3. 1. Introduction: Setting the scene
The yearly budget for the Common Agricultural
Policy (CAP) in Europe is around 55 billion Euro’s
The bulk of this
money goes to
farmers in Europe
subsidies

4. 1. Introduction: Setting the scene
The amount of subsidies a farmer recieves is closely
linked to the agricultural land he uses/cultivates
=
For example: In the Netherlands and Belgium on
average a farmer receives around € 460 per hectare 1

6. 1. Introduction: Setting the scene
Member States have to take the necessary measures to assure that
transactions financed by the European Agricultural Guarantee Fund
are actually carried out and executed correctly, and to prevent and
deal with irregularities.
In order to check the declared area an identification system
covering all agricultural areas called Land Parcel Identification
System (LPIS) needs to be set up!
8. 1. Introduction: Setting the scene
Purpose of the
Land Parcel Identification System
Goal: identification of each agricultural parcel declared by farmers
Obtained: through “reference parcels” providing
A geographic location
LPIS
Identification of parcel extent, boundaries
A reference area
Other elements of eligibility

10. 1. Introduction: Setting the scene
Each European Member State
has set up their own LPIS
BIGGEST GIS
IN EUROPE
or even
More than 50 LPIS systems!
THE WORLD?
Millions of objects!
12. 1. Introduction: Setting the scene
What happens if you do not comply with regulations?
Financial corrections!

13. 1. Introduction: Setting the scene
In relation to the LPIS/GIS Member States have asked for
further clarification on which elements are important
GUIDELINES HOW NO GUIDELINES
TO SETUP AN LPIS HOW TO MAINTAIN AN LPIS
LPIS Quality Assurance Framework
(Art. 6 of Commission Regulation (EC) 1122/2009)
14. 2. Overview: LPIS QAF
2 PRIME FUNCTIONS FOR ANY LPIS
1. a stable identification of the land use - the basis
for aid application in any scheme –
2. the correct quantification of the agriculture land
(cover) within.
How do we test this?
15. 2. Overview: LPIS QAF
Do we test the entire reference dataset?
Sample size is based
on ISO 2859/2-1985
(Procedure A, Limiting Quality = 2%)
NO! We take a sample.
ISO also describes what is
‘acceptable’ and what is
‘not acceptatble’
16. 2. Overview: LPIS QAF
LANDSCAPE CHANGES AND OPERATORS MAKE ERRORS
NO PROBLEM
NATURE or AGRICULTURE? ROADWORKS
17. 3. Problem space: What is needed?
Workflow related to the
LPIS QAF is fairly complex
(Generic )Tool that
- provides management information
- is easily adjustable
- supports the workflow
- allows for multi-user use
- uses standard (ArcGIS) edit functionality
ArcGIS Extension
(within ArcGIS 9.3.1) VB.NET
18. 4. Realisation: ETS Tool
SETUP (1)
Running the Setup Wizard Setting Up the INI-file
19. 4. Realisation: ETS Tool
SETUP (2)
(Normal User Toolbar)
(Super User Toolbar)
20. 4. Realisation: ETS Tool
Super User functionality allows
you to manage the workload
- Number of Sets
- Size of the Sets
21. 4. Realisation: ETS Tool
Super User functionality
also offers management information
22. 4. Realisation: ETS Tool
Checking the Sample (normal user)
1. Start checking
- An ID is assigned to the user
- 3 shapefiles are loaded
• a polygon shape with control parcels
• a polygon shape for observed parcels
• a point shape for remark-points
Information for the user
23. 4. Realisation: ETS Tool
Checking the Sample
The tool zooms to the first
Shape that hasn’t been
checked
Next step is redigitising
the polygon based on
recent orthoimagery
using standard ArcGIS
edit-functionality
24. 4. Realisation: ETS Tool
The tool uses standard ArcGIS edit-functionality
CREATING NEW POLYGONS
MODIFYING EXISTING POLYGONS
CUTTING EXISTING POLYGONS
25. 4. Realisation: ETS Tool

THE TOOL AUTOMATICALLY CALCULATES THE
DIFFERENCE BETWEEN THE OLD AND NEW POLYGON

29. 5. Future developments
1. Improving the reporting facility
2. Bringing the tool online
3. Focussing more on the results
