Map Layers rendering

OsmAnd Map is rendered by layers from bottom to top. Some layers cover full map screen, some are rendered with transperancy but the order of layers is consistent, so it's important to keep track of what and in which order is rendered.

Order of layers​

Android. Most layers in Android are instance of in the method createLayers of MapLayers class. Order of each layer is depend from zOrder property during instance and set in the method getBaseOrderof OsmAndMapLayer class. Other layers are instance in the plugins.

iOS. Most layers in iOS are instance of in the method createLayers of OAMapLayers.
Order of each layer is set direcly by baseOrder property in createLayers. Other layers are instance in the plugins.

Order of icons and text​

Order of vector map icons (iconOrder) and text (textorder) are mainly set in the style, for example Default OsmAnd style.
Order of layers icons and text depends from order of layer and can be not so different than layer order. Additionally we increase order of road shields for show their above.
