GROUP: transportation (tr)
DEFINITION: transportation. Roads, highways, etc.

1. Object
   1. local roads, paths, & access = includes all local roads, paths and access built for transport within local areas, with no high-speed (>65 km/h; 40 miles/h) sections.
   2. local highway = roads built for long-distance transport, mostly high-speed (>65 km/h; 40 miles/h), but often including intersections with full stops.
   3. railroad bed
   4. bridge (>2m) = transportation across water, with water surface underneath.
   5. high-speed highway = roads built for high-speed (>65 km/h; 40 miles/h) long distance transport that do not include intersections with full stops.
   6. overpass (>2m) = sealed transportation surface covering non-water features. These may include many types of features ranging from Constructed to Perennial.
2. Modifier 1 (structure type)
   1. paths, roads & access
      1. unpaved = unimproved roads (local earth)
      2. paved = improved roads (sealed or filled with rock)
3. Scale (of building footprint)
   1. local roads, paths, & access
      1. wide >2 m

1. local roads, paths, & access
   1. unpaved
      1. wide >2 m = tr01
   2. paved
      1. wide > 2m = tr02
2. local highway = tr03
3. railroad bed = tr04
4. bridge (>2m) = tr05
5. high-speed highway = tr06
6. overpass (>2m) = tr07

1. IF TYPE with greater area is very similar or otherwise unclear:
   1. Choose unpaved over paved.
2. IF paralleled by a <2 m irrigation feature, and unclear which has greater width or feature area:
   1. Choose transportation over irrigation.
3. IF unclear whether a field border or other anthropogenic boundary or earthwork is used as a path (tr01) or is just a disturbed feature (significant vegetation growth, etc.):
   1. Choose disturbed & debris over transportation.
