{ "currentVersion": 11.3, "cimVersion": "3.3.0", "id": 1057, "name": "Trees Outside Woodland (TOW)", "type": "Feature Layer", "description": "The National Trees Outside Woodland (TOW) V1 map is a vector product funded by DEFRA\u2019s Natural Capital and Ecosystem Assessment (NCEA) programme produced under Forest Research\u2019s Earth Observation for Trees and Woodlands (EOTW) project.\n\nThe TOW map identifies canopy cover over 3m tall and 5m2 area which exists outside the National Forest Inventory (National Forest Inventory - Forest Research). Canopy cover is categorised into the following woodland types - lone trees, groups of trees and small woodlands.\n\nThe data set was derived from the Vegetation Object Model (VOM) (Environment Agency, EA), the National Lidar Survey (EA), and Sentinel-2 (European Space Agency) imagery using spatial algorithms. The method is fully automated with no manual manipulation or editing. The map and its production method has been quality assured by DEFRA science assurance protocols and assessed for accuracy using ground truth data.\n\nBecause the process classifies objects based on proximity to features within OS mapping, there could be some misclassifications of those objects not included in the OS (specifically: static caravans, shipping containers, large tents, marquees, coastal cliffs and solar farms).\n\nThis is a first release of this dataset, the quality of the production methods will be reviewed over the next year, and improvements will be made where possible.\n\nThe TOW map is available under open government licence and free to download from the Forestry Commission open data download website (Forestry Commission) and view online on the NCEA ArcGIS Online web portal (Trees Outside Woodland). A full report containing details on methodology, accuracy and user guide is available.\n\nTOW map web portal link : ncea.maps.arcgis.com/apps/instant/sidebar/index.html?appid=cf571f455b444e588aa94bbd22021cd3\n\nFR TOW map web page : https://www.forestresearch.gov.uk/tools-and-resources/fthr/trees-outside-woodland-map/", "geometryType": "esriGeometryPolygon", "sourceSpatialReference": { "wkid": 27700, "latestWkid": 27700, "xyTolerance": 0.001, "zTolerance": 0.001, "mTolerance": 0.001, "falseX": -5220400, "falseY": -15524400, "xyUnits": 10000, "falseZ": 0, "zUnits": 1, "falseM": 0, "mUnits": 1 }, "copyrightText": "© Forestry Commission copyright and/or database right 2025.
