Is it possible in Leaflet, to share a single common boundary within two polygons, other than two overlapped boundaries within a MultiPolygon layer?
In this plugin (leaflet-geoman), they have mentioned there is an option in pro version, called pining. But in that pining option (you can see it on the gif), it has duplicate boundaries on top of each other. What I want to achieve is, multipolygons must share common boundaries like on this question. But on this quetion it was about MultiLineStrings, not about MultiPolygons. The answer was given using TopoJSON. It has a method called
Returns the GeoJSON MultiLineString geometry object representing the mesh for the specified object in the given topology. This is useful for rendering strokes in complicated objects efficiently, as edges that are shared by multiple features are only stroked once.
But there is no method for returning MultiPolygons for a given topology. It only has a method for returning MultiPolygons called
to merge multiple polygons into a single polygon whilst removing interior borders.
So my ultimate goal is to have MultiPolygon layer which consist with single shared boundary within two polygons, not duplicated boundaries on top of each other or overlapped boundaries. What I need is exactly in this video. But it is done using overlapped boundaries. Not using shared single boundaries.
In its current design, editing large datasets is not possible because of the massive amount of time required to find matching and missing vertices.
Is there anyway I can achieve this using Leaflet or any other method.
