The Utah Department of Transportation, in collaboration with Utah State University, developed a relational database and GIS, dubbed ROADVEG, that encodes land and vegetation attributes for roadsides, adjacent lands, and context landscapes. Road segment data constitute the basic nomenclatural and spatial references to the UDOT region number, route number, travel direction, from and to mile-markers, and survey date for the road segments surveyed.
Five fields of coded relational data assign county, ecoregion, watershed, landform, and wetlands attributes to each variable-length road segment.
Seven fields of coded relational data form an abstract of (1) the vegetation types along the right-of-way and in the nearby and greater landscape context; (2) the ranked similarity between the right-of-way vegetation and the context vegetation; and (3) the structure and general composition of the three primary vegetational layers - trees, shrubs, and herbs. Relational tables also provide vegetational composition for encoded vegetation types.
Scientific names, common names, families, origins, and management status as a noxious weed, invasive species, or special status species, are also related to vegetation types for all plants encountered. Via the ArcView GIS display, users are able to query and display various vegetational attributes asneeded. To date, about 1,360 linear miles of Utah roadways have been field-assessed and scored. As funding becomes available, the remainder of the state's major roadways will be inventoried.
The purpose of the database is to encode land and vegetation attributes for roadsides, adjacent lands, and context landscapes.
