ROADVEG - Maintenance Division, Roadside Vegetation

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 as needed. 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.

犹他州交通部（Utah Department of Transportation, UDOT）与犹他州立大学合作，开发了一款名为ROADVEG的关系型数据库与地理信息系统（Geographic Information System, GIS），该系统对道路两侧、毗邻区域及周边景观的土地与植被属性进行编码存储。道路段数据作为UDOT辖区内的基础命名与空间参照，涵盖道路段的区域编号、路线编号、行驶方向、起止里程桩号以及勘测日期。五组编码关系型数据字段，可为每个可变长度的道路段分配所属县、生态区、流域、地貌类型以及湿地属性。七组编码关系型数据字段对三类核心信息进行了摘要整理：(1) 道路红线范围内及邻近、大范围景观背景中的植被类型；(2) 道路红线植被与背景植被的等级相似性；(3) 乔木、灌木、草本这三大主要植被层的结构与整体组成。关系型数据表还提供了各编码植被类型对应的植被组成信息。所有被记录植物的学名、通用名、植物科属、起源属性，以及作为有害杂草、入侵物种或特殊保护物种的管理状态，均与对应植被类型相关联。用户可通过ArcView GIS界面按需查询并展示各类植被属性。截至目前，犹他州已有约1360线性英里的道路完成野外评估与评分。若获得后续资金支持，将对该州剩余主要道路开展普查工作。

该数据库的构建目标，是对道路两侧、毗邻区域及周边景观的土地与植被属性进行编码存储。
