I am new to ARCGIS 3.4, and entirely self-taught. I have a well location database. I have determined that a number of the wells have bad UTM coordinates. I have found the original survey locations in aliquot. It has then been possible to use the edit function and move the well symbol to the correct location. However the attribute table does not change coordinates. I would like to replace the old coordinates. I am not sure how to go about this.
