Converting Incorrect Coordinates

Hi there

 

I'm hoping someone can help me with the following and that I haven't missed the same question somewhere else on this forum.

 

We are using ArcPad to undertake detailed geological and geotechnical mapping in one of our pits.  We are using coordinate system ED 1950 UTM Zone 37N.  The coordinates generated in ArcPad are consistently out by 6/7 metres for X/Y.  We have spent months exhausting all options with the hardware provider and we have contacted Esri tech support so see if they can provide a patch for correcting the coordinates on the device in ArcPad while we are mapping.  Unfortunately we have been told this can not be achieved. 

 

We are now wanting to amend the coordinates post data collection.  Is there an automated way of doing this in ArcMap?  Short of exporting to a .csv and adding 6 or 7 metres to the X or Y value then re-importing back into ArcMap we can not think of a way to achieve this.  Also, we only know how to do this for points, not for polygons (we need to shift the polygon/polyline in its entirety).  I guess we could convert polygons/polylines to a series of points using the ET Geowizard free add-on, export to excel, amend, re-import and re-build polylines/polyline from the amended points but this seems like a lot of work!  Surely there is an easier way???

 

Many many thanks in advance for any help.

 

Sophie
