1 1 GNSS as a key instrument for administration and control of CAP direct aids Wim Devos MARS Unit - JRC Ispra

2 CAP in the simpliest words: 2 Pillar 1: Direct Aid to farmer (40 bn /2010) decoupled from the production: a farmer receives aid for area eligible: i.e. land with crop, grass or if out of production- kept in good condition subject to cross-compliance: i.e. conditional to respecting EU requirements on environment & public, animal and plant health (e.g. animal welfare, soil protection, minimum level of maintenance ) Every year: 1. farmer declares (locates + quantifies area) his land by LPIS 2. all claims are administratively crosschecked with LPIS 3. >5% of the farmer claims are on the spot checked 4. area determined is paid to farmer - managed by an Integrated Administration and Control System Pillar 2: Rural development (14 bn /2010) other, including CMO ( 4 bn /2010)

4 Methodologies: RS + GNSS Legal Framework 2009R73 art. 20 Member States may use remote sensing and Global Navigation Satellite System (GNSS) techniques as a means of carrying out on-the-spot checks on agricultural parcels 2009R1122 art 33: Member States may make use of remote sensing in accordance with Article 35 and Global Navigation Satellite Systems techniques where possible Regulatory specifications (since 2004): LPIS : shall be established on the basis of maps or land registry documents or other cartographic references. Use shall be made of computerized geographical information system techniques, including preferably aerial or spatial orthoimagery, with a homogenous standard guaranteeing accuracy at least equivalent to cartography at a scale of 1: m RMSE, 1m LMA OTSC/CwRS area: 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. 4

7 LPIS orthoimagery 7 Occurrence of GSD Based on a short websurvey: 11/27 MS replied Use of orthoimagery with certain resolution in EU Member States for the purpose of LPIS 100% 80% Use in percent 60% 40% 20% 0.10 m 0.25 m 0.5 m 1 m 2 m 0% earlier than later than 2011 Year

9 9 OTSC trends

10 classical OTSC area measurement 10 Key numbers 8M claims in 2009 >600,000 claims (12M ha) checked OTS 220,000 checked with classical inspection (mainly GPS) estimated number of GNSS area measurements: /yr rest (380,000 or 60% of OTSC) checked using RS, but part of these need follow up inspections in the field with GNSS (so-called Rapid Field Visit) About 2000 permanent inspectors (+ temporary staff) ~ devices

11 Evolution of tolerance in Regulation 11 A tolerance shall be set f( measuring method, official documents, accuracy, local factors (parcel slope, shape)) Tolerance 5% parcel area or 1.5m buffer x perimeter Max 1 ha idem, but for parcels < 0.1ha Tolerance 1.5m buffer Tolerance = f(device) Max 1.5m buffer R92 118R R05 972R R01 796R04 amending 1122R09 Main Commission regulation in blue Reg changing tolerance in red

12 GNSS use for CwRS All devices should be validated: Area measurement performance should be determined through validation tests or certification (buffer =< 1.5m) 12 certification ppp validation Member_States present results (buffer width): 1 model <1.25m, 3 models <1m, 10 models <0.75m 9 models (mostly with differential correction) < 0.5m

13 VHR satellite data in CwRS -OTSC EU 15 EU 25 EU 27 Prime sensors IK, QB GE1 IK, QB GE1, WV2 13 area of VHR zones (km2) IK, QB planned VHR area acquired VHR area Test : Ikonos (1m) 2000 Eros A (2.5m, P) 2001: QBird (0.6m) cam paign Eros B (0.8m, P) WV1 (0.5m, P) GE1 (0.5m) WV2 (0.5m)

14 Conclusions CAP-IACS is the largest pan-eu spatial application set-up by the EC ( ), including GIS, orthoimagery and GNSS use. 2. CAP systems (IACS) require much better accuracies than Regulations explicit: LPIS operational scales are 1/2000 to 1/5000 OTSC buffer tolerances for GNSS around 0.5 to 1m CwRS imagery trend is towards 50 cm GSD 3. Strong (financial drive) to ever higher accuracies

15 GNSS Needs / Challenges 15 Both control mechanisms (LPIS and OTSC) are developing towards a 50 cm positional accuracy Available solutions have disadvantages Service based (RTK and other dgps) Require complicated procedures. What is hindering a stand alone solution? No appropriate service available G@lileo? No off-the shelf devices available. What if the 8 M EU farmers could use GNSS directly for their aid application?
