A projection type can be suitable for a purpose but not for others.įlat-Earthers claim the so-called ‘flat-Earth map’ is distortion-free and use it as proof of its correctness. Some of the resulting distortions are acceptable, and others are not. Many different map projections are created to preserve different properties of the sphere-like body at the expense of other properties. It is why there are many different map projections for different purposes. Some distortions can be tolerated, and some are not. In reality, distortions are the result of transforming a curved surface into a planar form & cannot be avoided. But we generally work with two-dimensional media (paper, computer displays, televisions, phone screens, whiteboards, etc.), and it is necessary to transform the curved Earth’s surface into a planar form using a map projection.Īll maps have distortions, and flat-Earthers use it to discredit science. PARAMETER["Longitude of natural origin",0,ĭue to some difference in versions, I never quite understood whether from PROJ or GDAL, in QGIS 3.4.13 the Coordinate Reference System (CRS) is found as EPSG:102016, but in QGIS 3.10.0 it is found as ESRI:102016.Earth is a sphere. ![]() PARAMETER["Latitude of natural origin",90, It is registered in ESRI Authority with the ID 102016, and its Well Known Text (WKT) is the following: PROJCRS],ĬONVERSION["North_Pole_Azimuthal_Equidistant", The PROJ string for the ellipsoidal (datum WGS84) North Pole Azimuthal Equidistant projection is the following: ![]() The PROJ projection to transform coordinates to azimuthal equidistant is named aeqd: The printing of the image, not only does it look like a North Pole azimuthal equidistant projection, in fact it seems to be the same printed wikimedia image!
