Opis:
Application of polyhedrons as image surface in cartographic projections has a tradition of more than 200 years. The first maps relying on polyhedrons appeared in the 19th century. One of the first maps which based on an original polyhedral projection using a regular octahedron was constructed by the Californian architect Bernard Cahill in 1909. Other well known polyhedral projections and maps included Buckminster Fuller’s projection and map into icosahedron from 1954 and S. Waterman’s projection into truncated octahedron from 1996, which resulted in the “butterfly” map. Polyhedrons as image surface have the advantage of allowing a continuous image of continents of the Earth with low projection distortion. Such maps can be used for many purposes, such as presentation of tectonic plates or geographic discoveries. The article presents most well known polyhedral maps, describes cartographic projections applied in their preparation, as well as contemporary examples of polyhedral maps. The method of preparation of a polyhedral map and a virtual polyhedral globe is also presented.

Opis:
This research presents the results of the cartometric analysis of two Leonardo da Vinci’s works, i.e. the Mapa mundi and A map of Imola. The analysis of the Mapa mundi was conducted by employing various distortion measures and creating maps to show their distribution by distortion isograms. A map of Imola was analysed utilising MapAnalyst, taking advantage of the software’s tools, such as distortion grids, isolines of scale and local map rotation angles.

Opis:
This paper undertakes the problem of mapping a hyperboloid cooling tower on a single plane. Measurements performed by ground-based laser scanning technology quickly deliver substantial amounts of geometric data of the tower’s outer wall. The essence of the article is projection of the rotational hyperboloid on a plane. The shape of the hyperboloid cooling tower is not directly expandable to a single plane. Mapping a hyperboloid shape on a plane is, therefore, associated with distortions. This paper presents a comparison between cylindrical and conic projection of a hyperboloid cooling tower. The most popular method of mapping hyperboloid is cylindrical projection. The cylinder’s side surface is easily developed on the drawing sheet. For the hyperboloid cooling tower, the biggest distortions occur in the latitudinal direction and reach the highest values at the top and bottom edges. The equation (13) describe distortion for the cylindrical projection. The equation (18) describe distortion for the conical projection. This paper presents results obtained from the performed measurement. The analysis found that cone mapping produces less distortion than cylindrical projection for the hyperboloid cooling tower. We think, that in conical projection, the shape of a hyperboloid cooling tower and theoretical conic shape have better corresponding together than in cylindrical projection.

Opis:
Transnational communication lines differ from other objects of the economy both in form and size, and in the task of their geodetic support, which requires the development of special methods for its solution. One of the ways of geodetic support with high accuracy is the choice of optimal (with minimal distortion) geodetic projection for the territories of transnational communication lines. Composite projection is one of the most appropriate methods to choose the optimal projection. This article presents the argumentation and results of experimental calculations for the implementation of optimal geodetic projection for transnational communication lines in Azerbaijan.
