摘要：
This article is dedicated to coordinate system binding problem. Such tasks appear during collection of geometrical information from different type of source data input system, The purpose of that binding is providing correct transformation of geometrical objects coordinates during digitalisation. This approach is used in geoinformation systems (GIS) for first step information handle. It is a digitalisation of source material. Article considers two approaches of this one: affine mapping and perspective mapping.
