Looking at the SDE documentation, I am surprised it does not look possible to select an output unit in geodesic meter, kilometer, miles... as in the ST_Distance function.</P><P></P><P><A class="link-titled" href="https://desktop.arcgis.com/en/arcmap/latest/manage-data/using-sql-with-gdbs/st-length.htm" title="https://desktop.arcgis.com/en/arcmap/latest/manage-data/using-sql-with-gdbs/st-length.htm">ST_Length—Help | Documentation</A>&nbsp;</P><P></P><P>Is there any workaround? It look like there is a possibility with the ST_Transform on the fly. However, as soon as you transform geodesic data into planar data, there will be some sort of errors introduced because my dataset is global.</P><P></P><P>Any help will be appreciated.</P></BODY></HTML> Wed, 08 Apr 2020 16:34:27 GMT https://community.esri.com/t5/geodatabase-questions/st-length-units/m-p/848130#M5098 VincentLaunstorfer 2020-04-08T16:34:27Z Re: ST_Length units? https://community.esri.com/t5/geodatabase-questions/st-length-units/m-p/848131#M5099 <HTML><HEAD></HEAD><BODY><P>Adding a broader audience: <A href="https://community.esri.com/group/1680">Geodatabase</A>‌</P></BODY></HTML> Wed, 08 Apr 2020 17:27:53 GMT https://community.esri.com/t5/geodatabase-questions/st-length-units/m-p/848131#M5099 George_Thompson 2020-04-08T17:27:53Z Re: ST_Length units? https://community.esri.com/t5/geodatabase-questions/st-length-units/m-p/1122942#M7450 <P>Hi George, a while ago, you managed to forward my question above to a broader audience... How to you do that? Is there topic completely transferred to the more targeted community that way?
