Direct Download (Raster Data Gateway)Objective: Identify locations where roads are present at a density that impacts the quality of wildlife habitat and fragments the landscape.Data: A national roads vector dataset has been acquired from the USGS National Transportation Dataset. The data were reattributed to represent three classes: (1) Unimproved, (2) Paved, (3) Light Duty roads. The new classes correspond to the following classes from the National Transportation Dataset:Unimproved: Four-wheel drive roads.Paved: Controlled access highway, Secondary Highway or Major Connecting Road, RampsLight Duty: Local Connecting Roads, Local RoadsData Format: Polylines were converted to a raster for each TCA assessment year. The value at a pixel corresponds to the class of road at that location. Values differ slightly between the years:2024: 1- Light Duty, 2- Paved, 3- Unimproved, 4- Other2023: 1- Light Duty, 2- Paved, 3- Unimproved, 4- Other2022: 1- Light Duty, 2- Paved, 3- Unimproved2021: 1- Light Duty, 2- Paved, 3- Unimproved2020: 1- Light Duty, 2- Paved, 3- Unimproved, 4- Other, 5- DecommissionedSpatial Resolution: 10mSource data: USGS National Transportation DatasetAdditional Resources:Details on Method Changes and Source Data VersionsOverview of the Terrestrial Condition Assessment: TCA Hubsite or Landfire Office Hour PresentationExplore the results of the most recent assessment: TCA Interactive Data ViewerLearn more about the TCA KPI: TCA Dashboard*if you have trouble viewing the Dashboard, please submit a Tableau Viewer Access RequestThis record was taken from the USDA Enterprise Data Inventory that feeds into the https://data.gov catalog.

研究目标:识别道路密度达到影响野生动物栖息地质量、并造成景观破碎化的区域。
数据说明:从美国地质调查局(USGS)国家交通数据集获取国家级道路矢量数据集。对该数据进行重新属性标注,划分为三类道路:(1) 未铺装道路,(2) 铺装道路,(3) 轻型道路。新分类对应国家交通数据集的以下类别:
未铺装道路:四驱车通行道路。
铺装道路:受控出入高速公路、次级公路或主要联络道路、匝道。
轻型道路:本地联络道路、地方道路。
数据格式:针对每一个陆地状况评估(Terrestrial Condition Assessment, TCA)年度,将多段线矢量数据转换为栅格数据。每个像素的像素值对应该位置的道路类别,不同年度的像素值略有差异:
2024年:1-轻型道路,2-铺装道路,3-未铺装道路,4-其他
2023年:1-轻型道路,2-铺装道路,3-未铺装道路,4-其他
2022年:1-轻型道路,2-铺装道路,3-未铺装道路
2021年:1-轻型道路,2-铺装道路,3-未铺装道路
2020年:1-轻型道路,2-铺装道路,3-未铺装道路,4-其他,5-已废弃道路
空间分辨率:10米
