Make Polygon geofence in asp.net HTML
Using this way we can make the Polygon on Google Map, but you have to pass the geofence array of Latitude and longitude. you can pass this array from asp.net using ClientScript.RegisterArrayDeclaration method and pass the LatLng string in below format
ClientScript.RegisterArrayDeclaration("geo", "'38.97441,-77.013798','38.972257,-77.011043','38.97011,-77.008298','38.96966,-77.007743',");
The output of this array will be like
<scri pt type="text/ javascript">
//<![CDATA[
var geo = new Array('38.97441,-77.013798','38.972257,-77.011043','38.97011,-77.008298');
//]]>
</sc ript>
function initialize() {
var myLatlng = new google.maps.LatLng(latitude[0], longitude[0]);
var myOptions = {
zoom: parseInt(zoomsize[0]),
center: myLatlng,
mapTypeId: google.maps.MapTypeId.ROADMAP
}
map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);
var polys = [];
var labels = [];
var pts = [];
var pts1 = [];
var polys1 = [];
for (var i = 0; i < geo.length; i++) {
var arg = geo[i].split(",");
pts[i] = new google.maps.LatLng(parseFloat(arg[0]),
parseFloat(arg[1]));
}
var myTrip = pts;
var flightPath = new google.maps.Polygon({
path: myTrip,
strokeColor: "#FF0000",
strokeOpacity: 1,
strokeWeight: 1,
fillColor: "#ffffff",
fillOpacity: 0
});
flightPath.setMap(map);
}
