How does one prevent replication of the world map - bing-maps

I am using bing ajax map to display a map of the world. However, the world map is relicated several times in the map window. How do I ensure that the atlas is not replicated.
// Instantiate map, and show world view:
var mapOptions = {credentials: "your cred here",
zoom: 2,
disableBirdseye: false,
enableClickableLogo: false,
fixedMapPosition: true,
showCopyright: false,
showScalebar: true,
showDashboard: true,
mapTypeId: Microsoft.Maps.MapTypeId.road,
center: new Microsoft.Maps.Location(45, 90)
};
map = new Microsoft.Maps.Map(document.getElementById('map'), mapOptions);
Here is the html div that contains the map.

There is no way to disable the world wrap in the Bing Maps v7 AJAX control.

Leaflet JS getBound to TileLayer

I have a web site to displaying historic maps. The maps have been tiled and are loaded as a tilelayer. Is there a way to getBound so I can set the map with fitBound. By default tilelayer does not have a getBounds method. I have tried making a featureGroup of the layer but that just raises an error. Am I missing something? Thanks.
// Initiate map
var map = new L.Map('map', {minZoom: 8, maxZoom: 18, zoom: 10});
// Display and set boundary
var layer = new L.TileLayer('../../maps/1866/{z}/{x}/{y}.png',{maxNativeZoom: 17});
//create featuregroup
var fgroup = new L.featureGroup([layer]);
fgroup.addTo(map);
map.fitBounds(fgroup.getBounds());

Error with Mapbox GL integration when adding markers: "Cannot read property 'coordinates' of undefined"

I've been working on creating a dynamically updated Mapbox GL integration inside Webflow's CMS. I've succeeded in creating an array of features that can be read by Mapbox's API, but these features won't show on the map because the coordinates are not being read by the function that creates the map markers.
I receive the following error Cannot read property 'coordinates' of undefined at map-test-page:139 which is where a longitude and latitude is assigned to the current marker via this line: .setLngLat(marker.geometry.coordinates)
Partial solution was found here, but the code I've integrated into my site doesn't have featuresIn or featuresAt functions which seem to be the only way to include a includeGeometry: true parameter.
I'm curious if I need to rethink how I've created markers and do something with a function like map.on('click', ...) reference here.
Here is a minimal version that reproduces my issue.
If you're familiar with the Webflow interface you can view a read-only version of the site.
Any help would be greatly appreciated!
Here is the Mapbox script I'm using on the page:
var map = new mapboxgl.Map({
container: 'map',
style: 'mapbox://styles/strawpari/ckp2nu3dw6cwu17nt4kqwf1vv',
center: [-13.723969, 48.360542],
zoom: 2,
pitch: 0,
bearing: 0,
antialias: true,
interactive: true
});
var geojson = {
type: 'FeatureCollection',
features: farmerArray,
};
// add markers to map
geojson.features.forEach(function(marker) {
// create a HTML element for each feature
var el = document.createElement('div');
el.className = 'marker';
// make a marker for each feature and add to the map
new mapboxgl.Marker(el)
.setLngLat(marker.geometry.coordinates)
.setPopup(new mapboxgl.Popup({ offset: 25 }) // add popups
.setHTML('<img src=\'' + marker.properties.image + '\' width=\'50\' height=\'50\' border-radius=\'50%\'>' + '<h3>' + marker.properties.title + '</h3><p>' + marker.properties.description + '</p>'))
.addTo(map);
});
And here is the code embedded in each CMS item that adds a farmer's information to the farmerArray which is being read by Mapbox. Text in double-quotations "" is a placeholder for the dynamic information populated by the CMS.
var farmerArrayItem =
JSON.stringify({
type: 'Feature',
geometry: {
type: 'Point',
coordinates: ["longitude", "latitude"]
},
properties: {
title: "name",
description: "text",
image: "imagepath"
}
});
farmerArray.push(farmerArrayItem);
It doesn't appear that you have tried using the Developer Tools to debug your code. That's definitely a skill you should pick up.
With the dev tools, you will quickly see that the value of marker at the critical point is a string:
So you just need to use JSON.parse:
geojson.features.forEach(function(markerString) {
const marker = JSON.parse(markerString);
// create a HTML element for each feature
var el = document.createElement('div');
el.className = 'marker';
// make a marker for each feature and add to the map
new mapboxgl.Marker(el)
.setLngLat(marker.geometry.coordinates)

How to define starting grid position on Leaflet's TileLayer?

My app needs to show a map within a box defined by
const corner1 = L.latLng(5.21244812011719, -96.5979537963867);
const corner2 = L.latLng(34.086555480957, -55.4220504760742);
const map = L.map(el,
{
crs: L.CRS.EPSG4326,
center: [19.6875, -76.201171875],
zoom: 3.5,
maxBounds: new L.latLngBounds(corner1, corner2),
});
L.tileLayer.wms("http://localhost:8080/wms?", {
layers: 'xxx',
tileSize: 700,
transparent: true,
maxBounds: new L.latLngBounds(corner1, corner2),
bounds: new L.latLngBounds(corner1, corner2)
}).addTo(map)
The thing is that the layer is requesting the tiles starting outside the borders defined (for example, this request was made http://localhost:8080/wms?&service=WMS&request=GetMap&layers=Mano%3AT22&styles=&format=image%2Fjpeg&transparent=true&version=1.1.1&maxBounds=%5Bobject%20Object%5D&time=2018-05-02T00%3A00%3A00.000Z&width=700&height=700&srs=EPSG%3A4326&bbox=-87.71484375,28.4765625,-56.953125,59.23828125 the bbox was -87.71484375, 28.4765625, -56.953125, 59.23828125, this contains the corners defined by me but is not optimal as it is requesting a map area that is not going to be seen on my app)
I need that leaflet request tiles that do not exceed the corners defined. How can I archieve that? Thanks in advance

reproject map extent in openlayers 3

I want to set an extend on my Openlayers 3.9.0 map.
When the page loads, I want the map to already be centered in that extend, no matter the layers. So I guess I will set an extend to the view, right?
Map contains a single OSM layer like
var layer = new ol.layer.Tile({
source: new ol.source.OSM(
{
attributions: [
new ol.Attribution({
html: 'All maps © ' +
'OpenCycleMap'
})
]
}
),
opacity: 0.8,
brightness: 0.8
});
Then I set the view
var center = ol.proj.transform([21.54967, 38.70250], 'EPSG:4326', 'EPSG:3857');
var view = new ol.View({
center: center,
zoom: 6,
extent: [2297128.5,4618333.0 , 2459120.25,4763120.0]
});
And then the map
var map = new ol.Map({
target: 'map',
layers: [layer],
view: view,
});
I used my extend in an older project, with EPSG 900913. So to convert the extend from 900913 to default Openlayers 3 3857 I went here here and I put
2297128.5, 4618333 that convereted to 2297128.5,4618333.0
and then
2459120.25, 4763120that convereted to 2459120.25,4763120.0
my two problems
1- the converted coords look similar. Did I do something wrong?
2- the map is centered ok, but not zoomed in the extend. The coords define a county in Greece and the map does not zoom there, I see the whole Greece, along with Turkey and Italy.
What I did wrong? Thanks
Thanks everyone. What I did was
Keep the OSM layer as is.
Define the limits of the county. Turns out it was EPSG 900913
var countyLimits= ol.proj.transformExtent([2297128.5, 4618333, 2459120.25, 4763120], 'EPSG:900913', 'EPSG:3857');
View is now
var view = new ol.View({
center: center,
zoom: 6,
extent : countyLimits,
maxZoom:20
});
map is
var map = new ol.Map({
target: 'map',
layers:[layer],
view: view
});
After the map is defined, fit its view in the limits
map.getView().fit(countyLimits, map.getSize());
//get the view of the map and fit it to the limits, according to the map's size
fitExtend is now deprecated, so I used fit. It is experimental , but I guess it will become standard since it replaced fitExtend.
Thanks anyway people

Several issues:
The extent [2297128.5,4618333.0, 2459120.25,4763120.0] seems to be in EPSG 3857 already and there is no need to transform it.
The extent option of ol.View is experimental and does not seem to work well. You can do the following to set the bounding box (after you declare map):
var extent = [2297128.5, 4618333.0, 2459120.25, 4763120.0];
view.fitExtent(extent, map.getSize());
The initial zoom in your example was due to the zoom level set on the view (zoom: 6). Using fitExtent() should override the initial zoom level. You can remove the zoom, center and extent options from your view declaration.
By the way, regarding the http://cs2cs.mygeodata.eu/ site, it seems that you have to specify EPSG:4326 instead of EPSG:900913 for the input coordinate, for the transformation to work correctly.
Note: ol.View.fitExtent() was renamed to ol.View.fit() in OpenLayers v3.7.0
It can be as easy as:
var min = [2297128.5, 4618333.0];
var max = [2459120.25, 4763120.0];
var extent = ol.extent.boundingExtent([min, max]);
var map = new ol.Map({
target: 'map',
layers: [
new ol.layer.Tile({
source: new ol.source.MapQuest({layer: 'osm'})
})
],
view: new ol.View({
center: ol.proj.fromLonLat([21.54967, 38.70250]),
zoom: 3,
extent: extent
})
});

OpenLayers 3 - change base map from ol.layer.Tile (Bing) to ol.layer.Image (static image)

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 :-)
