Terrestrial Condition Assessment (TCA) Road Density

<div style='text-align:Left;'><div><div><p><a target='_blank' href='https://data.fs.usda.gov/geodata/rastergateway/TCA/TCA_Road_Density.zip' rel='nofollow ugc noopener noreferrer'><span><strong><u>Direct Download (Raster Data Gateway)</u></strong></span></a></p><p><span><strong>Objective:</strong> Identify locations where roads are present at a density that impacts the quality of wildlife habitat and fragments the landscape.</span></p><p><span><strong>Data:</strong> 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:</span></p><ol><li><span>Unimproved: Four-wheel drive roads.</span></li><li><span>Paved: Controlled access highway, Secondary Highway or Major Connecting Road, Ramps</span></li><li><span>Light Duty: Local Connecting Roads, Local Roads</span></li></ol><p><span><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:</span></p><p><span>2024: 1- Light Duty, 2- Paved, 3- Unimproved, 4- Other</span></p><p><span>2023: 1- Light Duty, 2- Paved, 3- Unimproved, 4- Other</span></p><p><span>2022: 1- Light Duty, 2- Paved, 3- Unimproved</span></p><p><span>2021: 1- Light Duty, 2- Paved, 3- Unimproved</span></p><p><span>2020: 1- Light Duty, 2- Paved, 3- Unimproved, 4- Other, 5- Decommissioned</span></p><p><span><strong>Spatial Resolution:</strong> 10m</span></p><p><span><strong>Source data:</strong> </span><a target='_blank' href='https://data.usgs.gov/datacatalog/data/USGS:ad3d631d-f51f-4b6a-91a3-e617d6a58b4e' rel='nofollow ugc noopener noreferrer'><span><u>USGS National Transportation Dataset</u></span></a></p><p><span><strong>Additional Resources:</strong></span></p><p><span>Details on </span><a target='_blank' href='https://usfs.box.com/s/79vx1b42xg8u6ivjombxjes36nzfhgml' rel='nofollow ugc noopener noreferrer'><span><u>Method Changes and Source Data Versions</u></span></a></p><p><span>Overview of the Terrestrial Condition Assessment: </span><a target='_blank' href='https://terrestrial-condition-assessment-usfs.hub.arcgis.com/' rel='nofollow ugc noopener noreferrer'><span><u>TCA Hubsite</u></span></a><span> or </span><a target='_blank' href='https://www.youtube.com/watch?v=Kf0P3cAq1rs&amp;list=PLwRbAc4x5n94rLca1CXXuugtRDt_G666M&amp;index=19' rel='nofollow ugc noopener noreferrer'><span><u>Landfire Office Hour Presentation</u></span></a></p><p><span>Explore the results of the most recent assessment: </span><a target='_blank' href='https://apps.fs.usda.gov/gtac-toolsms/tca/' rel='nofollow ugc noopener noreferrer'><span><u>TCA Interactive Data Viewer</u></span></a></p><p><span>Learn more about the TCA KPI: </span><a target='_blank' href='https://cxodashboard.dl.usda.gov/t/NRE/views/EcologicalConditionOutcomes_17531128629260/EcologicalOutcomes' rel='nofollow ugc noopener noreferrer'><span><u>TCA Dashboard</u></span></a></p><p><span style='font-family:&quot;Aptos&quot;,sans-serif; font-size:12.0pt;'><span style='line-height:115%;'>*if you have trouble viewing the Dashboard, please submit a </span></span><a target='_blank' href='https://usdagcc.sharepoint.com/sites/fs-wo-cdoc/SitePages/Dashboards.aspx' rel='nofollow ugc noopener noreferrer'><span style='font-family:&quot;Aptos&quot;,sans-serif; font-size:12.0pt;'><span style='line-height:115%;'><u>Tableau Viewer Access Request</u></span></span></a></p></div></div></div>
