The attitude of an easement is the spatial field (i.e., the geographical area) within which the easement applies. This space field can be defined either in 2D or in 3D in particular in the specific cases of airport clearance easements, easements to protect radio transmission centres.地役权（easement）的适用场域是其生效所覆盖的空间范围（即地理区域）。该空间范围可通过二维或三维方式予以界定，在机场净空地役权、保护无线电传输中心的地役权等特定情形中，此种界定方式尤为常见。
