4. Technical Realisation

The yearly budget for the Common AgriculturalPolicy (CAP) in Europe is around 55 billion Euro’s

1. Introduction: Setting the scene

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

has set up their own LPIS

or even

THE WORLD?More than 50 LPIS systems!

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

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
