Metadata: A pedagogical tool for the teaching of map projections in Elementary School

open access: yesEuropean Journal of Geography, 2021
Digital interactive maps include a set of metadata, which show the purpose the user can use the map. Metadata in digital interactive world maps inform users about important information, such as the map projection.

State Map Projection in Croatia [PDF]

open access: yesMicro, Macro & Mezzo Geoinformation
One of the basic issues of official cartography is the choice of a national projection, or rather the choice of a national coordinate system. Such a choice was relevant at the beginning of the 20th Century, then with the creation of the Independent State

Companions of the Mercator projection

open access: yesGeoadria, 2019
The late Professor Emeritus Waldo Tobler recently published a short paper, A Companion for Mercator (TOBLER, 2017). He was inspired by the often inappropriate use of the Mercator projection and suggested an alternative equal-area projection.

Proposed single-zone map projection system for Turkey

open access: yesReports on Geodesy and Geoinformatics, 2022
The coordinate base of the maps or sheets produced is the Universal Transversal Mercator (UTM) conformal projection, and it is not possible to work in a single coordinate system in Turkey.

Image-Based Angular Distortion Metric of Map Projections by Using Surface Fitting for Noise Reduction

open access: yesISPRS International Journal of Geo-Information, 2021
Measuring, analyzing, reducing, and optimizing distortions in map projections is important in cartography. In this study, we introduced a novel image-based angular distortion metric based on the previous spherical great circle arcs-based metric.

The method of construction of cylindrical and azimuthal equal-area map projections of a tri-axial ellipsoid [PDF]

open access: yesGeodesy and Cartography, 2018
The paper presents a method of construction of cylindrical and azimuthal equalarea map projections of a triaxial ellipsoid. Equations of a triaxial ellipsoid are a function of reduced coordinates and functions of projections are expressed with use of the
