[GIS] Make two layers editable in leaflet draw

leaflet

I use Leaflet draw to draw markers and polygons on a map. The created features are saved to two separate feature groups. One feature group for the markers and one for the polygons. Now I want to edit the features. How can I add two feature groups as editable layers:

'edit': {
  'featureGroup': featureGroupMarker, featureGroupPolygon
}

I ended up solving it by adding twice the Leaflet drawControl to the map. One time for markers and one time for the polygons. This way I can specify which layer should be edited.

[GIS] select two markers & draw line between them in leaflet

So it seems to me all you have to do is take the two markers you have selected and grab their latlngs and add them to the polyline.

var latlngs = Array();

//Get latlng from first marker
latlngs.push(marker1.getLatLng());

//Get latlng from first marker
latlngs.push(marker2.getLatLng());

//You can just keep adding markers

//From documentation http://leafletjs.com/reference.html#polyline
// create a red polyline from an arrays of LatLng points
var polyline = L.polyline(latlngs, {color: 'red'}).addTo(map);

// zoom the map to the polyline
map.fitBounds(polyline.getBounds());

Edit

In case you are looking for a way to also get the selected markers. You will need to probably listen to the click event of each marker and add the markers to an array that contains your selected markers. You will just need to limit that array to two entries. This is not an optimal solution but should get you there and will allow you to easily extend if you want more than two markers.

[GIS] how to bound markers with base layers : leaflet

Here is what you can do:

Wrap all your base layers in L.LayerGroup and add these layer groups to L.Control.Layers.
Store reference to current base layer by subscribing to baselayerchange event of a map.
When you add new marker, add it to group of current base layer instead of directly on map
