Abstract

The work deals with setting up the equations of normal aspect of gnomonic perspective conical projections. The extreme values of local linear deformations and main directions are being then researched for these projections. The absence of local deformation in all directions is being closely examined and determination of the directions along which there are no azimuth or linear deformations is being considered in details. The equations of constant distortions curves of angles and areas are being derived. All theoretical researches are illustrated by means of adequate graphic presentations.
