I am trying to plot points off the coast of the Northeast Atlantic Coast, and they are ending up off the coast of Ghana. I've tried importing from a csv file and an excel spreadsheet. I attached a sample of my data.&nbsp; </P><P></P><P>I know the western hemisphere longitude values must be negative and northern latitude values must be positive. Any other reason why I am not plotting these points correctly?</P></BODY></HTML> Tue, 20 Oct 2015 15:32:19 GMT https://community.esri.com/t5/arcgis-mapping-and-charting-questions/latitude-and-longitude-coordinates-in-wrong/m-p/174877#M591 MorganCunningham 2015-10-20T15:32:19Z Re: Latitude and Longitude Coordinates in Wrong Hemisphere https://community.esri.com/t5/arcgis-mapping-and-charting-questions/latitude-and-longitude-coordinates-in-wrong/m-p/174878#M592 <HTML><HEAD></HEAD><BODY><P>Are you correctly defining which is X and Y.</P><P>Longitude = X; Latitude = Y</P></BODY></HTML> Tue, 20 Oct 2015 15:39:35 GMT https://community.esri.com/t5/arcgis-mapping-and-charting-questions/latitude-and-longitude-coordinates-in-wrong/m-p/174878#M592 NeilAyres 2015-10-20T15:39:35Z Re: Latitude and Longitude Coordinates in Wrong Hemisphere https://community.esri.com/t5/arcgis-mapping-and-charting-questions/latitude-and-longitude-coordinates-in-wrong/m-p/174879#M593 <HTML><HEAD></HEAD><BODY><P>Are you specifying a coordinate system?&nbsp; You should probably be using GCS_WGS_1984.&nbsp; I tested with your data and it worked correctly.&nbsp; If you are not sure what I mean, just ask.</P></BODY></HTML> Tue, 20 Oct 2015 15:41:50 GMT https://community.esri.com/t5/arcgis-mapping-and-charting-questions/latitude-and-longitude-coordinates-in-wrong/m-p/174879#M593 GabrielUpchurch1 2015-10-20T15:41:50Z Re: Latitude and Longitude Coordinates in Wrong Hemisphere https://community.esri.com/t5/arcgis-mapping-and-charting-questions/latitude-and-longitude-coordinates-in-wrong/m-p/174880#M594 <HTML><HEAD></HEAD><BODY><P>Yes I am, when I plotted the exported data I put the longitude as X and latitude as Y. </P></BODY></HTML> Tue, 20 Oct 2015 15:42:19 GMT https://community.esri.com/t5/arcgis-mapping-and-charting-questions/latitude-and-longitude-coordinates-in-wrong/m-p/174880#M594 MorganCunningham 2015-10-20T15:42:19Z Re: Latitude and Longitude Coordinates in Wrong Hemisphere https://community.esri.com/t5/arcgis-mapping-and-charting-questions/latitude-and-longitude-coordinates-in-wrong/m-p/174881#M595 <HTML><HEAD></HEAD><BODY><P>Okay!
