GeoMapCanvasVisualizer¶

//
// Draws a 2D world map on the OMNeT++ canvas: a background map image stretched to
// the map area and optionally overlaid with a latitude/longitude graticule, plus an
// optional absolute UTC wall-clock in the lower-left corner. It also sets up the
// shared canvas projection so that other canvas visualizers drawing scene
// coordinates (node markers, movement trails, `GeoHorizonCanvasVisualizer` footprints,
// ...) line up with this map.
//
// The map image and the graticule are drawn together as one group at this
// visualizer's `zIndex`, with the graticule on top of the image. No per-node markers
// are drawn here; node visualization is left to the other visualizers.
//
// @see ~IGeoMapVisualizer, ~GeoHorizonCanvasVisualizer, ~MobilityCanvasVisualizer
