Be aware that most of the time you dont have to set a projection. It is true that near the poles length measurements in EPSG:3857 give results which do not match at all with ground truth. 2 0 obj One of: Leave as unknown CRS (take no action): QGIS has support for approximately 7,000 known CRSs. If you are not using the data for web mapping, I would strongly encourage you to consider some other projection that is more suitable to your use-case, especially if you intend to do distance calculations (or, in that event, cast your data in geographic coordinates and not Cartesian coordinates and use the Haversine formula to calculate distances on a sphere). Connect and share knowledge within a single location that is structured and easy to search. specify the EPSG code using the init proj4 string: The above will now raise a deprecation warning from pyproj, and instead of the Click on Calculate, and compare the The page for the unit is https://epsg.io/9122-units, which clarifies by saying "The degree representation (e.g. Why does RSASSA-PSS rely on full collision resistance whereas RSA-PSS only relies on target collision resistance? In QGIS, on-the-fly CRS transformation is enabled by default, meaning that As a consumer of the data it means you need to be able to parse whichever format is used or have prior knowledge of the format used. a CRS object: You notice that the above is a not a Projected CRS as expected, but a Bound CRS. latitude-longitude CRS to the GeoSeries.set_crs() method (or by setting the GeoSeries.crs attribute): Re-projecting is the process of changing the representation of locations from one coordinate system to another. you didn't mention the data type in the question.

So this can be seen as a technical decision rather than a definition. Also compatible CRS objects, such as from the rasterio package, can be How to add meters to EPSG:4326 coordinates? Thanks for contributing an answer to Geographic Information Systems Stack Exchange! EPSG:4326 (WGS84) The World Geodetic System of 1984 is the geographic coordinate system (the three-dimensional one) used by GPS to express locations on the earth. As the size of a degree is variable depending on the location in the world, this does not make much sense. 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.
