Collecting, interpreting, and using GPS/GIS data

1. Collecting, interpreting, and using GPS/GIS data Jay Solomon Engineering Technology East Peoria Center

2. Field maps setbacks Setbacks on Field Maps Well setback 80 acres 1/4 mile broadcast setback Residence stream

4. Focus • Moving past the concept into adoption • Boundary / setback maps • Field systems • Uses of the technology and data

5. Terms • GPS – Global Positioning System • GIS – Geographical Information System

6. Background maps • Field boundaries • Setbacks • Application areas • Variable rate application (VRA) • Soil sample based areas • Soil types

7. Types of maps • Graphics - Pictures • Printed • Electronic • Geo-referenced electronic files • Single file • Multiple files with the same name- different extensions

8. How to get boundary/setback maps • Manure plan consultant

10. How to get boundary/setback maps • Manure plan consultant • Self developed • RMMS web site • Commercial crop production software • GIS software

11. Buffers of injected application

12. Application maps Soil type

13. P Application Maintenance plus Buildup P Soil Test

14. Useful information • Application acreage – (not field acreage) • Acreage of setbacks, waterways • Graphic information for decision making • Direction application • Equipment layout • especially towed hose or nurse tank system

15. Field Application:The Human System Speed v. rate chart

16. What could a field system do? • Preload buffer and boundary maps • Show current location • As- applied mapping • Variable rate application • Automatic • Facilitate operator controlled VRA

17. In Field Systems • IPAQ based • Raven Controller/ Monitor • AgLeader Controller/Monitor • Outback Monitor/Controller

18. Useful information From field equipment • Application acreage – Actual area applied • Total fluid applied • Variation in application across the field • Missed areas • Start and stop locations • Observation of setbacks

19. Application Track

20. As-Applied Map

21. GIS Layers

22. Uses of the technology and data • Calibration • Maps for manure plan • Application plan (uniform or variable) • Application record • Record of start and stop locations • Crop fertility layer

23. Calibration • GPS distance can be used for initial calibration • Total acreage applied • Record of loads or total flow volume

24. Calibration • With flow meter and GPS receiver • Record total flow (TF) • Record distance (DS) • Application width (AW) Application rate = 43560 x TF DS x AW

25. Calibration check • Calculate volume from storage (SV) • Calculate total acreage (TA) • From date or with GPS receiver Ap. rate (storage) (ARs) = SV TA

26. Calibration check • Calculate total acreage (TA) • From date or with GPS receiver • Total from the flow meter (TF) Ap. Rate (flow meter) (ARf)= TF TA

27. Calibration check • Does (ARs) = (ARf) • How different are they? • Which is more accurate? • What could be the difference?

28. As- applied maps • Print copy of as-applied on file • Electronic copy • Provide to crop producers, fertilizer consultants

29. Electronic files • Illinois Manure Management Plan tool • www.immp.uiuc.edu • Can upload picture format files • .jpg, .tif, .gif, .pdf • Working on other file extension compatibilities (.shp, etc.)
