Move Points Onto String

This allows the user to move surveyed points onto the road centreline.

This Option changes E/N/H co-ords of points!

Road String
Select the road string with the mouse, the name will be displayed

Select Points layers
This option allow you to select point by group, layer etc.
These are the points which will be moved onto the string.

Max Dist from String
Points further than this distance (perpendicular) will not be moved.

Option

1 - No height values will be changed on Moved Points, or any other Points.
2 - If a Moved Point has no height, it will be interpolated from the String pts. This depends on the String Points having height values
3 - All Moved Points will have height values interpolated from the String pts.
This replaces the Moved Point height value (if any) with the interpolated height value from the String.
This depends on the String Points having height values
