Directive1122/2009
Article 45
Detailed rules regarding the determination of areas and the measuremetn
methods to be used should be laid down to assure a quality of the
measurement which is equivalent to that required by technical standards
as drawn up at Community level.
Technical standard as defined by JRC:
A measurement tolerance shall be defined by a buffer of
maximum 1.5 m applied to the perimeter of the agricultural
parcel. The maximum tolerance with regard to each
agricultural parcel shall not in absolute terms, exceed 1,0 ha.
