TheGauss–Kruger projection properties of the Gauss-Kruger projection were analyzed. It is shown that, although the linear distortions of this projection are greater than those of the best conformal projectionConformal projection for an area bounded by two nearby meridians, the difference between these values is an order of magnitude smaller than the distortions themselves. It is also demonstrated that conformity is not an indisputable advantage of the Gauss-Kruger projection. The widespread use of the Gauss-Kruger projection for cadastral purposes has revealed that the most important property of the projection is not the distortion of angles or line lengths, but rather the distortion of areas. Even though angles in conformal projections are not distorted, corrections are still applied to them during processing.
