Electronic Navigational Charts: International Standards and Map Projections
Journal of Marine Science and Engineering, 2020 Electronic navigational charts (ENCs) are geospatial databases, compiled for the operational use of Electronic Chart Display and Information systems (ECDIS) according to strict technical specifications of the International Hydrographic Organization (IHO).

Fast flow-based algorithm for creating density-equalizing map projections. [PDF]
Proc Natl Acad Sci U S A, 2018 Significance Geographic maps are a popular means to visualize spatial statistics. Conventionally, each map region is displayed with an area proportional to the actual land area.

Map Projections Classification
Geographies, 2022 Many books, textbooks and papers have been published in which the classification of map projections is based on auxiliary (developable) surfaces and projections are divided into conic, cylindrical and azimuthal projections.

On the Definition of Standard Parallels in Map Projections
ISPRS International Journal of Geo-Information, 2023 The article belongs to the field of theoretical research on map projections. It is observed that there is no unique and generally accepted definition of standard parallels in the cartographic literature.

The Influence of Map Projections on People’s Global-Scale Cognitive Map: A Worldwide Study
ISPRS International Journal of Geo-Information, 2020 Map projections are required to represent the globe on a flat surface, which always results in distorted representations of the globe. Accordingly, the world maps we observe in daily life contexts, such as on news sites, in news bulletins, on social ...

Equidistant map projections of a triaxial ellipsoid with the use of reduced coordinates
Geodesy and Cartography, 2017 The paper presents a new method of constructing equidistant map projections of a triaxial ellipsoid as a function of reduced coordinates. Equations for x and y coordinates are expressed with the use of the normal elliptic integral of the second kind and ...

New measures for analysis and comparison of shape distortion in world map projections
Cartography and Geographic Information Science, 2019 World maps can have quite different depictions of reality depending on the projection adopted, and this can influence our perception of the world. In this respect, shape is a significant property that needs to be considered, especially when representing ...

Approximations, Errors, and Misconceptions in the Use of Map Projections
Mathematical Problems in Engineering, 2021 Global geodetic techniques currently can provide the user with worldwide millimeter accuracy. Preservation of this degree of accuracy in derived products is far from straightforward and may leave vast room for trouble in the different steps involved in ...
