A library of software components that make up the foundation of ArcGIS. This library is referenced in Visual Studio for development of the GIS-specific functions that make the Curvature Extension work.
A curved line that is a section of a circle, with two vertices, one situated at each endpoint. The Curvature Extension, using ArcObjects, creates a circular arc based the user-defined curve. The radius of the circular arc is then used to derive the curve classification.
A designation (A - F) assigned to a curve based on its radius. A curve class of A indicates a broader curve, while a curve class of F indicates a sharper curve.
The digitized direction of the curve in the route system.
Highway Performance Monitoring System. A report to the Federal Highway Administration (FHWA) using the General Interest Roadway Data and other data to describe public road conditions and performance.
A record from the HPMS GIS layer that represents an HPMS sample.
For the Curvature Extension, a GIS layer of roads used to derive curve classification.
