What is LUCAS? Methodology Results Conclusions
What is LUCAS?
• An area frame survey:
Statistical method based on the visual observation of sampled geo-referenced points to compute area estimates
• Objectives
•To obtain harmonised data at EU25 level on:– Land use and Land cover– Environmental features
•To provide a common methodology-nomenclature ensuring full comparability of results•To calculate early estimates of areas (main crops) in June/July•To analyse the interaction agriculture-environment-landscape (multi-purpose survey)
What is LUCAS? - Calendar of activities
• 2001 - survey carried out in 13 MS
• 2002 - survey carried out in UK and IE and in EE-HU-SI
• 2003 - survey carried out in 15 MS + Hungary
• 2005 - survey carried out in LT-LV-PL
• 2006 - survey carried out in 11 MS
• + PHARE Multi-Country 2000 and 2003 Programmes on Sectoral Pilot Projects in Agriculture and Environment Statistics

Methodology: Sampling Design Base sample:
- Uniform square grid of 1km side length over the entire territory of the EU Member States:
- ETRS89 Lambert Azimuthal Equal Area coordinate reference system (ETRS-LAEA):
» Centre point: 52°North 10° East» Origin: 4.321.000 meters west, 3.210.000 meters south of centre point
- 4.025.583 nodes = base sample points Master sample (even points of the base sample):
- 2km grid: about 1 Mio sample points Photo-interpretation of all master sample points into 7 strata:

What is LUCAS? Methodology Results Conclusions
Conclusions
LUCAS is not covering all countries Sampling focused on agricultural area but also covering all strata Stratification available Around 1.000.000 photos taken. Photos have to be checked and
“anonymised” before transmission Follow-up evaluation of landscape classification, Grid data
combination, comparison with other surveys, further use of LUCAS data, technological watch. Call for tender for “erosion risk” features
Photo-interpretation is not an easy process without ground information (confusion matrix) …
Further conclusion … nor is it observing on the ground!
