2 Contents What is GAOS? Workflow Tool Results Future of GAOS

3 What is GAOS? In Dutch: Geo Akker Optimalisatie Service Geo Arable field Optimisation Service Support for GPS guided steering Planning in advance Allocate areas of inefficient machine manoeuvring to field margins Optimise tracks Explore planning alternatives

4 Effects field margins & planning tracks Agri-environmental landscape Biodiversity Operational benefits Physical soil properties (permanent tracks) Plant protection Down side Permanent source of weeds Area loss weigh area loss against efficiency gain

5 Basic idea: optimise base pattern

6 Work / data flow (global)

7 RTK-GPS data acquisition ( surveyor )

8 Specification of optimisation

9 RTK-GPS Terminal & auto-steering

10 Tool: layered architecture Data entry application: LuigiOS Flex client Map service: OGC WMS (GeoServer, ArcGIS Server) Feature service: OGC WFS-T (GeoServer) Processing service: OGC WPS (PyWPS) Scripts: Python, OGR PostgreSQL/PostGIS database for dedicated data model

11 Functionality of data entry web application Visualisation of data (parcels, edges, optimisation results) Editing of edges (split and merge edges) Definition of optimisation parameters Add headlands Sprayer on/off reference line Edit reference lines Add/remove/change points Make curved connections Generate output work line

13 Optimisation get input script data compute set of angles compute set of positional shifts for each angle: for each shift: compute a parallel swath pattern for each potential field margin: if condition: else: compute areas delete swaths overlapping margin cut swaths at intersection cost = sum partial costs retain design with lowest cost apply changes: add headlands, edits generate output data

14 Output for auto steering systems

15 Optimisation result

16 Support for 2 brands, 4 export formats Spatial analysis - local

17 Visible planning patterns

19 Application of GAOS in the Hoeksche Waard Number of farmers 2010 ~ ~ ~ en

20 Future of GAOS Extend user group Continue operation (Funding?) Extend functionality Choose between optimal and sub optimal Add reporting e.g. for loss and gain Visualise field margins within extent during planning

21 Future of GAOS: CAP Position for CAP Ecological Focus Area (EFA): parcel planning system can provide meaningful support Adapt for CAP (greening) Knowledge rules: 5% of area designated as Ecological Focus Area (EFA s) Collectives support Reporting: Totals of different area types per farmer and collective

22 Example parcel: 5% green

25 GI requirements for agro-environmental management

26 Feedback from application in Hoeksche Waard Plan in advance (winter) Simple fields OK Full width spray paths Headlands and complex field shapes Spray paths, sections closed Curves Export functionality (1x) Weeds

27 Agricultural vehicle Work / data flow (global) Farmer/ FMS Surveyor Support Request survey Field geometry RTK GPS survey Check AB-line on USB memory stick Geometry, specifications and wishes Optimisation results Additional constraints Final optimisation results Optimisation Adjustment
