Measures and visualization methods of map projection distortions with the use of “python matplotlib library” as an example

Pędzich P.

Polish Cartographical Review

2016

Vol. 48, No. 3

101--114

The aim of the author of this article is to show the users of Geographical Information Systems how to present the distortions in a simple way. The intention of the author is also to popularize the knowledge in the scope of map projections and to inform the users of the maps that, despite all the advanced modern tools, an elimination of the problem, connected with the map projections and cartographical distortions occurring in them, has failed so far. The author presents a brief overview of the measures in the scope of distortions and methods of their presentation. It is also shown how the users can generate the maps, presenting a distortion by themselves. It is much easier to perform this type of visualization with the help of “matplotlib library”, basically everyone can compile such a map.

Uwagi o klasyfikacji ilościowych form prezentacji kartograficznej

Pasławski J.

Polski Przegląd Kartograficzny

2005

T. 37, nr 2

Po omówieniu wybranych właściwości form prezentacji kartograficznej, w artykule przedstawiono propozycję modyfikacji klasyfikacji L. Ratajskiego, podanej w podręczniku z 1989 roku.

Despite a number of theoretical dissertations there is still no generally accepted classification of cartographic methods of presentation. The classification proposed by L. Ratajski (1989) is used in Poland. Being developed in the early 1960s, it is almost 50 years old. The classification bases on the type of presented information. Methods are divided into quantitative (diagram map, choropleth map, isolines, dot method) and qualitative (areal method, pictoral method). This division is insufficient, because in measurement theory there also exists the ordinal level. Every quantitative method should therefore include presentation on ordinal level. I believe that a method known in Polish literature as signature method (e.g. city size in general geographical maps) should be moved to the quantitative group. All quantitative methods convey information using class division, so statistic data are transformed into classes. Diagram map is an exception - it can be used in continuous form (with size variable) as well as in its class division version. This aspect asks for more research from the point of cartoaraphic methods of presentation.
