I'm working with a map, drawing a route between two points, using Ionic Cordova.
Everything works fine except I can't hide itinerary (directions given by gps) and in small smartphones itinerary doesn't let user interacts with map.
I googled examples but I see no diference with my code.
this.geolocation.getCurrentPosition().then(resp=>{
this.localizacion = resp.coords;
this.posicion = [this.localizacion.latitude, this.localizacion.longitude];
this.map = leaflet.map('map', {
center: this.posicion,
zoom: 16
});
leaflet.tileLayer("http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png", {
attribution: '© Código 200'
}).addTo(this.map);
let control = leaflet.Routing.control({
waypoints: [
leaflet.latLng(this.localizacion.latitude, this.localizacion.longitude),
leaflet.latLng(result[0].latitude, result[0].longitude)
],
routeWhileDragging: true,
show: false
}).addTo(this.map
let markerGroup = leaflet.featureGroup();
let marker: any = leaflet.marker(this.center);
markerGroup.addLayer(marker);
let marker2: any = leaflet.marker(this.posicion);
markerGroup.addLayer(marker2);
this.map.addLayer(markerGroup);
});
Could anyone told me if I did something wrong?? or another way to hide itinerary
Well, I could fix it mixing online css feaflet use and a customized css into my project where I added the show:fakse and all what i needed.

I'm learning openstreetmaps and openlayers. I started with application approach (Parcel + openlayers). Most of examples you find here, that could possibly help me are used with older code, which as I understand does not support all features such as Clusters and other stuff. I tried them and was not able to make it work with new environment (of cause it was not just copy-past). My question is relatively simple, I want to customize Features with [Points][1], docs say I can set their style by [setStyle][2] they also have example where it actually works. I used that example to start but whatever style I describe in there I see no new point on a map, and there are none any errors in Parsel or in browser console. If I do not use setStyle I see my point on a map. I tried different ways to set a style but none of them actually worked for me.
I do it like that, first I set style:
var iconStyle = new Style({
fill: 'red'
});
After that I add point to features array like that
features.push( new Feature({
geometry: new Point(coordinates),
address: 'Адрес точки 2',
ordererName: 'Имя человека 2',
})
);
and afterwards I set a style for a point:
features[1].setStyle(iconStyle);
and put all of that into map:
var source = new VectorSource({
features: features
});
var vectorLayer = new VectorLayer({
source: source
});
var raster = new TileLayer({
source: new OSM()
});
//EPSG:3857 - web
//EPSG:4326 - GPS
var map = new Map({
layers: [
raster,
//source,
//clusters,
vectorLayer
],
target: 'map',
view: new View({
center: transform(map_center, 'EPSG:4326', 'EPSG:3857'),
zoom: 13
})
});
So my question is how to set a style for a point and actually see on a map? If you also capable to suggest how to add such a custom Point on click on a map after you created a map with layers and points that is highly appreciated. Thanks in advance.
Your style setup isn't complete, to display a point your need to style it as an image, for example a red filled circle
var iconStyle = new Style({
image: new CircleStyle({
radius: 10,
fill: new Fill({
color: 'red'
})
})
});
If adding a feature after creating the map it might look like this:
map.on('click', function(event) {
var feature = new Feature({
geometry: new Point(event.coordinate)
...
...
});
feature.setStyle(...);
source.addFeature(feature);
});
I am trying to change an OpenLayers 2 call to Leaflet, but when I do the map is displayed fine at zoom level 0, but every time I zoom in, the map doubles from the previous number. Any suggestions as to why? Here is a picture to what its doing.
OpenLayers 2 map options
var options = {
projection: new OpenLayers.Projection("EPSG:3857"),
displayProjection: new OpenLayers.Projection("EPSG:4326"),
units: "m",
maxResolution: 156543.0339,
maxExtent: new OpenLayers.Bounds(-20037508.34, -20037508.34,
20037508.34, 20037508.34),
controls: [
new OpenLayers.Control.Navigation(
{dragPanOptions: {enableKinetic: true}}
)
]
};
OpenLayers 2 code
var bathyEsri = new OpenLayers.Layer.XYZ(
' ESRI Ocean'
,'http://services.arcgisonline.com/ArcGIS/rest/services/Ocean_Basemap/MapServer/tile/${z}/${y}/${x}.jpg'
,{
sphericalMercator : true
,isBaseLayer : true
,wrapDateLine : true
,opacity : 1
,visibility : true
}
);
Leaflet Options
var options = {
worldCopyJump: true,
maxBounds: L.LatLngBounds([20037508.34,20037508.34],[-20037508.34,-20037508.34]),
crs: L.CRS.EPSG4326,
center: [39.73, -104.99],
zoom: 0
};
Leaflet Code
var bathyEsri = L.tileLayer('http://services.arcgisonline.com/ArcGIS/rest/services/Ocean_Basemap/MapServer/tile/${z}/${y}/${x}.jpg');
Your problem is basically a typo.
Your analysis is also misleading: it's not that the map is being "duplicated", but rather every tile being requested is the 0/0/0 tile. If you use the network inspection tools of your browser, you'll see that the tile URL is something like https://services.arcgisonline.com/ArcGIS/rest/services/Ocean_Basemap/MapServer/tile/$3/$4/$5.jpg , but the tile image corresponds to the /0/0/0.jpg tile.
If you look at those URLs a bit more closely, you'll notice some "extra" $ signs. Why are those there? Well, consider that you wrote your tilelayer URL scheme as
var bathyEsri = L.tileLayer('http://...../tile/${z}/${y}/${x}.jpg');
But keep in mind that the Leaflet documentation clearly states:
var bathyEsri = L.tileLayer('http://...../tile/{z}/{y}/{x}.jpg');
Change this, and everything will magically start working.
I am struggling with jsfiddle trying to create a running example which uses leaflet.
because I was not successful I searched for some examples and found the following one working:
http://jsfiddle.net/kedar2a/LnzN2/2/
I then copied the example in a new fiddle
https://jsfiddle.net/aLn3ut5z/1/
but it is still not working...
when inserting the external resources, there was the following error:
jsfiddle.net says:
You're loading resources over HTTP not HTTPS, your fiddle will not
work. Do you wish to continue?
any suggestions what is wrong here?
p.s.: below is the code of the jsfiddle windows:
HTML:
<div id="map"></div>
CSS:
#map {
height: 500px;
width: 80%;
}
JAVASCRIPT:
// We’ll add a tile layer to add to our map, in this case it’s a OSM tile layer.
// Creating a tile layer usually involves setting the URL template for the tile images
var osmUrl = 'http://{s}.tile.osm.org/{z}/{x}/{y}.png',
osmAttrib = '© OpenStreetMap contributors',
osm = L.tileLayer(osmUrl, {
maxZoom: 18,
attribution: osmAttrib
});
// initialize the map on the "map" div with a given center and zoom
var map = L.map('map').setView([19.04469, 72.9258], 12).addLayer(osm);
// Script for adding marker on map click
function onMapClick(e) {
var marker = L.marker(e.latlng, {
draggable: true,
title: "Resource location",
alt: "Resource Location",
riseOnHover: true
}).addTo(map)
.bindPopup(e.latlng.toString()).openPopup();
// Update marker on changing it's position
marker.on("dragend", function(ev) {
var chagedPos = ev.target.getLatLng();
this.bindPopup(chagedPos.toString()).openPopup();
});
}
map.on('click', onMapClick);
The Leaflet CDN doesn't support SSL yet. You can use something not requiring https, like playground-leaflet which is just a fork of JSBin with leaflet libraries easily selectable.
Alternatively, you could use Leaflet from cdnjs.net, which does support https.
I am using Mapbox GL directions plugin inside my app where I set the origin on map load and set driving destination upon user click on any location on the map. I am now trying to remove the top left search origin / destination box yet after extensive research can't figure out how to do so, can someone please help by telling me how to do so? Thanks.
Code I am using in my app below:
var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/mapbox/streets-v8',
center: [userCoordinates.coords.longitude, userCoordinates.coords.latitude],
zoom: 15
});
var directions = new mapboxgl.Directions({
unit: 'metric',
profile: 'driving'
});
map.addControl(directions);
directions.setOrigin([userCoordinates.coords.longitude, userCoordinates.coords.latitude]);
map.on('click', function(e) {
var features = map.queryRenderedFeatures(e.point, { layers: ['gsLayer'] });
if (!features.length) {
return;
}
var feature = features[0];
directions.setDestination([feature.geometry.coordinates[0], feature.geometry.coordinates[1]]);
});
I couldn’t figure this out either since there is no documentation, but finally I read through the mapbox-gl-directions.js file and I think I found out how to do it.
In your example, you should embed the controls like this in order to remove the origin / destination box:
var directions = new mapboxgl.Directions({
unit: 'metric',
profile:'driving',
container:'directions', // Specify an element thats not the map container.
// UI controls
controls: {
inputs: false,
instructions: true
}
});
map.addControl(directions);
I'll assume you are using Mapbox GL Javascript, and looking at this example it appears map.addControl(new mapboxgl.Directions()); is what is adding the controller. Within your code you gave you also have this map.addControl(directions);. Try removing it and see what happens.
Hope this helps!
I need high-res map images for my application (solar power system design). Bing Maps in OL is good for finding the right building, but too low-res for laying out solar panels. So, I want to use a small high-res static map for doing the layout. Here's what I have currently. First load the Bing Maps layer:
var layers = [];
var baseBingMapLayer = new ol.layer.Tile({
source: new ol.source.BingMaps({
key: 'XXXXX',
imagerySet: 'AerialWithLabels',
})
});
layers.push(baseBingMapLayer);
var map = new ol.Map({
layers: layers,
target: 'map',
view: new ol.View({
center: [-13569845.9277,4485666.89612],
zoom: 5,
})
});
Then when I want to load the static map, the strategy is to remove the Bing Maps layer and then add the static image layer. I'm doing the following:
var extent = [0, 0, 1024, 768];
var projection = new ol.proj.Projection({
code: 'xkcd-image',
units: 'pixels',
extent: extent
});
var staticURL =
"https://maps.googleapis.com/maps/api/staticmap"
+ "?center=37.7431569802915,-121.4451930197085&"
+ "zoom=20&size=1024x768&scale=2&zoom=3&"
+ "format=jpg&maptype=satellite"
+ "&key=XXX";
map.removeLayer(baseBingMapLayer);
var imageLayer = new ol.layer.Image({
source: new ol.source.ImageStatic({
url: staticURL,
imageSize: [1024,768],
projection: projection,
imageExtent: extent
})
});
var imageLayerView = new ol.View({
projection: projection,
center: ol.extent.getCenter(extent),
zoom: 2
});
map.addLayer(imageLayer);
map.addView(imageLayerView);
Needless to say, this isn't working. I just get a blank screen with no exceptions thrown.
I actually had some success using jQuery to just empty the entire map div and start over with a new map object. However this seems to cause other problems and didn't seem like the right approach to me.
I'm going to continue working on this problem, but thought I would post since I'm sure I won't be the last person to try this little stunt :-)
