Google Map As A Vector Map
Solution 1:
As suggested in my comment, you can check how to style the map:
https://developers.google.com/maps/documentation/javascript/styling
This can help you understand how it works, and eventually let you build your own:
Regarding Fusion Tables, once you find the appropriate data set (there are many, some are incomplete, more or less, and the level of geometry details can vary from one set to another), you can download it as a CSV, and import it to your DB. From there, you can query your DB and create polygons for each country. I will update my answer later with some code to help you get started.
Edit: Here is a data set I used for one of my projects. Maybe it can help you. It only holds the fields I was interested in, but has random colors associated with each country. http://www.sendspace.com/file/plgku3https://www.dropbox.com/s/7o5y26gfim1asf0/gmaps_countries.sql?dl=1https://drive.google.com/file/d/1Qi4TOA3YUh3bL8SuIWbjA0B0QFIrA1ti/view?usp=sharing
Edit 2: Here is the JavaScript:
var g = google.maps;
var countries = [];
functionjsonCountries() {
$.ajax({
url : 'get_countries.php',
cache : true,
dataType : 'json',
async : true,
success : function(data) {
if (data) {
$.each(data, function(id,country) {
var countryCoords;
var ca;
var co;
if ('multi'in country) {
var ccArray = [];
for (var t in country['xml']['Polygon']) {
countryCoords = [];
co = country['xml']['Polygon'][t]['outerBoundaryIs']['LinearRing']['coordinates'].split(' ');
for (var i in co) {
ca = co[i].split(',');
countryCoords.push(new g.LatLng(ca[1], ca[0]));
}
ccArray.push(countryCoords);
}
createCountry(ccArray,country);
} else {
countryCoords = [];
co = country['xml']['outerBoundaryIs']['LinearRing']['coordinates'].split(' ');
for (var j in co) {
ca = co[j].split(',');
countryCoords.push(new g.LatLng(ca[1], ca[0]));
}
createCountry(countryCoords,country);
}
});
toggleCountries();
}
}
});
}
functioncreateCountry(coords, country) {
var currentCountry = new g.Polygon({
paths: coords,
strokeColor: 'white',
strokeOpacity: 1,
strokeWeight: 1,
fillColor: country['color'],
fillOpacity: .6
});
countries.push(currentCountry);
}
functiontoggleCountries() {
for (var i=0; i<countries.length; i++) {
if (countries[i].getMap() !== null) {
countries[i].setMap(null);
} else {
countries[i].setMap(map);
}
}
}
And here is get_countries.php:
$results = array();
$sql = "SELECT * from gmaps_countries";
$result = $db->query($sql) ordie($db->error);
while ($obj = $result->fetch_object()) {
$obj->xml = simplexml_load_string($obj->geometry);
$obj->geometry = '';
foreach ($obj->xml->Polygon as$value) {
$obj->multi = 'multigeo';
}
$results[] = $obj;
}
echo json_encode($results);
Just call jsonCountries()
when you need. Hope this helps!
