Orthogonal floor plan projection

The topographic map of the United States Geological Survey (1:24 000) shows objects in an orthogonal plan projection, true to scale and in true position.

An orthogonal floor plan projection ( Greek orthós correct, straight, upright) describes the distortion-free and true-to-scale representation of situations . Buildings, traffic routes, land cover, etc. a. are orthogonally integrated into a spatial reference system, e.g. B. measured a card.
