Dangling Nodes Are a Common Topological Error in Line Layers

Question

Examlex · Accepted Answer

The Answer is Dangling nodes are endpoints of a line that do not connect to other lines where they should, often occurring in geographic information system (GIS) data layers that represent linear features such as roads, utilities, or rivers. One possible cause of dangling nodes is incomplete digitization or data entry. During the process of converting analog maps to digital formats, or when manually creating or editing line features within a GIS, an operator may inadvertently fail to extend a line segment to meet another line segment, leaving an unconnected endpoint. This can happen if the operator is working with low-resolution imagery, if the source material is unclear or incomplete, or simply due to human error. Dangling nodes can also result from data import errors or when integrating datasets from different sources that may not have the same level of precision or connectivity standards.
