Dynamic Segmentation
Definition
Dynamic Segmentation is a GIS technique that allows the representation of multiple attributes along a linear feature without physically splitting it into segments. It links tabular event data to portions of linear features based on location measures such as distance or mileposts, commonly used in transportation GIS.
Application
Departments of transportation use it to manage road attributes like speed limits, pavement conditions, and accident data. Utilities track cable condition, maintenance, and outage zones along power lines. GIS tools like ArcGIS support event tables and route creation to perform linear referencing and query events dynamically.
FAQ
What problem does dynamic segmentation solve?
It allows multiple data attributes along a line without splitting the feature into many geometries.
How is it used in transportation?
To associate events like accidents or speed zones with highway segments based on mile markers.
Which data format supports dynamic segmentation?
Route-event tables and linear referencing systems in GIS.
Who uses dynamic segmentation?
Transportation departments, utilities, pipeline managers, and infrastructure analysts.
