15012001adj.jpg (12657 bytes) Adjusts or rubber sheets a polylines from a theme in direction along the links from a  link theme

For description of Edit Theme, Snap Theme and Link theme see Edge Match.

The procedure builds a TIN surface from the links in the link theme and interpolates the transformation vectors for each polyline vertex from the edit theme, then the vertices are transformed with the displacement vectors interpolated.

NOTES:

  • It is important the links to be spread systematically over the entire theme including along the outer edges.
  • The further away a coordinate is from a link, the less effect that link has on the coordinate’s adjustment.
  • In some cases Adjust function gives better results  for Edge Matching than the   EdgeMatch function

One of the major uses for ADJUST is to perform datum conversions. In this case the link theme can be imported from a table containing the coordinates of  the control points
