Google static maps with directions

问题

I have in my project list of generated places with mini maps. There should be 2 points on the map and colored road direction between this two points.

it should looks somehow like this:

This should be static image, because there will be many such pictures with different directions on the page. But as I see, Google Static map didn't allow to draw such image. There can be only direct line between two points, like this:

But I need direction on it...

I decided to use static map, because in my web application I receive coordinates of those 2 points, and it's easy to put it as variables in my PHP template if I use static maps. But is it possible to receive direction as static image in same way?

I have found few solution with JavaScript API, but didn't find how to draw static image as I need...

回答1:

You can do it in two steps.

Execute directions request from the PHP code to get the encoded polyline
Use encoded polyline from step 1 with static maps

E.g.

https://maps.googleapis.com/maps/api/directions/json?origin=Grodno&destination=Minsk&mode=driving&key=YOUR_API_KEY

This will return encoded polyline in routes[0]->overview_polyline->points

Now use the polyline in static map:

I have created a small utility function for my website that does exactly what you need : https://github.com/bdupiol/php-google-static-map-directions

Given an origin, a destination and a array of waypoints (if needed), it gives you a clean Google Static Maps URL with driving path rendered between those points, and sets proper markers.

index.php

<?php

include "static-map-direction.php";

$origin = "45.291002,-0.868131";
$destination = "44.683159,-0.405704";
$waypoints = array(
    "44.8765065,-0.4444849",
    "44.8843778,-0.1368667"
  );

$map_url = getStaticGmapURLForDirection($origin, $destination, $waypoints);

echo '<img src="'.$map_url.'"/>';

static-map-direction.php

<?php

function getStaticGmapURLForDirection($origin, $destination, $waypoints, $size = "500x500") {
    $markers = array();
    $waypoints_labels = array("A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K");
    $waypoints_label_iter = 0;

    $markers[] = "markers=color:green" . urlencode("|") . "label:" . urlencode($waypoints_labels[$waypoints_label_iter++] . '|' . $origin);
    foreach ($waypoints as $waypoint) {
        $markers[] = "markers=color:blue" . urlencode("|") . "label:" . urlencode($waypoints_labels[$waypoints_label_iter++] . '|' . $waypoint);
    }
    $markers[] = "markers=color:red" . urlencode("|") . "label:" . urlencode($waypoints_labels[$waypoints_label_iter] . '|' . $destination);

    $url = "https://maps.googleapis.com/maps/api/directions/json?origin=$origin&destination=$destination&waypoints=" . implode($waypoints, '|');
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, false);
    $result = curl_exec($ch);
    curl_close($ch);
    $googleDirection = json_decode($result, true);

    $polyline = urlencode($googleDirection['routes'][0]['overview_polyline']['points']);
    $markers = implode($markers, '&');

    return "https://maps.googleapis.com/maps/api/staticmap?size=$size&maptype=roadmap&path=enc:$polyline&$markers";
}

I took Bedu33 logic in PHP and write it in javascript to generate the Google Maps Static Image in case someone needs it like I did. This code uses the response from the Directions API

var request = directionsDisplay.directions.request;
var start = request.origin.lat() + ',' + request.origin.lng();
var end = request.destination.lat() + ',' + request.destination.lng();
var path = directionsDisplay.directions.routes[0].overview_polyline;
var markers = [];           
var waypoints_labels = ["A", "B", "C", "D", "E", "F", "G", "H", "I", "J", "K"];
var waypoints_label_iter = 0;   
markers.push("markers=color:green|label:" + waypoints_labels[waypoints_label_iter] + '|' + start);

for(var i=0;i<request.waypoints.length;i++){
    //I have waypoints that are not stopovers I dont want to display them
    if(request.waypoints[i].stopover==true){
        markers.push("markers=color:blue|label:" + waypoints_labels[++waypoints_label_iter] + '|' + request.waypoints[i].location.lat() + "," +request.waypoints[i].location.lng());
    }           
}

markers.push("markers=color:red|label:" + waypoints_labels[++waypoints_label_iter] + '|' + end);

markers = markers.join('&');

alert("https://maps.googleapis.com/maps/api/staticmap?size=1000x1000&maptype=roadmap&path=enc:" + path + "&" + markers);

I've been doing this today, using the overview_polyline which is returned from the distance matrix, however in some cases the polyline isn't plotted on the static map when adding it to the map URL but the same one works on a dynamic map. with googles new pricing coming in we've had to make changes as our current yearly payment is to increase by other 1500%. the bonus of the static map is that you can pass postcode/zip and full addresses. you can also pass in variables which makes things easier.
