Geocoding API javascript example

Enter any address below to locate it on the map

Using JavaScript

Example above is using JavaScript version of Geocoding API, so it is possible to call it through the browser. Source code is below:

document.write('<script src="http://maps.google.com/maps/api/js?sensor=false" type="text/javascript"></script>');
document.write('<div style="padding-bottom:10px;"><input type="text" name="address" value="O. J. Brochs g 16a, Bergen" style="width:400px;border:1px solid black"><input type="button" name="search" value="Geocode"></div>');
document.write('<div id="coords"></div>');
document.write('<div id="gmap" style="width:570px; height:500px;"></div>');
 
$(document).ready(function() {
 
	// Load google map
	var map = new google.maps.Map( document.getElementById("gmap"),  {
		center: new google.maps.LatLng(0,0),
		zoom: 3,
		mapTypeId: google.maps.MapTypeId.ROADMAP,
		panControl: false,
		streetViewControl: false,
		mapTypeControl: false
	});
 
 
	$('input[name=search]').click(function() {
 
		var geocoder = new google.maps.Geocoder(); 
		geocoder.geocode({
				address : $('input[name=address]').val(), 
				region: 'no' 
			},
		    function(results, status) {
		    	if (status.toLowerCase() == 'ok') {
					// Get center
					var coords = new google.maps.LatLng(
						results[0]['geometry']['location'].lat(),
						results[0]['geometry']['location'].lng()
					);
					$('#coords').html('Latitute: ' + coords.lat() + '    Longitude: ' + coords.lng() );
 
					map.setCenter(coords);
					map.setZoom(18);
 
					// Set marker also
					marker = new google.maps.Marker({
						position: coords, 
						map: map, 
						title: $('input[name=address]').val(),
					});
 
		    	}
			}
		);
	});
 
});

Using HTTP

Another way to use Geocoding API is though HTTP GET request. This way is more suitable to beused in PHP scripts. All is needed is to make request to the URl below, substituting the real address.

http://maps.googleapis.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA&sensor=true_or_false

Response is JSON encoded object, you can see more sample at Google Geocoding API help page

It is written in PHP and uses MySQL as database backend, client part uses jQuery for AJAX queries. Dictionaries are indexed in admin part for quick access. By now searches through 2 mil words takes about half of the second. Interface is as simple as possible and was inspired by GoldenDict. For sample usage it contains Russian-English and English-Russian dictionary(Universal, Computer, Oil, Gas...)

Try to access it here http://a32.me/other/dict/

Comments are welcome. If I have more time and some interest to it, will release it open-source .There might be interest to use it in intranet environment.

Additional free dictionaries can be found here:

Visual Petri Net Plus (VPNP)  was thesis of my diploma work at Technical University of Moldova(2000-2002). It is Petri Net designer, simulator and calculator. It has nice graphical engine that help to draw Petri net quite easy.

Theory of Petri Nets is intresting, you can find a lot of information on the net.

My work was to do graphical designer, save/load and simulation.

Tools used: Delphi 5.

Designer interface

Interface was inspired by standard Delphi interface.

Element property editor

Looks like standard delphi Object Inspector, but it is not. It is custom written.

Sample nets drawings

Simulation

This is most attractive part in this project.

Simulation control panel

Allows to add graphs to see progress during simulation.

Live simulation

It was recorded from real example. Flash plug-in required to view.

Downloads

Download executable and some sample to play with.

Source codes are available on request.
