Dear David,
Apply following steps:
1-Take 1000,1000 as reference point and start plotting other points
2-Convert ur plot to rater file format
3-Import UTM projection with zone information
4-Georeference it with already available data sets, eg. toposheet matching GCPs with ur plot.
Hope i m able to explain it.
Bye

X, Y, and Z coordinates. I did not (naturally) record the north orientation
at the time and left the default X and Y coordinates to start with the
instrument at 1000, 1000. Okay. Dumb move. Now I need to plot that in a
GIS system that is using UTM Coordinates for Zone 14N, NAD 83. Of the
several hundred points I know the UTM coordinates of THREE. How can I
rotate the original points into the utm systems and plot them? The data are
(or soon will be) in a spreadsheet.
Here's a sample of what the data look like for the three points where I have
UTM coordinates for TS points:
Shot_Num Item_Num Grid_X Grid_Y Grid_ELev X_Coord
Y_Coord Zone NAD
49 117 1008.854 1009.658 99.71 245476 4114418 14
1983
54 116 1012.502 1007.601 99.815 245488 4114421 14
1983
113 139 985.108 1068.04 102.692 245476 4114442 14 1983
I do appreciate all help of any kind. Thanks.
Dave Hughes
