Create and Export Management Zones and Prescription Files

Now available for satellite imagery!

Management zones are used to group the data of a detailed health map into simple shapes that can then be exported as a prescription file. Below is an example of a zone map (left) and the health map which was used to create the management zone. ​

Management Zones on Web

  1. Open FieldAgent.Sentera.com and navigate to the field you'd like to create a zone map for.

  2. Open the map layer you'd like to create the zone map from. Note: RGB layers cannot be turned into zone maps.

Some types of map layers that can be turned into zone maps include:

  • NDVI or NDRE Satellite Imagery

  • NDVI or NDRE QuickTiles or Mosaics

  • Populations Maps (from a Stand Count)

  • Tassel Maps (from a Tassel Count)

  1. Set the mosaic display mode to Zone map

  2. Manipulate the layer as you'd like:

    • Select the number of bins (colors)

    • Set the minimum and maximum values to be included

  3. Click Download Shapefile

The downloaded file can now be used in a tool such as SMS to create a prescription.

Management Zones on Desktop

To create management zones and subsequent prescription file:

  1. Open FieldAgent on your Desktop.

  2. Navigate to the field you’d like to create a prescription for.

  3. Select the layer you’d like to create a prescription from.

  4. Select the Toolbox.

  5. Select the Gears icon.

  6. A popup window will indicate loading status. Note that this process may take some time.

  1. A prescription can then be created. Re-open the toolbox and select the RX icon.

  2. Set the units and rate at which the file should be written for.

Area Isolation Example

To write a prescription for only the worst or best areas of a field use the toolbox to manipulate the dataset before running the management zone tool. Isolate a specific part of the field by setting the bins to 1 and then drag the min and max sliders around on the graph.

Settings for this example:

  1. Bins were set to 1

  2. Color Map set to Reds

  3. Max slider moved to the left

  4. Generate a management zone by pressing the gear icon in the toolbox

In this case, the worst performing areas of the field were isolated for treatment.
