Display XY coordinates at a designated location

JuanYao

Hi all,

I need to display a plume shape generated by a dispersion model into ArcMap at a designated place. The plume is shaped by points with  xy coordinated. I have imported these points into ArcMap as both dbf file and shape file. However, I have trouble locating the shape on the designated place. I have the lat and long of the origin for the layer. Could anyone please help me with this issue? Thanks!

Juan,

   If your dispersion model generated a point of origin with a full Lat and Long and the rest of the coordinates are just offsets for the point of origin, there is no easy way to add this like you would normally using  "Add XY Data" in ArcMap.

I have a Flex Viewer widget for Aloha plumes http://www.arcgis.com/home/item.html?id=06e2c33649c34c478a15dace967d0cdd That does this in the Flex Viewer.

"Add XY Data" is expecting a list of full coordinates, not offsets from a point of origin. You would have to script something to handle this.
