Undershoot: An arc that does not extend far enough to intersect another arc.
Undershoot A digitized line that does not quite reach a line that it should intersect. As with an overshoot, this is also sometimes referred to as a dangling line.

Undershoot: Situation where a digital line does not meet up with its intended boundary line. The space between the two is called a gap.
Undershoot - a topological error that occurs when an arc which is supposed to intersect with another arc fails to reach that arc. See also Overshoot.

Undershoots - An arc that falls short of its intersection point with another arc. A legitimate example of an undershoot is a road (line) segment that represents a cull de sac.
Crater Lake DEM, 20,000 iterations showing undershoot in the lake that is an artifact of the computation. This is a challenging file to interpolate.
Improving the appearance of scanned or digitized data by correcting overshoots and undershoots, closing polygons, performing coordinate editing, and so on.
during this topology generation process, problems such as overshoots, undershoots and spikes are either flagged for editing by the user or corrected automatically ...
Errors such as undershoots and overshoots must also be removed. For scanned maps, blemishes on the source map may need to be removed from the resulting raster. For example, a fleck of dirt might connect two lines that should not be connected.
In it, all lines are connected, there are no line overshoots or undershoots, and all feature on the display are representative of real-world features.
[quality control] Checking the accuracy of data before it is converted into a different format.
[quality control] Improving the appearance of data by closing open polygons, fixing overshoots and undershoots, refining thick lines, and so forth.
for example, that a network of lines represent a partitioning of the plane into a set of non-overlapping areas that collectively exhaust the plane, then it follows that the network can have no nodes of valency 1 (the dangling segments and undershoots ...
When creating the FMU polygon, it's not easy to eliminate slivers, dangles, or undershoots from shapefile, and it cannot be done in ArcView 3.x. Once you have added the topology to the coverage, you must convert it back to a shapefile.
