Undershoot
In vector data, an error where a digitized line does not extend far enough to meet another line at a node, affecting network connectivity and spatial analysis.
What is Undershoot known for?
A form of digitizing error known as an undershoot in GIS happens when a line feature does not extend far enough to meet another line with which it is intended to link. The line stops short, creating a tiny space between the two characteristics rather than meeting at a common point (or node).
Vector data frequently has undershoots, particularly when manually digitized or when importing data that has been inadequately edited. Disconnected lines may result in improper routing, flow analysis, or topological faults in networks like utility or road networks, which can cause issues with network analysis. Usually, topology checks or snapping tools in GIS software are used to identify and fix undershoots.

When a line in GIS stops short of joining another line, leaving a tiny gap, this is known as an undershoot mistake. Connectivity is impacted, and the line needs to be snapped or extended to rectify this.
Undershoot correction is the act of filling in the gaps in a GIS when lines that should cross do not meet, frequently as a result of low-resolution data or digitizing errors. By extending lines to correctly connect at nodes, this guarantees topological accuracy and avoids network or border errors in spatial studies.
Undershoot is a kind of digitizing error that happens in GIS mapping when a line feature is too short to meet another line at a node or intersection. This creates a tiny space between the two lines, which can lead to issues with geographic accuracy, network analysis, and topology validation.
Undershoots in GIS are when a line doesn't connect to another. Snapping tools, tolerance adjustments, or the application of topology criteria such as "must not have dangles to close gaps" can all be used to correct them.
