Importing TerrAvion GeoTIFF and creating VRA Maps in SMS
In this article, we will go over how to import your TerrAvion data into Agleader’s SMS to create Variable Rate Application maps.
This article is divided into two sections: First, we explain how to import TerrAvion geoTIFFs into SMS. Next, we will create a Variable Rate Application Map within SMS.
File Import and Integration
After you login into the TerrAvion Overview application, go to your farm and click on the field you want to export data from. Then, change the overlay to Vigor. Once you clicked on the field you wish to export, you should see the Download GeoTIFFbutton on the left hand side.
Once you have that downloaded the GeoTIFF, open up Agleader’s SMS application and click on the Read File(s) icon on the toolbar.
Here, click on the Import a File from a Generic Source icon and then click the Start Importing Generic Files… button at the bottom of the popup.
After, you should ensure that the .tiff file type is selected and the click Select Files(s) to Import… Now, SMS will generate a new popup for you to select the downloaded GeoTIFF TerrAvion file.
This step of the tutorial might differ depending on your situation. On the next screen, select No Clipping - Import Entire Image. The GeoTIFF that you downloaded from TerrAvion following these instructions, should only include the image for that specific field.
Again, these options can differ depending on your specific situation. The image that we downloaded from TerrAvion should just have the NDVI band as the primary band. Thus, often it's appropriate to select Import Image as is and click Next.
Next, select Add to Management Hierarchy and press Finish. This options adds the selected map into the file tree.
After you click finish, there will be a popup screen prompting you to properly categorize your field. You can also set the product type here in preparation for later steps.
Creating Variable Rate Application Maps:
Once your file is imported, select your field on the left-hand sidebar file tree, and then click on the Analysis Wizard icon at the top of the toolbar.
In the popup, you should click on NDVI Analysis, and select Single Field or Multiple Fields, depending on your situation. In this case, we selected Single Field.
On the next popup, ensure all the information is correct and click Next, immediately after this screen, there might be a screen to indicate if you want to delete any unnecessary trees, most often, you do not have to and you can click Next and continue.
There are a couple of options on the next popup, but most often we can select Use Optimal Resolution.
Afterwards, you should have a new NDVI layer ready, if everything looks good, go ahead and save it.
There will be a final popup to ensure all information is entered correctly. In this popup you are required to select a Product, in this case, we select “CORN”.
After the NDVI layer is generated, highlight the NDVI Analysis layer under Analysis Results. Then click Create New Map below the file tree. The newly generated map might be colored all green as default.
After the new map is generated, select the appropriate option from the dropdown on the right-hand sidebar. In this case, we selected NDVI from the dropdown.
Finally, click on the Contour or Grid Icons to create your Variable Rate Application maps. Now your TerrAvion data is ready to use. To import it into your machine, click on the Device Setup on the top toolbar and follow the instructions from your machinery operating manual.
This is how you can use TerrAvion to create Variable Application Rate maps in Agleader’s SMS.
