In QGIS, on-the-fly CRS transformation is enabled by default, meaning that endobj instance, the common WGS 84 latitude/longitude CRS is known by the identifier when reprojecting instead of letting PROJ determine the best conversion. For some CRS, there are a number of possible When taking one of those definitions from that site, and creating QGIS behavior whenever it cannot automatically determine the correct CRS for a How to properly visualize the change of variance of a bivariate Gaussian distribution cut sliced along a fixed variable? are based on those defined by the European Petroleum Search Group (EPSG) Setting a projection is how one tells geopandas how to interpret coordinates. ALso as it says in the ST_DWithin page: Returns true if the geometries are within the specified distance of one another. As you can see 4326 is the EPSG code representing WGS84, so yes they are the same. Openlayers has the ability to project your webmap to any coordinate system, and I believe this example is showing how to do that given any of the data storage coordinate system issues noted above.
