+ * @short_description: Single point markers
+ *
+ * Each #GisMarker represents some point on the earth with some form of
+ * content. Commonly this is used to mark geographic features such as cities or
+ * states.
+ *
+ * While markers represent a place in three dimensions somewhere on, below, or
+ * above the surface of the earth, they are drawn in 2 dimensions so that they
+ * look normal and readable by the user. Due to this, GisObjects should almost
+ * always be added to the GIS_LEVEL_OVERLAY level so they are drawn "above" the
+ * actual earth.
