I tried the feature to point tool and couldn't get it to work, ie place a point in the center of the multipoint features. I input 3 points in a feature class, "points", and left the box in the tool unchecked. The tool created 3 points, but they are all just coincident with the original points; it did not set a point in the center of the 3 points, as I expected and need it to. I hope someone can tell me what I'm doing wrong. I also tried it with the box checked.
However, encouraged by the Wayne and Tish's comments, I did some trial and error and would like to throw these procedures out to the community to comment on. I'd still, really, like to find out the way to use ArcGis to make a least squares or similar weighted average of a set of point.
Procedure to adjust a traverse to remove error indicated by a tie in with a survey monument. Finding and changing a bad bearing or distance.
ArcInfo license/COGO toolbar and list of traverse bearings (deg min seconds or dec degrees format) & distances required. Create a line feature [the cogo tool req a line feature to create a traverse] �?? start editing the line feature �?? editor options �?? set to north azimuth & dec degrees �?? activate the COGO traverse tool - set the start point �?? enter all of the traverse shots, ending at the tie to the survey monument �?? right click on a traverse entry, in the traverse window, that you believe has an inaccurate bearing or distance �?? properties �?? change the bearing or distance [ this will adjust the whole traverse] �?? evaluate how much closer the end of the traverse is to the tied survey monument �?? repeat with other traverse shots until you�??ve eliminated as much error as possible and the end of the traverse is as close to the survey monument as poss. When it�??s close enough to the survery monument finish the traverse.
Procedure to adjust a series of side shots to a corrected traverse. These are side shots made off of the original traverse, as adjusted above. Set a point at the end of the adjusted traverse, the point nearest the survey monument �?? create a feature class of all of the side shot points you think need to shift �?? start editing the feature class �?? set snapping to vertex - Select all of the side shot points �?? use the editor tool to drag the side shot points onto the traverse point
