Hello,
I have a problem to define the projection of my XY data :
Here bellow are my XY data of location in Scotland
[ATTACH=CONFIG]34173[/ATTACH]
On arcgis I : add data => display XY data => Projected Coordinate System: Name: British_National_Grid Geographic Coordinate System: Name: GCS_OSGB_1936
[ATTACH=CONFIG]34174[/ATTACH]
then I Export data and I get this
[ATTACH=CONFIG]34175[/ATTACH]
This layer have this Data Source :
Projection: Transverse_Mercator
False_Easting: 400000.000000
False_Northing: -100000.000000
Central_Meridian: -2.000000
Scale_Factor: 0.999601
Latitude_Of_Origin: 49.000000
Linear Unit: Meter (1.000000)
Geographic Coordinate System: GCS_OSGB_1936
Angular Unit: Degree (0.017453292519943299)
Prime Meridian: Greenwich (0.000000000000000000)
Datum: D_OSGB_1936
Spheroid: Airy_1830
And then I would like to add a polygon layer of Scotland :
Data Type: Shapefile Feature Class
Shapefile: C:\Users\77780575\Desktop\Arcgis\Scotland Country Boundary\Scotland boundary.shp
Geometry Type: Polygon
Projected Coordinate System: British_National_Grid
Projection: Transverse_Mercator
False_Easting: 400000.00000000
False_Northing: -100000.00000000
Central_Meridian: -2.00000000
Scale_Factor: 0.99960127
Latitude_Of_Origin: 49.00000000
Linear Unit: Meter
Geographic Coordinate System: GCS_OSGB_1936
Datum: D_OSGB_1936
Prime Meridian: Greenwich
Angular Unit: Degree
My XY data are not matching with the polygon layer as you can see here bellow

I think the problem come from the part in bold. Have you an idea ? Thank you.
I use ArcMap 10, Windows 7, Excel 2010
