Geocoding

This is the process by which an address is located. Once constructed an instance of the Geocoder can be reused within an application.

function init() { 
    var map = new MapDS.Maps.Map( "map" ); 
    var g = new MapDS.Maps.Geocoder(); 
    var address = new MapDS.Address( null, null, "2065" ); 
    // make call to server for geocode 
    g.getLocations( address, function(result) { 
        if (result.Code===1) { 
            // build a marker to represent the geocode 
            var m = new MapDS.Maps.Marker( 
                new MapDS.LatLng( result.Locations[0].Position.Latitude, result.Locations[0].Position.Longitude ) 
            ); 
            var html = '<p>'; 
            html += ( result.Locations[0].AddressLine ? result.Locations[0].AddressLine + ', ' : '' ); 
            html += ( result.Locations[0].Locality ? result.Locations[0].Locality + ', ' : '' ); 
            html += ( result.Locations[0].PostalCode ? result.Locations[0].PostalCode + ', ' : '' ); 
            html += ( result.Locations[0].Region ? result.Locations[0].Region + ', ' : '' ); 
            html += ( result.Locations[0].Country ? result.Locations[0].Country : '' ); 
            html += '</p>'; 
            m.setPopupContent( html ); 
            // add a marker for the geocode 
            map.addOverlay(m); 
            // zoom in to geocode 
            map.setCentre( m.getPoint(), 15 ); 
        } 
    });
} 
// load it up 
window.onload = init;

Directions

The ability to calculate directions between two or more points is available using the Directions object. If the object is created using a Map as the first arugment then a polyline will be drawn on the map. If the second parameter is set to an DOM element then a list of instructions will be displayed.

function init() { 
    var map = new MapDS.Maps.Map( "map" ); 
    var d = new MapDS.Maps.Directions( map, 'directions' ); 
    var waypoints = []; 
    waypoints.push( new MapDS.LatLng(-33.831958,151.186129) ); 
    waypoints.push( new MapDS.LatLng(-33.739288,151.211439) ); 
    d.buildFromWaypoints( waypoints ); 
} 
 
window.onload = init;

Find

The QuickMap^® Map control provides a method for performing a feature search by calling the MapData Sciences servers.

For testing, developers have access to a limited feature set of POIs (Points Of Interest). Talk to us to gain access to over 20 categories and 52,000 predefined "sets" of locations eg fast food outlets, ATM's, Schools.

function init() { 
    var map = new MapDS.Maps.Map( "map", { zoom:9, centre:new MapDS.LatLng( -33.82011, 151.211626 ) } ); 
    // build find options, centre point and 2km radius 
    var fo = new MapDS.Maps.FindOptions( map.getCentre(), 2000 ); 
    // make call to server for items 
    map.Find( fo, function(results) { 
        for (var i=0; i<results.features.length; i++) { 
            var m = new MapDS.Maps.Marker( results.features[i].position ); 
            var html = '<ul>'; 
            for ( var prop in results.features[i].properties ) { 
                html += ( results.features[i].properties[prop] ? '<li>'+prop+':'+results.features[i].properties[prop]+'</li>' : '' ); 
            } 
            html += '</ul>'; 
            m.setPopupContent( html ); 
            map.addOverlay( m ); 
        } 
        map.loadBestView(); 
    }); 
} 
      
window.onload = init;
