Easements — I7 Plates for Loir-and-Cher Underground Gas Storage

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）的覆盖范围即为其适用的空间场域（即地理区域）。该空间场域可采用二维或三维方式进行界定，在机场净空地役权、保护无线电发射中心的地役权等特定情形中尤为如此。
