Adding X,Y data to a shapefile with existing X,Y data

JaredReid1 — Mon, 16 Jul 2012 17:01:51 GMT

I have a shapefile with X and Y data plotted on my map. I want to be able to add additonal points to the attirubte table and have it update on my map immediately. Is that possible without running the "Add XY Data" option?

Jared,

If you have already created a shapefile from X,Y data then the only way you can add more points to it is in an editing session. You can use absolute x,y to add the point to exactly where you want it. You can then reverse engineer the coordinates to the feature table using calculate geometry by right clicking on the field name in the attribute table.

As far as I am aware you cannot just add extra rows to the attribute table as they have to be associated to a geometrical feature that has to be drawn.

Are the new points in a different table? You'll need to use the tool to create geometry for the new points, but to automate the process, you can create a model to run the Make XY Event Layer tool, then use the Append tool to append the output to your existing XY data layer.

I simply want to edit my attribute table and type in a new xy coordinate and have it display on my map.

Jarid,

This cannot be done

I simply want to edit my attribute table and type in a new xy coordinate and have it display on my map.
