I am trying to add redundancy to map POI since quite a long time for a leaflet map i use on this page : http://worldisbeautiful.net/carte/
I'm sorry if my english isn't clear, that's probably why i'm having hard time to find a solution. See when you zoom out on this map, you have multiple world maps side by side but the POI are only on one map. Is there a way to have POI on each world maps, same positions ?
I understand there is an option nowrap to avoid multiple world maps but i like the idea of moving from left/right and having the earth rotating not just a plain map.
Thanks for the help !
This is a current leaflet limitation. See this support request
I think a workaround might be to replicate the markers with +360 degrees to wrap around the world.

I need to use Longitude and Latitude coordinates on a map that will be loaded in by an external program, and I need to be able to draw things on this map and be able to zoom in and out. Thing is, I cannot draw this map, and I need to be able to interact with both the map elements and with what I'm drawing.
I tried using Google, and found that I was able to control either my canvas or the map, but not both at the same time. Plus, I could not draw things properly on top of Google's map (I'm using Easel.js).
If anyone has any sources or advice, it will be much appreciated.
OK I figured this out with help from my web dev friend. He suggested I use Google Maps, and even though I have that whole "layering" issue (with all my events being captured in the canvas and not trickling down to the 'map-canvas' div), I should go and set up events that capture things like zoom and drag, and pipe them along to my Google Map, and the result is prefect for what I am looking for.
So now I have my Easel.js canvas on top of my Google map, and I just have to set up lat/lng positions for my objects when I want them to be part of the map!
Thanks for the help, everyone!
I was drawing polygons using Polygon Creator Class on Google Maps. As you see this tool is not easy to use. For example, it's impossible to add new polygon or edit some of them after getting result code.
In following link when you zoom in between polygons you will see gaps that I want to remove. To recreate the issue please open following link and zoom in between polygons:

Now question is, how to remove gap between these polygons ? In this case I can't use the tool that I used to create this map.
And which tool is better to use in this situation ?
Thank for your time
I would suggest you using the Google's official tool for drawing, editing, locatiing and even finding driving directions for the markers you have placed on the maps. You can always save these edited maps and retrieve them later when you need them.
Please click the following link and get started!!
Even I tried drawing some polygons side by side and there were no gaps :)
Hope this would help!!
In my Meteor/Cordova/famo.us App I need a map that can be rotated with two fingers, zoomed in and out and (ideally) the names (street, city etc.) should stay horizontally aligned.
The reason is that I haven't found a (free) map like leaflet.js, Google Maps etc. that can rotate in JS. Google Maps SDK for Android and iOS respectively can do this, but the corresponding plugin (plugin.google.maps) led to trouble with famo.us.
The rotation could be done with a famo.us Surface, and I've been told that in leaflet one could pull separately the map tiles and the names (vector/jpeg?).
I apprechiate your help.
Map rotation isn't possible in Leaflet. Read this answer: https://stackoverflow.com/a/22938733/2019281. However, it is possible in openlayers but it would also rotate the labels since they are embedded in the maptiles. See this example: http://openlayers.org/en/master/examples/rotation.html. You could use a tilelayer without labels and add create your own separate layer with vectorlabels and counterrotate those. This would be a very complex solution and i guess will put an enormous strain on your performance since you're talking about a mobile solution. I would rethink the concept.
I'm using CFGMap solution to place markers on a google map (API V3) but I want the map to always be centered on a certain long/latitude. Right now it seems to center on the last marker placed on the map so if the majority are where I want the long/lat centered then one random marker will take view miles away.
Any help on this is appreciated.
Thanks!
CFGMap is infuriating for it's lack of documentation. I don't use it myself; I only tried to track down something that might help you. On the face of it, it appears only to take a tiny subset of the full API functionality and doesn't offer much else.
From what I can glean from the testmap.js found here, it appears that you can only center the map on an existing marker in your locations array (see line 616 of the github file).
_cfGMapObj.resetCenterToLoc(index);
So, for example, in the source of the example is the line:
_cfGMapObj.resetCenterToLoc($('#locID','#printLink').val());
which grabs the number from the value of the current option in the select at the top of the page.
Now, if you chose instead to knock CFGMap on the head you could employ the Map API fully and set the center of the map using the setCenter method of the API.:
map.setCenter(new google.maps.LatLng(lat, lng));
e.g.
map.setCenter(new google.maps.LatLng(57.4419, -121.1419));
which in my mind is much easier. Plus, if you decided to do this, there are tons more articles on the API on StackOverflow than there are on CFGMap. YMMV.
Using the google maps v3 javascript API, it's possible to add 'GroundOverlays' as a picture. Have a look here:
http://jsfiddle.net/9YYJB/1/
However, I'm working on a project where I'm trying to add a texture to the whole world map. Obviously I can add a single, absolutely massive gif/png overlay but I'd rather add a tiling texture. I've been digging around in the API and can't find any way to do this.
Anyone have any ideas on how this could be done?
Thanks very much
Yes, what you want to use is an image map type. This allows you to add tiles on top of the regular Google Base Map. If you want to completely replace the Google tiles, you would need to implement a Custom Map Type. My favorite example of that is the Liberty City Map.
