Route Typologies - Guide
Introduction and Outline (Part 1)
The architectural/geographical/cultural resources that are the focus of this nomenclature and discussion are predominantly "historical," i.e., more than 50 years of age. A better absolute closing date is World War II, which ended many architectural, structural and technological trends.
Example types and subtypes are linked to part of an online topographic map collection at TopoZone and will call up a topographic map in a new window showing the place.
Typological Outline
Focusing on a typology of routes in increasing detail and greater scale.
These are arranged with the first three distributed in Part 1, and the last in Elements / Part 3 .
-
Type-Families (or Master-Type, or Route Supertypes)
- General, larger scale characterization, beyond terrain.
- Approximate scale: county / scores of miles
- e.g. "Scioto River Route:" overall route through geological area / region
- Route Types
- Nomenclature and classification for general routes.
- Approximate scale: township / several miles
- e.g. "Terrace Route:" route segment with terrain
- Route Subtypes / Pathways~
- Three-dimensional paths that comprise a route.
- Approximate scale: section / 1 mile
- e.g. "Sideling Level:" identifiable part of a route, with landform
-
Route Elements
- Two-dimensional elements of direction or intersection of a route.
- Approximate scale: stone's throw
- e.g." Jog:" element in a route, analyzed only as it affects direction, without landform
