hi,
yes, but we need to create one own website, in that we need to integrate
the google map using javascript, for that we need to signup in google to get
API key,

here is the example code to include google map in our site:
<script src="http://maps.google.com/maps?file=api&v=1&key=ABQIAAAAeN_LhMOi4FsadGt6q2yJ qRRi-exo-90g1z9p2Z9OroAhcfs0axTr-W4zx9cE4tcCyp6mf1TJ2QiIAA" type="text/javascript"></script>

<script type="text/javascript">

function load() {
if (GBrowserIsCompatible()) {
var map = new GMap(document.getElementById("map"));
map.addControl(new GSmallMapControl());
map.addControl(new GMapTypeControl());
map.setCenter(new GLatLng(51.179045, -1.826752), 14);
var point = new GLatLng(51.17904, -1.826752);
var marker = new GMarker(point);
map.addOverlay(marker);
}
}
//]]>

</script>

<html>
<body>
<div id="map" style="width: 900px; height: 500px;"></div>
</body>
</html>

it will help you to create your own google map for ur site, after that
create a windows application, split the windows as per ur requirement,
add webbrowser to it, and

onloading of form give

webbrowser1.navigate("http://")//ur site url

blueIcon.infoWindowAnchor = new GPoint(9, 2);
var Icons=[];
Icons[0] = blueIcon;
var marker = new GMarker(point,Icons[0]);

var point = new GLatLng(51.17904, -1.826752);
var marker = new GMarker(point);
map.addOverlay(marker);

GEvent.addListener(map, 'click', function(overlay, point) {

if (overlay) {
map.removeOverlay(overlay);

} else if (point) {

map.recenterOrPanToLatLng(point);
var marker = new GMarker(point);
map.addOverlay(marker);
document.getElementById("latbox").value=point.y;
document.getElementById("lonbox").value=point.x;

}

});

}

hi,
The above code helps to remove the marker from map, i am searching for it for a long time, thanks

but i am facing a problem with icon,

Quote:

blueIcon.iconAnchor = new GPoint(9, 34);
blueIcon.image = "http://localhost:1661/map/Arrow.gif";
blueIcon.iconSize = new GSize(20, 34);
blueIcon.infoWindowAnchor = new GPoint(9, 2);
var Icons=[];
Icons[0] = blueIcon;
var marker = new GMarker(point,Icons[0]);

from the above code it generating the icon correctly only on load means only the first icon come as our wish.. how to change further icons also?

Thank you
G.Devaki

i am trying to place my marker over google map based on my values(longitude,latitude) from database

have any idea to implement this?

GDevakii · #13 (**permalink**) 08-11-2007, 01:43 AM

hi,
yes, we can implement it through XML, write the data's as XMl file and then
import the data's into Google map..

hi,
some issue with mapping:

There are several limitations to the Maps API:

* It doesn't provide a geocoding service; that is, you have to provide it with longitude and latitude. This means you need to rely on third-party geocoding tools to get longitude and latitude for an address.
* It doesn't include a routing or driving directions service.
* The Google Maps API key is restricted to generate maps only for URLs (website or a local host). You need to have a web server even for development.
* The key you receive is only valid for a single directory on your web site.
* It can be used for commercial purposes, but it should be available to end users for free.
* It can be used on a site that is password protected, but consumers should be able to sign up for a password without charge.
* Usage is not necessarily restricted, but if your site is getting more than 50,000 hits per day, you'd better contact Google.

Hi Mani,

Is there any way to integrate any third party reporting tools to google map windows application for showing out some sort of statistical report?

garunprasad · #18 (**permalink**) 08-14-2007, 11:45 AM

yes H2O,

I was also having the same query to be asked to Mani. But my second question was to show up 3D Modelling sort of reports.

I think Mani can answer to me as well.

Thanks in advance.

hi,
here is the sample code to draw polygon,

// ***** Use SVG to draw and fill polygons

_mSvgEnabled = true;
_mSvgForced = true;

//Load map
var map = new GMap(document.getElementById("map"));

var lineThickness = 1;
var points2 = [];
var polygons = new Array();
map.setCenter(new GLatLng(47.6719664015333, -122.4019448761567), 6);//11);

getPoints();
Gpolygons = new GPolygon(points ,"#698b22", 2, 0.7,"#b3ee3a", 0.5) ;
map.addOverlay(Gpolygons) ;

function getPoints() {
points2.push(new GLatLng(47.67207767885599, -122.40447521209717));
points2.push(new GLatLng(47.67047381359744, -122.40391731262207));
points2.push(new GLatLng(47.67051716195521, -122.40129947662353));
points2.push(new GLatLng(47.67204878081891, -122.40127801895141));

}

use all other's necessary code from above post
