);
wp[0] = new GLatLng(32.742149,119.337218);
wp[1] = new GLatLng(32.735347,119.328485);
var marker = new GMarker(wp[1]);
dirMap.addOverlay(marker);
dirMap.setCenter(wp[0], 12);
dirMap.setUIToDefault();
// load directions
directions = new GDirections(dirMap);
directions.loadFromWaypoints(wp);
Same thing... map but no directions. Any help is greatly appreciated, thank you in advance!
I can't see anything obvious at first glance at your code, so my first guess is a failure coming back in for the GDirections request (I am also assuming you have checked the javascript error log for any errors, Tools/Error Console if you haven't already done this).
I suggest you add an error handler for your GDirections object, this will give you some indication what is happening with your request:
GEvent.addListener(directions, "error", handleErrors);
and in the handleErrors callback have a look in:
directions.getStatus().code
Compare with the Geo Status Codes.
EDIT: Ok, I just tried out your code here and it works perfectly. I can only assume that there is some other problem on your page that is causing the issue. Can you post a link in the question so we can check it out ?
Checking the status (604) I got when I tried in the Google Maps API Reference says:
The GDirections object could not
compute directions between the points
mentioned in the query. This is
usually because there is no route
available between the two points, or
because we do not have data for
routing in that region.
and this is the code I used (slightly modified):
$(function ()
{
if (GBrowserIsCompatible())
{
var wp = [new GLatLng(35.742149,139.337218), new GLatLng(35.735347,139.328485)];
var map = new GMap2(document.getElementById('map-canvas'));
map.setCenter(wp[0], 12);
map.setUIToDefault();
var marker = new GMarker(wp[1]);
map.addOverlay(marker);
var directions = new GDirections(map);
GEvent.addListener(
directions,
'error',
function ()
{
console.log(directions.getStatus().code);
}
);
directions.load('from: Waypoint1#21.742149,100.337218 to: Waypoint2#15.740815,100.3267');
}
});

I want to do something like the following line of code but using HERE javascript API
var polygonLayer = new Microsoft.Maps.Layer("PolygonLayer");
map.layers.insert(polygonLayer);
I read the documentation but I am not sure if my code is correct. This is my code:
var polygonLayer = new H.map.layer.Layer("PolygonLayer");
map.addLayer(polygonLayer);
as title suggest, create Feature and add it to already created vector layer. I am fetching GeoJSON from server and trying to somehow add to vector layer but I can't get it to work... So basically I am asking how to get Feature element from my GeoJSON, so I can add it to vector layer.
What I currently have..
This is my GeoJSON fetched from server :
{"type":"MultiPolygon","coordinates":[[[[20.5629940201429,48.9488601183337],[20.5630121528311,48.9489447276126],[20.563289335522,48.9489141101973],[20.563260061873,48.9488286413488],[20.5629940201429,48.9488601183337]]]]}
next I have addVector function in JavaScript where I'm trying to the magic.(variable GeoJS is GeoJSON fetched from server)
function addVector(geoJS){
var feature = new OpenLayers.Feature.Vector( new OpenLayers.Geometry.MultiPolygon(geoJS) );
vector = new OpenLayers.Layer.Vector("Magic");
map.addLayer(vector);
vector.addFeatures([feature]);
}
and yep I know that second line where I creating feature is wrong, but i cant make it right so i guess id doesn't matter what I write there for now...
I tried it with var feature = new OpenLayers.Feature.Vector(new OpenLayers.Geometry.Point(-70.702451, 42.374473); and it worked position on the map was not where I want it to be but I know that i have to do something with projection... It just doesn't matter now.
and btw I have this
vector = new OpenLayers.Layer.Vector("GeoJSON",
{
projection : "EPSG:4326",
onFeatureInsert : postIns,
strategies : [new OpenLayers.Strategy.Fixed()],
protocol : new OpenLayers.Protocol.HTTP({
url: "test.php",
format: new OpenLayers.Format.GeoJSON()
})
});
And this works, position is where I want it, its perfect except it only works when I make request on my domain, and server I try to reach is on another(I know I can set headers and it would work) but I don't want to do it this way.
So basically I am asking how to get Feature from my GeoJSON. I am really new to OpenLayers so I'm sorry if I asking something obvious.
To use a simplified version of the official example:
var inputGeoJson = '...some-GeoJSON-here...';
var geojson_format = new OpenLayers.Format.GeoJSON();
var vector_layer = new OpenLayers.Layer.Vector();
map.addLayer(vector_layer);
vector_layer.addFeatures(geojson_format.read(inputGeoJson));
You can find more details in the GeoJSON class documentation.
I need help with a code from my work, it is a map (google,maps) with a kml, it is updated every 4 minutes time to the script extract the information to the bd, my problem is with the map. It doesn't refresh.
the map is here: 190.216.202.35/control/patios.html
and the kml is here: 190.216.202.35/control/refresh.kml
the map call a kml
all the code is correct but the page dont refresh the points not move until y "F5" the page
sorry for my English but I really need help
I have this but Is Not Enough
var map = new google.maps.Map(document.getElementById('map-canvas'), mapOptions);
var kmlLayerOptions = {map:map, preserveViewport:true}; //map:display kml layer on created map object called "map"; preserveViewport: preserve maps options
var kml = new google.maps.KmlLayer("http://190.216.202.35/control/refresh.kml?dummy="+(new Date()).getTime(), kmlLayerOptions);}
google.maps.event.addDomListener(window, 'load', initialize);
var refreshMilliseconds = 3000;
var options = {
frequency : refreshMilliseconds,
enableHighAccuracy : true
};
try to implement the code code in function watchUserLocation(),i am trying to upadte for every 3 sec
What I'm trying to do is to change the default icon that is displayed when you set the Clustering Configuration for a Bing Map using the Bing Maps Ajax Control 6.3.
I have a function that loads a Bing Map like this:
function getMap() {
map = new VEMap('map_canvas');
map.SetDashboardSize(VEDashboardSize.Tiny);
var latLong = new VELatLong(21.983801, -101.557617);
map.LoadMap();
var customPin = '<div style="position:relative; left:-10px;top:-20px;"><img src="../Content/images/icons/pin1.png" style="width:40px; height:40px"></div>';
icon.CustomHTML = custom;
var options = new VEClusteringOptions(icon, null);
map.GetShapeLayerByIndex(0).SetClusteringConfiguration(VEClusteringType.Grid, options);
map.SetCenterAndZoom(latLong, 6);
map.SetMouseWheelZoomToCenter(false);
map.EnableShapeDisplayThreshold(true);
map.AttachEvent("onclick", singleMouseHandler);
map.AttachEvent("ondoubleclick", doubleClickMouseHandler);
}
But so far it keeps displaying the same default icon. What am I missing here?
Another thing I was wondering is if there's a way to change the custom icon if a pin in the cluster changes, like if I have 5 green Push Pins but one of them is updated to be a blue Push Pin, is there a way to change the icon that represents that cluster?
I found the reason my approach wasn't working, I keep thinking I'm dealing with classes with constructors that receive parameters, which in this case the VEClusteringOptions class doesn't receive parameters in its constructor. I had to set the Icon property separately:
function getMap() {
map = new VEMap('map_canvas');
map.SetDashboardSize(VEDashboardSize.Tiny);
var latLong = new VELatLong(21.983801, -101.557617);
map.LoadMap();
var customPin = '<div style="position:relative; left:-10px;top:-20px;"><img src="../Content/images/icons/pin1.png" style="width:40px; height:40px"></div>';
icon.CustomHTML = custom;
var options = new VEClusteringOptions();
options.Icon = icon; // here's the "big" difference
map.GetShapeLayerByIndex(0).SetClusteringConfiguration(VEClusteringType.Grid, options);
map.SetCenterAndZoom(latLong, 6);
map.SetMouseWheelZoomToCenter(false);
map.EnableShapeDisplayThreshold(true);
map.AttachEvent("onclick", singleMouseHandler);
map.AttachEvent("ondoubleclick", doubleClickMouseHandler);
}
Now my custom cluster icons are being loaded great, I need to get used to more to the concept of property in the future.
I did the development long time ago for our company site. Did you try the interactive SDK available here?

I have added the reference for pushpin development

How do I show a local image for a GMarker? I am using v2. Code sample
var blueIcon = new GIcon(G_DEFAULT_ICON);
blueIcon.image = '/Images/marker/mr.png';
markerOptions = { icon: blueIcon };
map.setCenter(point, 3);
var marker = new GMarker(point, markerOptions);
Its not working...
What's local to the map page is the Google Maps site itself, so if you want to use an image from your site, you have to provide the full URL for it.
If you haven't seen the v2 docs, here is a link:
http://code.google.com/apis/maps/documentation/javascript/v2/overlays.html#Custom_Icons
Also, are you actually adding it to the map, or have you omitted that from your code?
Here is a full example:
