How To: Create and Load a Multiple Channel Prescription
Overview: This document will explain how to create a multi-layered shape file with-in SMS software and then how to load it into an InSight
Three Prescription Maps need to be made and then loaded into the same map tab.
Follow These Steps:
When using the InSight to variable rate more than one product, a multi-layered Rx is needed to be able to load more than just one prescription. A single layer Rx will not work because the same layer cannot be loaded for two different products.
To start, once you get three prescriptions made, you will need to add each one of them to the same map. Once they are all being displayed on the current map you can right click in the map area and select export. After selecting export you will see a screen like the one shown in Figure 1.
This screen shows the export formats that are available for the current map. In the Data to Export box, the “Multiple Layers” option needs to be selected. For the “Export Format-Multiple Layers” box, you can select Insight Prescription or export as a Generic Shape File. Both formats have a similar process for exporting, but for this example we will use the Shape file format, as it allows for more flexibility when importing into an Insight.
Once the Export format has been chosen and you select “OK”, you will see the screen shown in Figure 2. Within the Layer Settings Box, you will first have to select the desired layer that you want to add to the Rx by selecting the drop down menu on the Select Layer option. Once you have selected the Layer you want to add, observe the Export Units and Default rate selections and change if needed. After those values have been set up correctly you can select “Add>>” from the center of the window to include it in the “Selected Export Layers.” Follow this procedure for the other two Rx Layers and then click “OK.”
After Selecting “OK” SMS will generate a preview of what the prescription will look like as individual layers where you can view the map and legend of each Rx as shown in Figure 3.
After Selecting OK on the Export Preview window it will ask where you want to save the file to. It is recommended to first save the shape file to your hard drive, and then transfer it to the card. The shape file consists of three individual file parts that must be kept together, so when moving the files from your computer to a card make sure to transfer the shp, dbf, and shx files.
Multiple Channel Rx on the InSight
Once a configuration has been loaded with the correct number of products being applied and in the correct units, you can load the Rx file.
First you will go to the Map tab at the bottom of the Run Screen. From there you will see a Load Rx button that will be pressed as in Figure 4. A file selection window Figure 5 appears from which you will select the desired shape or IRX file from. Although the Shape file consists of three parts, you will only see the SHP part of it. Once you’ve highlighted the file, press Accept. A SHP to IRX Conversion Wizard will appear, touch Next. The next step is to select the number of products you want to variable rate. With a SHP file you can select to only variable rate one product even if the file contains the information to VR 3 products, an IRX file requires you to assign each layer to a product. Once you selected the number of products (in this example there are three) Figure 6 press Next.
At this point we begin assigning equipment/channels to each layer of the SHP file. Step 1 of 4 Figure 7 you will select the Channel (for multiple channel modules like the Strip-Till or Stepper Seed Rate module) or equipment configuration to assign first press Next. Step 2 of 4 Figure 8 allows you to tell the InSight what product is associated with Channel 1 and the units it needs to be applied in, this should be selected to match the information the Rx was made for, press next. Step 3 of 4 Figure 9 allows you to select the column of the SHP file that will be used as target rate values for the product that was selected in step 2, it will show a preview of the values assigned to that column on the right. This is a way to verify that the correct column and rates are being selected. Step 4 of 4 Figure 10 gives you the ability to set a default rate to apply if the SHP file does not cover the entire field or if you wish for it to apply outside the field boundary, press next. Now we will be back to selecting the Shapefile to use for Product 2 and the process will be the same as above.
