https://community.esri.com/t5/arcgis-api-for-python-questions/convert-sdf-to-wgs-84/m-p/1100186#M6672 <P>Hi, I have an sdf from a feature layer in the&nbsp; EPSG 5514 coordinate system, and it returns points with coordinates in meters. After applying a query where I call "out_sr=4326" at the end, I get the coordinates in degrees, but they are a bit off by a few meters. Is there another way to trnsform the coordinates or the whole sdf into 4326? thanks</P><P>&nbsp;</P><LI-CODE lang="python">sdf = znacky.query(where="NAPIS like '%=invalida%' or OZNACENI like '%IP12O%' or NAPIS like '%= invalida%' or NAPIS like '%X invalida%' or NAPIS like '%x invalida%' or NAPIS like '%.invalida%' or NAPIS like '%. invalida%' or NAPIS like '%.invalida%' or CISZN like '%IP1201%' and platnost_t not like '%Archiv%'",out_sr=4326 ).sdf</LI-CODE> Tue, 21 Sep 2021 06:24:57 GMT JiříKomínek 2021-09-21T06:24:57Z https://community.esri.com/t5/arcgis-api-for-python-questions/convert-sdf-to-wgs-84/m-p/1100186#M6672 <P>Hi, I have an sdf from a feature layer in the&nbsp; EPSG 5514 coordinate system, and it returns points with coordinates in meters.
