Creating new XY data within a plot from UTM coordinates

[MichaelJust]

Hello,

I have several rectangular plots (shapefiles) in which I have several points (shapefiles).  I have the XY data (UTM) for the points.  I understand that UTM data is XY, but I would like to know the point locations within the plot ("the plot's XY").   For example, one of the plot's corners would become the new origin for my "PLOT XY."  Can this be done in ArcMap? And if not, what should I be reading about / searching for to complete this operation?

Thank you kindly,
Mike

My suggestion would be this:

1. Create a new point shapefile, add it to the map and create a point at the maps origin
2. Add data to bring your rectangle and point shapefiles
3. Start an edit session and then select your rectangle and points so that they are all selected at once
4. Drag the corner of your rectangle that you want to be at the maps origin and snap it to the point created in step 1
5. Save edits
6. Create 2 new fields in your point shapefile as short, called ColumnX and ColumnY or something like that
7. Right click on the column and calculate geometry for X and Y based on which every projection you desire (the shapefiles projection or the dataframes projection)

Thank you for the quick reply. Attempting the procedure now.

Hello,
Unfortunately you can't rotate point shapefiles in editor.  Thanks for the suggestion.

Cheers,

1.) Create Minimum Boundary Geometry, rectangle by width or area (may be different), and place in the same geodatabase as your points
2.) Start editing your points
3.) Select all of the points you want to rotate
4.) Use the Rotate tool to rotate the selection (I think you'll have to eyeball when it gets horizontal)
