Selecting Map Projections in Minimizing Area Distortions in GIS Applications
Sensors, 2008 Varioussoftware for Geographical Information Systems (GISs) have been developed and used in many different engineering projects. In GIS applications, map coverage is important in terms of performing reliable and meaningful queries. Map projections can be

Approximately Conformal, Equivalent and Equidistant Map Projections [PDF]
Journal of Geodesy and Geoinformation Science, 2022 If geodetic coordinates from an ellipsoid are included in the equations of a projection for mapping a sphere instead of geographical coordinates, the result will be a projection of the ellipsoid into a plane.

The optimal conformal projection for pan-European mapping [PDF]
Geodetski Vestnik, 2020 There is an increasing need for pan-European spatial datasets, mainly to support the common European Union policies. This has inevitably raised demands for adopting pan-European cartographic projections to visualize the spatial data.

Construction of rhombic triacontahedron discrete global grid systems
International Journal of Digital Earth, 2022 Discrete Global Grid System (DGGS) is a new multi-resolution geospatial data modeling and processing scheme for the digital earth. The icosahedron is commonly regarded as an ideal polyhedron for constructing DGGSs with small distortions; however, the ...

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

From Conic to Cylindrical Map Projections
Geodetski Vestnik, 2023 In books and textbooks on map projections, cylindrical, conic and azimuthal projections are usually considered separately. It is sometimes mentioned that cylindrical and azimuthal projections can be interpreted as limiting cases of conic, but this is ...
