I have a leaflet map that I will with this:
$('#map').height($(window).height()-64+'px');
var map = L.map('map' , { zoomControl:false }).setView([51.505, -0.09], 13);
new L.Control.Zoom({ position: 'bottomright' }).addTo(map);
L.tileLayer('http://{s}.tile.osm.org/{z}/{x}/{y}.png', {
attribution: '© OpenStreetMap contributors'
}).addTo(map);
This gives a greyscale kinda boring map. I am trying to get a more colorful one for open street view like the one in the below link of you click on the layers and click "streets"
http://leafletjs.com/examples/layers-control-example.html
If you want to have a colored OSM map, change your L.tileLayer function with this
L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
maxZoom: 19,
attribution: '© OpenStreetMap'
});
Here is a complete list of various basemap providers for leaflet.

I have a Leaflet map with a control with openstreetmap and googlemap, when I load my page I see a openstreetmap for a istance and then swich to googlemap but I want to show openstreetmap for default.
this is my code:
<script>
var openStreetMap = L.tileLayer('https://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
attribution: '© OpenStreetMap contributors'
});
var googleMap = L.tileLayer('http://{s}.google.com/vt/lyrs=m&x={x}&y={y}&z={z}', {
maxZoom: 20,
subdomains: ['mt0', 'mt1', 'mt2', 'mt3']
});
var map = L.map('map', {
center: [43.44084,11.8602],
zoom: 13,
layers: [openStreetMap, googleMap]
});
var baseMaps = {
'openStreetMap': openStreetMap,
'googleMap': googleMap
};
L.control.layers(baseMaps).addTo(map);
map.spin(true);
$.getJSON("http://localhost/fit-file-analysis-2/geojson.php",function(data){
L.geoJson(data).addTo(map);
map.spin(false);
});
You add an object of baseMaps to your map but you didn’t affect a tile layer.
Like #IvanSanchez says, you must add the tile layer to your map:
openStreetMap.addTo(map);
I have implemented the following piece of code where I need to fit a layer over a map, that I made using QGIS. But the coordinates are not working correctly, what should I do? The problem are the wrong coordinates or there is a way to fit the layer in the map correctly using overlay?
var L;
var initialCoordinates = [-14.91, -43.20];
var initialZoomLevel = 4;
// create a map in the "map" div, set the view to a given place and zoom
map = L.map('heatmap').setView(initialCoordinates, initialZoomLevel);
L.map('map', {
crs: L.CRS.EPSG4326
});
// add an OpenStreetMap tile layer
// L.tileLayer('https://cartodb-basemaps-{s}.global.ssl.fastly.net/light_all/{z}/{x}/{y}{r}.png', {
// attribution: '© OpenStreetMap © CartoDB',
// maxZoom: 19
// }).addTo(map);
L.tileLayer('https://stamen-tiles-{s}.a.ssl.fastly.net/toner-lite/{z}/{x}/{y}{r}.{ext}', {
attribution: 'Map tiles by Stamen Design, CC BY 3.0 — Map data © OpenStreetMap',
subdomains: 'abcd',
minZoom: 0,
maxZoom: 18,
ext: 'png'
}).addTo(map);
// [[5.32, -28.95], [-33.1999, -73.9]]
var imageUrl = '/images/temperatureMapDefault.png', //temperatureMapDefault.png
imageBounds = [[5.32, -28.95], [-33.1999, -73.9]]; // [[ymin, xmin][ymax, xmax]]
L.imageOverlay(imageUrl, imageBounds).addTo(map);
The coordinates for the bounding box are working just fine; the problem is in the projections.
Your QGIS project, and your output image, are using EPSG:4326. Leaflet uses EPSG:3857 (spherical mercator) for display. If you try to overlay a stretched EPSG:4326 image over a EPSG:3957 one, the top and bottom edges will fit but you'll experience a vertical shift.
You can see this more clearly by creating a bigger image in EPSG:4326 with country boundaries. I encourage you to experiment.
Please read https://docs.qgis.org/2.18/en/docs/user_manual/working_with_projections/working_with_projections.html and related documentation in order to configure your QGIS project to use a different CRS.
Anyone having problems to display Open street Map on leaflet?
Seems like the server is been down for two days?
var markersLayer = new L.LayerGroup(); // NOTE: Layer is created here!
var osm = L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png', {
attribution: 'Map data © OpenStreetMap ',
maxZoom: 18
});
var cartodb_light = L.tileLayer('http://{s}.tile.openstreetmap.org/{z}/{x}/{y}.png',{
attribution: 'Map data © OpenStreetMap contributors, © CartoDB ',
maxZoom:18
});
My ESRI layer does display but not the OSM? Anyone knows whats going on? It seems i cannot display the standard map on the website also... ?

Following first code snippet doesn't display map
Snippet 1:
var mapEle = document.getElementById('map');
var map = L.map(mapEle);
L.tileLayer('http://{s}.mqcdn.com/tiles/1.0.0/map/{z}/{x}/{y}.png', {
attribution: '© OpenStreetMap contributors | Tiles Courtesy of MapQuest <img src="http://developer.mapquest.com/content/osm/mq_logo.png" width="16" height="16">',
subdomains: ['otile1','otile2','otile3','otile4']
}).addTo(map);
Snippet 2:
var mapEle = document.getElementById('map');
var map = L.map(mapEle).setView([43.07265,-89.400929], 10);
L.tileLayer('http://{s}.mqcdn.com/tiles/1.0.0/map/{z}/{x}/{y}.png', {
attribution: '© OpenStreetMap contributors | Tiles Courtesy of MapQuest <img src="http://developer.mapquest.com/content/osm/mq_logo.png" width="16" height="16">',
subdomains: ['otile1','otile2','otile3','otile4']
}).addTo(map);
Made change in second line of first snippet, Added setView([43.07265,-89.400929], 10), it displays map, am i missing something, or setview is compulsory?
UPDATE
leaflet version: 0.7.3
with setView(), you tell leaflet which tile(s) http://{s}.mqcdn.com/tiles/1.0.0/map/{z}/{x}/{y}.png must be fetched from the server.
So yes it is compulsory
