To create a zonation map, add prescription values, and export a zonation map as a shapefile, click here.

Export a zonation map as shapefile for a terminal tractor:

  1. Create a zonation map from an index map. 
  2. Input prescription values on the zonation map.
  3. Export the zonation map as a shapefile. (In some cases, you might need to convert the shapefile to a compatible file format of your terminal).
  4. Click Export as individual files. (Most terminals require unzipped shapefiles).
  5. Save the shapefiles onto a USB Drive. 




Note:  PIX4Dfields supports tractor terminals that are able to import a zonation & prescription map from a shapefileFor more information about the supported formats of your tractor, please refer to your precision display manual or consult with your precision equipment technician.

How is the shapefile organized?

  1. The attribute table of the exported shapefile has four columns: amount, area_ha, avg Value, and rate_ha.
  • amount: quantity of rate needed for each zone. This value is calculated automatically.
  • area_ha (ac): area in ha or ac of each zone.
  • avgValue: average index value on each zone.
  • rate_ha (ac): this value is added manually when generating the prescription tool.
Note:  Units are not recorded in the table, please keep a record in order to use proper rates.

2. The number of rows corresponds to the number of zones, which can vary from 2 to 7.


The following table is an example of the attribute table that you will get with PIX4Dfields:

amount area (ha/ac) avgValue rate (ha/ac)
Note:  Please check with the terminal manufacturer regarding shapefile restrictions (For example, number of polygons).

What is the difference between exporting a shapefile as a zip file and as individual files?

Using PIX4Dfields, a shapefile can be exported in two different ways: as a zip file, or as individual files.

A shapefile exported as a zip file contains multiple files (.dbf, .prj, .shp, and .shx) that have been compressed. Most tractor terminals (displays) use individual shapefiles exported to a specific folder on the terminal. Therefore we recommend exporting the shapefile as individual files.

Import zonation & prescription map to a tractor terminal (display)

Export a zonation map as shapefile for a terminal tractor:

  1. Import the shapefiles into the desired tractor terminal. 
  2. Select rate_ha (ac).
  3. Select the units. 
  4. Okay.
Note:  The import steps may vary depending on the terminal. The most common procedure is described above. Check some examples: Ag Leader Integra Prescription Import Kansas and John Deere GS 3 2630 Prescription Upload 2016

How to change the zonation & prescription map units from ha to ac or vice-versa?

Click here for more information about the dashboard 

  1. Go to the dashboard SETTINGS.
  2. Change from Imperial units to Metric or vice-versa. 
  3. Export the zonation as shapefile again.
Note:  The coordinate system of the shapefile is the corresponding Universal Transverse Mercator (UTM) zone (datum WGS84).
