4. Technical Realisation
The yearly budget for the Common AgriculturalPolicy (CAP) in Europe is around 55 billion Euro’s
1. Introduction: Setting the scene
Source: http://ec.europa.eu/agriculture/capexplained/cost/i ndex_en.htm
The bulk of this money goes to
farmers in Europe
subsidies
The amount of subsidies a farmer recieves is closelylinked to the agricultural land he uses/cultivates
1. Introduction: Setting the scene
==
For example: In the Netherlands and Belgium on average a farmer receives around € 460 per hectare 1

1. Introduction: Setting the scene
Member States have to take the necessary measures to assure t hat
transactions financed by the European Agricultural Guaran tee Fund
are actually carried out and executed correctly, and to prev ent and
deal with irregularities.
In order to check the declared area an identificati on system
covering all agricultural areas called Land Parcel Identification
System (LPIS) needs to be set up!

Purpose of the Land Parcel Identification System
� Goal: identification of each agricultural parcel declared by farmers� Obtained: through “reference parcels” providing

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

RELATED TO LPIS/GIS
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
TO SETUP AN LPIS

HOW TO MAINTAIN AN LPIS

TO SETUP AN LPIS HOW TO MAINTAIN AN LPIS
2. Overview: LPIS QAF
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.
2 PRIME FUNCTIONS FOR ANY LPIS
(cover) within.
How do we test this?
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’
2. Overview: LPIS QAF
LANDSCAPE CHANGES AND OPERATORS MAKE ERRORS
NO PROBLEM
NATURE or AGRICULTURE? ROADWORKS
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
4. Realisation: ETS Tool
SETUP (1)
Running the Setup Wizard Setting Up the INI-file
4. Realisation: ETS Tool
SETUP (2)
(Normal User Toolbar)
(Super User Toolbar)
4. Realisation: ETS Tool
Super User functionality allows
you to manage the workload
- Number of Sets
- Size of the Sets
4. Realisation: ETS Tool
Super User functionality
also offers management information
4. Realisation: ETS Tool
Checking the Sample (normal user)
1. Start checking
- An ID is assigned to the user
- 3 shapefiles are loaded- 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
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
4. Realisation: ETS Tool
CREATING NEW POLYGONS
MODIFYING EXISTING POLYGONS
CUTTING EXISTING POLYGONS
The tool uses standard ArcGIS edit-functionality
4. Realisation: ETS Tool
THE TOOL AUTOMATICALLY CALCULATES THE
DIFFERENCE BETWEEN THE OLD AND NEW POLYGON

5. Future developments
1. Improving the reporting facility
2. Bringing the tool online2. Bringing the tool online
3. Focussing more on the results
