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:</p><ol><li>Unimproved: Four-wheel drive roads.</li><li>Paved: Controlled access highway, Secondary Highway or Major Connecting Road, Ramps</li><li>Light Duty: Local Connecting Roads, Local Roads</li></ol><p><strong>Data Format:</strong> 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:</p><p>2024: 1- Light Duty, 2- Paved, 3- Unimproved, 4- Other</p><p>2023: 1- Light Duty, 2- Paved, 3- Unimproved, 4- Other</p><p>2022: 1- Light Duty, 2- Paved, 3- Unimproved</p><p>2021: 1- Light Duty, 2- Paved, 3- Unimproved</p><p>2020: 1- Light Duty, 2- Paved, 3- Unimproved, 4- Other, 5- Decommissioned</p><p><strong>Spatial Resolution:</strong> 10m</p><p><strong>Source data:</strong> <a href="https://data.usgs.gov/datacatalog/data/USGS:ad3d631d-f51f-4b6a-91a3-e617d6a58b4e" rel="nofollow ugc noopener noreferrer" target="_blank"><u>USGS National Transportation Dataset</u></a></p><p><strong>Additional Resources:</strong></p><p>Details on <a href="https://usfs.box.com/s/79vx1b42xg8u6ivjombxjes36nzfhgml" rel="nofollow ugc noopener noreferrer" target="_blank"><u>Method Changes and Source Data Versions</u></a></p><p>Overview of the Terrestrial Condition Assessment: <a href="https://terrestrial-condition-assessment-usfs.hub.arcgis.com/" rel="nofollow ugc noopener noreferrer" target="_blank"><u>TCA Hubsite</u></a> or <a href="https://www.youtube.com/watch?v=Kf0P3cAq1rs&list=PLwRbAc4x5n94rLca1CXXuugtRDt_G666M&index=19" rel="nofollow ugc noopener noreferrer" target="_blank"><u>Landfire Office Hour Presentation</u></a></p><p>Explore the results of the most recent assessment: <a href="https://apps.fs.usda.gov/gtac-toolsms/tca/" rel="nofollow ugc noopener noreferrer" target="_blank"><u>TCA Interactive Data Viewer</u></a></p><p>Learn more about the TCA KPI: <a href="https://cxodashboard.dl.usda.gov/t/NRE/views/EcologicalConditionOutcomes_17531128629260/EcologicalOutcomes" rel="nofollow ugc noopener noreferrer" target="_blank"><u>TCA Dashboard</u></a></p><p>*if you have trouble viewing the Dashboard, please submit a <a href="https://usdagcc.sharepoint.com/sites/fs-wo-cdoc/SitePages/Dashboards.aspx" rel="nofollow ugc noopener noreferrer" target="_blank"><u>Tableau Viewer Access Request</u></a></p></div></div></div><div><br>This record was taken from the USDA Enterprise Data Inventory that feeds into the <a href="https://data.gov">https://data.gov</a> catalog.
