ArcGIS 10 (Desktop) not displaying CSV datapoint

Question

Hi all,

I can't seem to get the attached CSV data points (which are Decimal Degree coordinates) to display on my map file (also attached). I've tried playing around with the long/lat columns, changing the projected system, and all to no avail. Really quite stuck now, so would be very grateful for some clarity as to where I'm going wrong.

Thanks!

Hi Calum,

When you added the xy data, you set the coordinate system to OSGB36? Or WGS 1984?

Ah, the longitude and latitude fields in the csv files are swapped. The -1 values should be labeled longitude and the 51 values are the latitude values.

If the OA data is really in British National Grid, you should set a transformation. Open data frame properties, coordinate system tab, transformations button.

Hi abdallah_91@yahoo.com‌

Apologies for my delay in replying. Unfortunately, this still isn't working. In terms of what I've done, I have:

1) Imported the geographic entity (here, OA layer)

2) Added data (XY data) and defined the Long/Lat

3) Ensured that the projections are the same (using the Project tool)

However, the data does not display at all. What else could be happening here?

Thanks again for all of your help! It's really appreciated.
