I have a series of circles and lines representing some information about a geographical location. Is it possible to reuse that (complex) geometry by simply attaching it to a single point?

In other words, I would like to use that set (of geometries) as a prototype geometry for other locations, is that possible?

series of circles + a polyline as an example

  • What do you exactly mean by "prototype geometry"? Can you give an example? – IvanSanchez Mar 9 '17 at 16:54
  • I mean a series of geometries (circles, lines, polygons) ensembled together in a layer group to graphically represent a feature. – Gamze Mar 13 '17 at 12:53
  • Like a glyph? You might want to use L.Markers for those. – IvanSanchez Mar 13 '17 at 13:41
  • No, it is not like glyph. I use L.circle multiple times. And then I group those circles. And I repeat this process for different points. So, I search for a solution where those group of circles could be called to assign a different geographical coordinate. – Gamze Mar 13 '17 at 14:30
  • Could you post a screenshot or diagram of how these work? I find it difficult to understand what you exactly mean. – IvanSanchez Mar 14 '17 at 8:39

If i understand you correctly, yes it is easy to re-use something complex with...functional abstraction !

This would look like :

function createMyComplexThingAt(lat, lon) {
    // a circle centered where you asked the complex thing
    var circle1 = L.circle([lat, lon], 8);
    // a circle which is on the top left
    var circle2 = L.circle([lat + 0.02, lon + 0.05], 8);
    // etc...
    // until
    var lgroup = L.layerGroup([circle1, circle2]);

    return lgroup;

var lgroup1 = createMyComplexThingAt(30, 44);
var lgroup2 = createMyComplexThingAt(21, 2);
var lgroup3 = createMyComplexThingAt(0.33, 5.44);

You can even give more parameters to your complex thing as a title text that would be used in popup or whatever you can think of.
