Adding Custom Markers to the Flight Map


I am still very new to developing custom content for QGroundControl and need some advice on where to start with the dynamic addition/placement/removal of geo-rectified map markers. We have developed a custom plugin with a custom QML layer that contains several new static controls, so we’ve made the QML <-> C++ connection, but I’m not sure where to begin with custom map markers that rely on the lat/long boundaries of the map. Any help is appreciated!
