In Oasis Montaj (Geosoft), I chose the Mexican Datum of 1993 as the geographic coordinate system, but I also need to use a projected coordinate system (in order to do the analysis, Oasis Montaj needs to have grid coordinates) and I'm not sure which one to use?</P><P>Thank you!</P> Wed, 17 Mar 2021 19:19:32 GMT https://community.esri.com/t5/arcgis-community-analyst-questions/coordinate-system-in-mexico/m-p/1037767#M217 bdaoust6 2021-03-17T19:19:32Z https://community.esri.com/t5/arcgis-community-analyst-questions/coordinate-system-in-mexico/m-p/1037854#M218 <P>It would be wise to connect with Geosoft support for working on Oasis Montaj.</P><P>But let's assume you have the GIS Dataset in ArcMap/ArcGIS Pro.&nbsp;<span class="lia-unicode-emoji" title=":winking_face:">😉</span></P><P>You may choose to convert it to</P><P>Projected Coordinate System:&nbsp;<EM>WGS_1984_Web_Mercator_Auxiliary_Sphere (WKID:3857)</EM></P><P>Transformation Method:&nbsp;<EM>Mexican_Datum_1993_To_WGS_1984_1</EM></P> Wed, 17 Mar 2021 22:18:42 GMT https://community.esri.com/t5/arcgis-community-analyst-questions/coordinate-system-in-mexico/m-p/1037854#M218 JayantaPoddar 2021-03-17T22:18:42Z
