Plant Health is a set of tools specifically targeted towards agriculture. The main purpose of these tools is to allow you to explore your agricultural data even more deeply. Using this tool, you can adjust the contrast to highlight variability (and hence problem areas) within a field. Once you have identified the relevant NDVI ranges, the thresholding tool lets you quantify damage and predict yields by showing the area within an NDVI range.
How can I access it?
If you have uploaded data and processed it while on the Free tier of DroneDeploy, you won't have access to the Elevation Toolbox unless it is re-uploaded and processed.
To get started, select
Plant Health from the side panel on the map page.
Plant Health highlighted in red.
This will update the panel on the left to show a histogram of the data and the data itself.
Click on the histogram to explore the plant health toolbox
To adjust this, move the sliding scale bar below the histogram. Here we have updated this to accentuate the differences in the northern section of the field (a different variety of crop).
Adjust settings using the sliding bar
Choose the appropriate color band order that is specific to the filter in the camera. For more information, see our article on Filter Type.
Choose the filter type
We can also select a different algorithm (better suited to different crop varietals) by clicking the dropdown in the top left:
Select an algorithms to process your data.
View of the OSAVI algorithm.
Here we have selected the OSAVI view - Notice how it shows a different view of the same data (although strongly correlated to NDVI), as well as a different histogram.
Grid and Zone tool under Plant Health provides the ability to create higher level management zones from NDVI maps. NDVI management zones in agriculture help make the highly detailed and large NDVI map into a more manageable dataset by grouping similar regions (either geographically or visually) within a field.
For more information, see our article on Zone Management.
