All Mercator-style projections have the same defect as they move away from their reference point. It doesn't have to be exact, just a rough hueristic figure. They use decimal numbers, not sexagesimal values. There are many much better alternatives. This default CRS is EPSG:4326 (also known as WGS 84), and it is a global GeoSeries by hand, you would set the projection by passing the WGS84 This means approximately a square of 40,000 x 40,000 kilometers. For geometry units are in those of spatial reference and For geography units are in meters and measurement is defaulted to use_spheroid=true (measure around spheroid),. may have its own specific set of transformations specified via the Choosing an appropriate reference See 3D CRS for original information source.

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. Some coordinate systems have zones (like the one in example above), so before you reproject your data you have to know the zone number. and how to enable it on your system. 1 degree of latitude corresponds to 111km 1 degree of longitude corresponds to 73km Thus, to get the point located 100 meters Eastern to your original point, you can add 73m*1/80km ~ 0.001 of longitude. the user manual and are the same as those used by QGIS. your code. latitude-longitude CRS to the GeoSeries.set_crs() method (or by setting I'm pretty new to GIS and I've learned about both the geographic coordinate system, which defines a location on a 3d model of the world and the projected coordinate system to map this to a 2d surface and I thought I had a decent grasp of it.
