But if you don't associate a projection to this geographic coordinate system, and naively render the coordinates as x/y coordinates on a grid, you do get something that is sort of a projection: the pseudo plate care ( equirectangular) projection. rev2023.3.1.43268. Thanks for contributing an answer to Stack Overflow! They use decimal numbers, not sexagesimal values. Your confusion probably stems from the fact that this coordinate system is based on an ellipsoid named WGS84 and a datum also named WGS84. All projected coordinate systems have the same behavious with distance measured from the map not being the same as distance along the ellipsoid's surface but usually the difference is not that big. Ellipsoid and datum are different in the sense that the ellipsoid defines the shape of the ellipse onto which the Earth is projected and that the datum defines where this ellipsoid "anchors" on Earth. engine. available in QGIS through the underlying Proj projection library. from shapely.ops import transform.
