# Field Boundary

## Introduction

**Field boundary definition:** A field boundary is a line which identifies the nature of the physical barrier feature and its characteristics when adjacent to, or contained within, specific types of land cover. Field Boundary features are predominately classified in rural and moorland areas of Great Britain. Vegetated Field Boundary features are given height and width values to give an indication of size. 

As both man-made (for example, a wall) and vegetated Field Boundary features (for example, a hedge) are regarded as structures, they are included in the [OS Structures Features Collection](/osngd/data-structure/structures/structure-features.md).
