The discussion at What is the difference between WGS84 and EPSG4326? shows that 4326 is just the EPSG identifier of WGS84.. Wikipedia entries for Google Maps and OpenStreetMap shows that they both...

Feb 5, 2021 · How does one definitively identify the EPSG that goes with the projection content given in LiDAR metadata when the metadata omits the EPSG code? If the content in the above metadata and that of any EPSG code all match, does it …

Oct 14, 2024 · I am new to EPSG and QGIS. I want to Georeference a Raster image to EPSG:5235 in QGIS but I can't find above EPSG. How do I add this EPSG to QGIS?

May 2, 2021 · Some sources say that WGS 84 and EPSG:4326 are exactly the same things, others say they are different, but they don't provide the differences. How should I be writing down the longitude and latitude in the EPSG:4326 CRS system?

Feb 16, 2021 · EPSG 4326 (i.e. WGS 84) is not a projection. 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 carée (equirectangular) projection.

Nov 11, 2021 · I measure distance (km) in QGIS (Ctrl + Shift + M) . In Ellipsoidal, it using CSR EPSG:7030. In Cartesian, they didn't say what projection is used. If it using ellipsoidal option, does it mean measured using great circle formula in ellipsoid model? If it using projection, what projection it used?

Jun 2, 2017 · Instead, if EPSG:3857 would be in meters as such, the calculation would just be with Pythagorian sqrt (dx^2 + dy^2). - But that kind of coordinate system is actually not possible, as the Earth is a sphere.

Mar 14, 2021 · Inspecting the EPSG codes on epsg.org, I see that these three datum have three different ellipsoids. Therefore, I expect to get different results for p and p1 since I do observe a difference between p and p2.

Nov 15, 2021 · What is the difference between WGS84 and EPSG 4326? It seems like for a given dataset it might be both WGS84 and EPSG:4326.

Dec 16, 2022 · Provided the input EPSG is truly 3857, this should be a case of: myProj = Proj(epsg) X, Y = myProj(lon, lat) However, I think it is important to understand a bit more about EPSG:3857. This would be a somewhat strange projection for this file to be in. Typically, this is a projection only used by Google Maps, Bing, Open street map.
