A method and apparatus are disclosed for generating a display image including a map view and linepiece information for example legible text and/or characters (e.g. alphanumeric) such as road names superposed on the map view. In at least one embodiment, the technique selects linepieces that are easy to read, by (i) selecting from a first subset of alphanumeric linepieces associated with information on the map, a second sub-set of the alphanumeric linepieces satisfying predetermined criteria including display angle; and (ii) including in the display image the second sub-set of alphanumeric linepieces. The first sub-set may be selected according to distance criteria.
