Hi,

I'm trying to create a new point layer from some Lat and Long coordinates that I have in a table (exp. 44.809662,-73.087322

). I used "Make New XY Event Layer" to plot the points. I have some town parcel layers and the point locations are all from within the parcels so the new point layer should be overlapping the parcels. However, they aren't even close!! I thought it might have been my Lat Long Coordinates so I took Lat Long coordinates from five random locations in the area using Google Maps, imported them into ArcMap as an Excel file and tried again. They all showed up really far away also! Their spatial spread looks correct but they aren't close to the parcel layers.

The projection system and the coordinate systems are the same so I'm not sure what's wrong. Any ideas?

Thanks,

Alan

I can think of two possibilities. Are you equating X = longitude and Y = latitude?

When using the Add XY tool, you need to assign the data's current coordinate system. The tool will default to the data frame's coordinate system. Because your points are in lat/lon, you need to assign the appropriate geographic coordinate system.
