Abstract Map projections are very important in the compilation of various types of maps and spatial databases. Geographical information systems provide their users with the significant opportunities in the choice of map projections, coordinate systems, their definitions and transitions between them. The role of map projection can be considered depending on an objective, for which a map has to be used, user of this map and a form of its publication. The Internet, mobile devices and GIS caused that the map projections are used for two main purposes: data visualization and performing of calculations and analyses. The role of map projections is still important, despite the changes occurring in cartography. The rules for the applications of map projections developed over the centuries are still valid. However, the new rules resulting from the new functions of map projections are also created. The aim of this article, that is the author’s overview of map projections, is to illustrate the broad spectrum of applications for the map projections.

This work presents datasets that can be used for getting a good understanding of an essential geoscience content knowledge that describe earth’s coordinate systems. This include coordinate system used for spherical/spheroidal earth with latitudes and longitudes and their subsequent transformations to 2d maps on a variety of media (paper as well as digital) using the process of map projections. The datasets include PDF documents that are embedded with 3d models, animations and mathematical equations. The dataset has separate PDF documents for geographic (for spherical earth) and projected (2d) coordinate systems. Additionally, the data set include individual 3d models that can be used in various digital systems (including apps) and the animations in mp4 format that can be watched on most of the modern digital devices.

The 28th International Cartographic Conference ICC 2017 was held in Washington, DC in July 2017. The conference is a significant event in the world of cartography setting the path of development for the next 2 years. 40 topics were offered to participants of the conference in accordance with which they had to make oral presentations or posters and to submit articles. It should be noted the trend of ICC 2017 to expand the topics. For example, geospatial technologies were added to the section “Education and training”; coordinate systems, transformations and conversions were added to the section “Map projections”; extrasolar and celestial cartography were added to the section “Planetary cartography”. Cartographic and technical exhibitions, Barbara Petchenik International children’s map competition and exhibition, competitions in orienteering were held on the conference. Meeting of commissions and working groups of the International Cartographic Association, business meetings before and after the conference were organized. Also technical tours to relevant companies and organizations were proposed to participants. The article highlights the key events and ideas expressed during the conference.

A redefinition of the North American geodetic networks may well require a reappraisal of the various plane coordinate systems in use in North America. Now “plane coordinate system” and “map projection” are really only different names for the same thing. An approach to coordinate conversion is described in which each map projection (plane coordinate system) is not analyzed as an individual, but the whole set of map projections is regarded as an integrated system. The various projections are displayed in a “family tree” and conversion between two coordinate systems is performed by following the most direct path in this tree. The advantages of this approach are that 1) reduction to latitude and longitude as an intermediate step is usually unnecessary and 2) the individual steps in the tree are usually quite simple mathematically owing to the flexibility in the parameters used. The traditional approach using latitude and longitude as essential parameters often leads to ugly mathematical functions best approximated by Taylor series whose coefficients may be quite awkward to determine.
