Ichnography (Gr. τὸ ἴχνος, íchnos, "track, trace" and γράφειν, gráphein, "to write"),[1] pronounced ik-nog-rəfi, in architecture, is a term defined by Vitruvius (i.2) as the ground plan of the work, i.e. the geometrical projection or horizontal section representing the plan of any building, taken at such a level as to show the outer walls, with the doorways, windows, fireplaces, etc., and the correct thickness of the walls; the position of piers, columns or pilasters, courtyards and other features which constitute the design,[2] as to scale.

Ground plans can help in creating sufficient floor space, especially for larger designs where appropriate planning is needed such as with Depot and shops, however modern architectural large-scale designs are usually done by means of computer with certain dedicated software. Ichnography today can crudely be used for small-scale plans such as Garden and Bedroom layouts,sometimes with 3D sketches. They may be used by children and other 'non-professionals' as a way to help express their imagination of design or as a form of geometrical play.
