Introduction

This page contains some examples of different scenarios for the reporting of the etsReferenceArea and the corresponding agricultural land cover categories in the LpisPointZeroState, depending on the specific LPIS implementations adopted by the EU MS. The examples are collection of the RPs from real cases taken from the annual ETS reports (except for some area values).

Example 1 - Basic

Reference parcel in the picture 1. below is a physical block with graphical RP area of 2,8141 ha. Reference parcel polygon contains 4 agricultural parcels each classified as arable land. Ineligible part inside the block is excluded from the RP polygon and RP area. In such case a LpisPointZeroState.gml record should have following attributes:

LpisPointZeroState Ha
etsReferenceArea 2,8141
arableLandArea 2,8141
permanentCropArea 0
permanentGrasslandArea 0

(Note: other attributes are left on purpose)

Example 2 - Grassland with pro-rata coefficient

Reference parcel in the picture 2. below is a parcel with graphical RP area of 6,6797 ha. It is classified as a mix of grass and ineligible vegetation, hence graphical area should be reduced. Pro-rata category for this grassland was observed to be Grassland80 and eligibility rate of 80% was used for area reduction (sporadic assesment). In such case a LpisPointZeroState.gml record should have following attributes:

LpisPointZeroState Ha
etsReferenceArea 5,3438
arableLandArea 0
permanentCropArea 0
permanentGrasslandArea 5,3438

(Note: other attributes are left on purpose)

Example 3 - RP with multiple LC classes

Reference parcel in the picture 3. below is a physical block with graphical RP area of 3,7218 ha. Reference parcel contains 7 agricultural parcels: 2 parcels classified as arable land (0,1856+0,3923 ha), 3 parcels classified as permanent crop (0,8874+0,1137+0,0585 ha) and 2 parcels classified as permanent grassland (1,2596+0,4726 ha). Note that RP boundary is not following the physical limits of the landuse as visible on the orthophoto image. We assume that the ineligible vegetation, located along the RP boundary, has penetrated inside the RP over the years. Still, all agricultural parcels within the RP have been updated in the system with available agriculture areas so the sum of all three LC categories equals the available land (can be also equal to MEA). In such case a LpisPointZeroState.gml record should have following attributes:

LpisPointZeroState Ha
etsReferenceArea 3,3697
arableLandArea 0,5779
permanentCropArea 1,0596
permanentGrasslandArea 1,7322

(Note: other attributes are left on purpose)

Example 4 - RP with landscape features

This specific case is from a system containing landscape features as individual reference parcels. For the purpose of the ETS quality assessment a data manipulation should be conducted in order to spatially join the landscape features and correspondent reference parcel. In the picture 4. below is the reference parcel polygon bounding 8 smaller polygons of landscape features. So each polygon is a single spatial unit. Note that one LF with a red point is considered being out of ETS scope by the EU Member State (possibly a landscape feature recorded as EFA, but not subject to retention (GAEC 7); thus not considered as eligible for BPS/SAPS).

Since ETS scope cannot have LFs as individual polygon with an unique RP identifier, all LF polygons in scope should be merged with RP like in the picture 5 below.

Finally, this reference parcel is represented as single RP polygon where the available RP area does per category not sum up the LF areas. The area of the landscape features allotted (or adjudicated as specified in the Annex IX) to the RP during the preparation of the LPIS population is accounted and added to the etsReferenceArea for the purpose of the ETS, but it might not be reflected in the area per agriculture category if the latter is stored in the corresponded attribute fields in the LPIS. In such case a LpisPointZeroState.gml record should have following attributes:

LpisPointZeroState Ha
etsReferenceArea 18,4507
arableLandArea 0
permanentCropArea 0
permanentGrasslandArea (does not include the area of adjudicated LFs) 18,1350

(other attributes are left on purpose)


The last picture 6. below is labelling graphical areas of each polygon within the LUI in subject.
