I am trying to display gINT points in ArcGIS and am unsure of the units and datum I should use when populating our easting and northing columns.
I figured that I would use UTM-- and the points display o.k. in arcmap in terms of location relative to one another but are well offset from my actual study area, no doubt due to some UTM zone correction or something. Should I be doing this differently?
Any tips on this?
Hi. Assuming that the coordinate system information is not stored in gINT, you will need to know in what coordinate system your gINT points were entered in the database and configure ArcGIS to use the same one.

Thanks for the reply! I did make sure that the coordinates I entered into gINT were indeed in the coordinate system and datum used in my data frame in ArcGIS, but after opening the gINT file in ArcGIS, they appear shifted still.
I know the coordinates are correct via Google Earth and also separately plotting them in ArcGIS. Is there some transformation that gINT is doing to the data? Is gINT assuming that I entered the coordinates in some particular format, and shifting them to conform with my ArcGIS dataframe?
Can you quantify the shift you're talking about ? Is it always a fixed distance, or possibly a constant factor ?
