Different spatial reference issue with Geoprocessing in leaflet

A_S_ — Mon, 28 Aug 2023 13:17:43 GMT

Hi, I’m building a web map with ArcGIS Server, Leaflet and Esri-Leaflet.

Now I’m trying to add a standard geoprocess out of the ArcToolbox (Select Layer by Attribute) but I’m having a problem with the output spatial reference system.

All my data on the Server is in ETRS_1989 and for the web map its transformed into EPSG 4326. Starting my geoprocess replays me data in ERTS_1989, so I changed in ArcMap the “Output Coordinates” in Environment Settings before publishing the service, but that didn’t change anything, services still replays in ERTS_1989.

The only way to change that behaviour is using the ArcGIS Server Manager via my browser, guide through Home > services > SelectLayerByAttribute (GPServer) > Select Layer By Attribute > subitmitJob to: Options – Output Spatial Reference and write down 4326 there. This allows me to get back data in 4326 for all future tasks, but only for that one layer I was asking for, all other layers still replay with ETRS_1989.

So is there a way how I can handle that problem? Because I don’t want to change the output spatial reference for each layer by hand using the browser server manager.

Do I have to do something more as described above before publishing that service or is there a way to change output coordinate system with leaflet? I saw that there is a method in ArcGIS Java Script API but I didn’t see something similar in Esri-Leaflet.

Thanks for your help in advance. Let me know, if you need more information to help me.

can you publish a simplified public GP service (perhaps with dummy data) and share some steps to get it to return data in both coordinate systems please? that would really speed up troubleshooting.

Thank you for your fast answer. I'm not a server admin and after requesting to publish a public GP service I'm not allowed to do this. Would it be helpful to load some screens of GP creation? Maybe I forget only a button or something else. Anyway, if you have tips or ideas for trouble shooting this would be also helpful for me.

Thank's for your help, but I have the solution. Damn!! Didn't know that there is a simple way by using: gpTask.setParam('env:outSR', 4326);
