Collecting, interpreting, and using GPS/GIS data Jay Solomon Engineering Technology East Peoria Center
Field maps setbacks Setbacks on Field Maps Well setback 80 acres 1/4 mile broadcast setback Residence stream
Focus • Moving past the concept into adoption • Boundary / setback maps • Field systems • Uses of the technology and data
Terms • GPS – Global Positioning System • GIS – Geographical Information System
Background maps • Field boundaries • Setbacks • Application areas • Variable rate application (VRA) • Soil sample based areas • Soil types
Types of maps • Graphics - Pictures • Printed • Electronic • Geo-referenced electronic files • Single file • Multiple files with the same name- different extensions
How to get boundary/setback maps • Manure plan consultant
How to get boundary/setback maps • Manure plan consultant • Self developed • RMMS web site • Commercial crop production software • GIS software
Application maps Soil type
P Application Maintenance plus Buildup P Soil Test
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
Field Application:The Human System Speed v. rate chart
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
In Field Systems • IPAQ based • Raven Controller/ Monitor • AgLeader Controller/Monitor • Outback Monitor/Controller
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
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
Calibration • GPS distance can be used for initial calibration • Total acreage applied • Record of loads or total flow volume
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
Calibration check • Calculate volume from storage (SV) • Calculate total acreage (TA) • From date or with GPS receiver Ap. rate (storage) (ARs) = SV TA
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
Calibration check • Does (ARs) = (ARf) • How different are they? • Which is more accurate? • What could be the difference?
As- applied maps • Print copy of as-applied on file • Electronic copy • Provide to crop producers, fertilizer consultants
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.)
