Automated Linework Reconstruction
The example drawing has an area of "dashed"
contours which are really broken linework fragments (in magenta). We want to
Join these fragments to the regular contours (only if they have the same
Elevation).
There are also large gaps in the contours (probably where
labels used to be). We want to close these gaps with Join.
After the
Contours have been joined, we want to Find the 1000 foot contours and
Change the Layer to Index, then Label them and Clip the
underlying linework and change it's layer (so it can be turned off for
plotting).
A new Treeline has been digitized (in green) but there are
large gaps and it's not very smooth. We want to Join it,
Close it, Smooth it using NURBS fitting (passes through every
point) and then optimize it with Curvefit (to reduce the number of
vertices).
A walking path has been sketched (in gold). We want
to Smooth and Optimize it and then Symbolize it with a
hiker symbol and a direction arrow.
We can easily create an
"instruction set" and make a custom command to accomplish ALL of these tasks
with a Single Pick, using MapTools Commander. The new LW_RECON command
uses 8 of the 18 automated processors included with MapTools Pro: PET,
PolyClose, Join, Clip, PNURBS (polyline smoothing), Curvefit, Label Linework
and Automatic Text Alignment.
Our new automated routine performs 35
operations with a Single Pick. We can process the current drawing OR we can
apply the same process to a group of drawings Unattended. |
