I am not good a JS at all but after following the examples from the MAPBOX website I am unable to render a map at all. Code is exactly as it should be according to the website. The only error that shows up Can't find variable: mapboxgl. After researching this I have not found anything on this. What am I doing wrong?
MyCode:
<script>
mapboxgl.accessToken = '<? print $mapboxapi; ?>';
var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/streets-v11', // stylesheet location
center: [<? print $SQL["long"] ?>, <? print $SQL["lat"] ?>], // starting position [lng, lat]
zoom: 9 // starting zoom
});
var marker = new mapboxgl.Marker()
.setLngLat([<? print $SQL["long"] ?>, <? print $SQL["lat"] ?>])
.addTo(map);
</script>
This renders out this code:
<script>
mapboxgl.accessToken = 'xxxxxxxxxxxxxxxxxxxxxxxx';
var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/streets-v11', // stylesheet location
center: [-00.00000, 00.000000000], // starting position [lng, lat]
zoom: 9 // starting zoom
});
var marker = new mapboxgl.Marker()
.setLngLat([-00.00000, 00.000000000])
.addTo(map);
</script>
You probably haven't included the necessary script and CSS files in your <head> section. These bits:
<script src="https://api.mapbox.com/mapbox-gl-js/v1.12.0/mapbox-gl.js"></script>
<link href="https://api.mapbox.com/mapbox-gl-js/v1.12.0/mapbox-gl.css" rel="stylesheet" />

I am trying to add arcgis 3d layer in mapbox with DeckGL. But I have this error (Uncaught TypeError: Tile3DLayer is not a constructor)
If I could bring data from arcgis sceneserver ,I try add two maps like compare(mapbox gl swipe tool) them.
maybe there are different ways to solve this problem. Taking the arcgis data I need and calling two maps on the same web page. Then make a presentation with the comparison tool between these maps.

i'm looking for import GPX file inside my Leaflet map
but when i try the site it respond with L.GPX is not a constructor
i only have that in my head
<script src="https://unpkg.com/leaflet#1.7.1/dist/leaflet.js"></script>
and that inside body
<div id="map"></div>
<script>
var sites = {!! json_encode($markers) !!};
var map = L.map('map').setView([{{ config('leaflet.map_center_latitude') }}, {{ config('leaflet.map_center_longitude') }}], {{ config('leaflet.zoom_level') }});
L.tileLayer('https://api.maptiler.com/maps/streets/{z}/{x}/{y}#2x.png?key=2Qw6dd02HLfOXS3LDGMP', {
attribution: '© MapTiler © OpenStreetMap contributors'
}).addTo(map);
var marker;
sites.forEach(element => {
marker = L.marker([element[0], element[1]]).addTo(map);
});
var gpx = '/resources/gpx/pont.gpx'; // URL to your GPX file or the GPX itself
new L.GPX(gpx, {
async: true,
polyline_options: {
color: '#ff0000',
}
}
).on('loaded', function(e) {
map.fitBounds(e.target.getBounds());
}).addTo(map);
</script>
You have to load the plugin before you can use it:
Usage
First, include the Leaflet.js and Leaflet-GPX scripts in your HTML
page:
As described, add the following line, in your header or before your script
<script src="https://cdnjs.cloudflare.com/ajax/libs/leaflet-gpx/1.4.0/gpx.min.js"></script>
Leaflet zooms so now and than too much on clicking a cluster.
A small part of 1 marker is shown on the right and a small part from the other marker is shown on the left side of the map.
My workaround is counting markers in scope and re-adjust the zoomlevel when the counter = 0.
Shouldn't that be in the zoomcalculation of leaflet?
The zoom correction:
mcg.on('clusterclick', function () {
if (markersInScope == 0) {
var zoom = map.getZoom();
map.setZoom(zoom - 1);
}
});
You could try adjusting the zoom to fit the bounds of the mcg and add some padding
mcg.on('clusterclick', function () {
map.fitBounds(mcg.getBounds().pad(0.5));
}
});
If you add the markers to a featureGroup, the bounds for the group will available to you:

I'm working on MapBoxgl and I want to add several markers.
Here is my index.html:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8" />
<link href=" /assets/css/bootstrap.min.css " rel="stylesheet" />
<link href=" /assets/css/mapbox-gl.css " rel="stylesheet" />

<body>
<div id="map"></div>
<script src="/assets/js/mapbox-gl.js"></script>
<script src="/assets/js/map-style.js"></script>
</body>
</html>
This is map-style.js:
var map = new mapboxgl.Map({
container: 'map',
center: [57.3221, 33.5928],
zoom: 5,
style: style
});
var geojson = {
type: 'FeatureCollection',
features: [{
type: 'Feature',
geometry: {
type: 'Point',
coordinates: [30.61, 46.28]
},
properties: {
title: 'point 1',
description: 'point 1 Description',
message: 'point1',
iconSize: [25, 25]
}
},
{
type: 'Feature',
geometry: {
type: 'Point',
coordinates: [30.62, 46.2845]
},
properties: {
title: 'point 2',
description: 'point 2 Description',
message: 'point 2',
iconSize: [25, 25]
}
}]
};
map.on('load', function () {
// add markers to map
geojson.features.forEach(function(marker) {
// create a DOM element for the marker
var el = document.createElement('div');
el.className = 'markers';
el.style.backgroundImage = 'url(assets/marker-azure.png)';
//el.style.width = marker.properties.iconSize[0] + 'px';
el.style.height = marker.properties.iconSize[1] + 'px';
el.addEventListener('click', function() {
window.alert(marker.properties.message);
});
// add marker to map
new mapboxgl.Marker(el)
.setLngLat(marker.geometry.coordinates)
.addTo(map);
});
});
And following is main.css portion related to map and marker:
#map { position:absolute; top:0; bottom:0; width:100% }
.markers {
display: absolute;
border: none;
border-radius: 50%;
cursor: pointer;
padding: 0;
}
So, my problem is that when I add width property to markers, their icon be displayed correctly (with a bit stretch) but they are in wrong coordinate and move on zoom, like picture below:
On the other hand, if width property is eliminated, they are in right place and does not move on zooming, but they are very stretched and in fact as wide as screen (following image):
It's noteworthy that I've used bootstrap. Can it be the reason of this? If not, what's the problem?
Thanks
import 'mapbox-gl/dist/mapbox-gl.css';
Adding import css works for me.
I found the solution and share it here with others who will encounter this problem. The problem caused because of using a not-most-recent version of the library. After upgrading to the latest release, I could get rid of that problem.
Note that these kinds of problems sometimes occur, when you use npm. Make sure that the library is downloaded completely and It's the latest release.
Latest releases of MapBox can be found at here.
had similar issue, the marker seemed to change position on zoom in/out, fixed it by setting offset, thought to share if it can help others, here is the fiddle
// add marker to map
var m = new mapboxgl.Marker(el, {offset: [0, -50/2]});
m.setLngLat(coordinates);
m.addTo(map);
(Using mapbox 1.13.0)
I had a similar issue where the popups weren't displaying and would change position based on zoom.
Mapbox officially states that you need to include the css file to have markers and popups work as expected.
https://docs.mapbox.com/mapbox-gl-js/guides/install/
HOWEVER, you can also copy that css directly into a component and use that as an element. For example:
export default function MarkerMapTest(props) {
const mapContainer = React.useRef(null)
const map = React.useRef(null)
const elemRef = React.useRef(null)
React.useEffect(() => {
map.current = new mapboxgl.Map({
container: mapContainer.current,
style: "mapbox://styles/mapbox/dark-v10",
center: [151.242, -33.9132],
zoom: 14,
})
const marker = new mapboxgl.Marker({
element: elemRef.current,
})
.setLngLat([151.242, -33.9132])
.addTo(map.current)
}, [])
return (
<div
style={{ width: 600, height: 600, backgroundColor: "gray" }}
ref={mapContainer}
>
<div
style={{
width: 30,
height: 30,
borderRadius: 15,
backgroundColor: "red",
position: "absolute", // !
top: 0, // !
left: 0, // !
}}
ref={elemRef}
/>
</div>
In my case the svg I used had some space around the real content. That way it seemed for me that the marker was moving. A simple fix was to remove the space around the content (e.g. with the "Resize page to drawing or selection" option of inkscape: https://graphicdesign.stackexchange.com/a/21638)
Also it is important to set display: block on the svg-marker. See: https://stackoverflow.com/a/39716426/11603006

Is there any direction service provided by openlayer3 please point to sample to accomplish it
If you have coordinates along the lanes you can use MultiLineString instead of LineString.
You need to use a routing service for such action. You may setup your own service or you may use any online available. here you can find a list of free online routers and decide which one best feet to your needs.
Once you get your root polyline out of the selected service you can then decode (if encoded) and draw your line within your ol3 map.
Also cosider, depending on the service you are going to use, that ol3 offers a class for reading and writing data in the Encoded Polyline Algorithm Format which is described here
