The data capture using temporary adjudication is illustrated in figure 2. This example describes a situation where SUT has 2 reference parcels that contain agricultural area (RP1 and RP2) and two LF that hold eligible hectares. Note that the features visible in Figure 2 will be delineated during the ETS inspection and will later be reported in the etsObservations.gml.

Since LF1 and LF2 contain no agricultural area, but represent eligible hectares; thus they have to be temporarily adjudicated to either RP1 or RP2 for the duration of the quality assessment.

  • LF1 is engulfed by RP1, and totally adjudicated to RP1
  • LF2 has 310m of shared border with RP2 and only 150m with RP1 so it is totally adjudicated to RP2Figure 3 shows the result of this adjudication and the resulting lpisPointZeroState values, note that only two point coordinates (+) are delivered for the original 4 SUT entities and that the etsReferenceArea for LPIS QA reference parcel is the sum of all contributing areas.

Full lines of figure 4 show the resulting ETS LUI and the polygons included in the lpisPolygonZeroState.gml. Hashed lines represent original SUT polygons.
