Postgis, get the points that are x meters near another point, in meters, postgis st_buffer + defining coordinate system. Introduced in 1.5 support for Truce of the burning tree -- how realistic? If I do the exact same thing in a GIS (ArcGIS Pro) with the EPSG 4258 layer and a buffer with 5 kilometres the output is still in the 4258 coordinate system, so I wonder if the Arc GIS workflow is not correct then, because if what you say is true, the buffer tool should reproject it right?, but this is not the case, this is very confusing to me. I did exactly what you did and then changed. This is a shortcut for ST_PointN(geometry, ST_NumPoints(geometry)). returns the geometry at a given index. from GPS tracklogs.

Implementation Specification for SQL 1.1. s2.1.1.3, This method implements the SQL/MM specification. if the input geometry is not a multi-geometry. Calculate a buffer around all cells that are not NA or around SpatialPoints, Lines, or Polygons. A negative distance shrinks the geometry rather than expanding it. If the given index is less than 1 or greater than the total number of elements in the collection, privacy statement. e.g., is it from the centre of the polygon? Returns a geometry that represents the point set union of the input geometries. Returns the spherical geography type object from the GeoJSON representation stripping non geometry key/values. Your example is on the equator, but with realistic examples anything further away will have direction-dependent buffers when treating ellipsoidal coordinates as Cartesian (the GEOS way).

'mitre_limit=#.#' : mitre ratio limit (only affects mitered join style). 1 Hello I used the ST_Buffer to set a 5 kilometre buffer with this code: CREATE TABLE Buf_5km_Schiff as SELECT ST_Buffer (geom, 0.05) FROM public."Input_Schifffahrtswege"; It works but im not sure why I need to set 0.05 for 5 kilometres. For geography, this is a wrapper around the geometry implementation. First thing that makes fail all what you have tested is inversion of X and Y coordinates, 'POINT( 339298.446287788 7391719.02695803) should become 'POINT ( -46.57464981079102 -23.5770487595231 )' and not 'POINT ( 23.5770487595231 -46.57464981079102)' like in your sample, Or by going to https://epsg.io/transform#s_srs=31983&t_srs=4326&x=339298.4462878&y=7391719.0269580 (PS: longitude is X and latitude is Y).
