26 Jan Sentera Offers First NDVI Crop Health Maps Showing Field Contrast and Progression
NDVI Toolbox for AgVault Offers Unprecedented Insights into Field Vigor
Sentera announced the release of NDVI Toolbox™ for its AgVault™ software platform: a set of tools for customizable Normalized Difference Vegetation Index (NDVI) data that give growers and agronomists significant insight into field and crop health, today and throughout the season. Users can recolor, dynamically regenerate, and highlight areas of an NDVI crop health map, on current data and on historical data. The NDVI Toolbox is now a standard feature of Sentera’s AgVault Pro and Viewer software licenses.
“Until now, you needed to choose between viewing data tailored for NDVI progression over time, or tailored for NDVI contrast around a single flight — but, you couldn’t do both,” said Greg Emerick, Executive Vice President for Sentera. “We changed that. Now, growers and agronomists have that flexibility. They are more in control of their operations, and can make even better decisions, even faster.”
Why this matters
NDVI essentially compares one area to another, illustrated with color. If a crop is generally healthy, it appears bright green on a NDVI map. This is generalized data, however, and is only useful in general terms. AgVault’s NDVI Toolbox makes that data actionable by building flexibility into the color map. Instead of blanketing an NDVI map with low variation of a single color, the NDVI Toolbox allows you to force dramatic color variations to show a plant’s health relative to others in the field at a granular level.
Fly once and zoom in on areas of concern in AgVault, and assign a wider variation in color value for easier analysis; the average person can identify areas of stress, compaction or drown-outs. Fly multiple times and see problem areas as they emerge. Perpetual problem areas can be investigated and remedied effectively — users can even go back to previous flights to see when issues emerged. Or re-analyze data from the past in different ways.
“Every time you fly with an NDVI sensor and collect data, AgVault catalogs the data and the NDVI Toolbox becomes more robust, offering increasingly accurate data,” remarked Reid Plumbo, Director of Product Management for Sentera, “Over time, it just gets better and better.”
AgVault’s NDVI Toolbox features two viewing options:
- Day to Day – Growers can monitor and compare a field over time, highlighting changes from one day to the next. The Day-to-Day view ensures growers can pinpoint areas that have flourished or become stressed over time and take action. Multiple data sets build on one another.
- Acre to Acre – Allows growers to determine the overall vigor of a field, identify problems, and take action. This is all completed with a single data set.
“Our customers have been asking for this exact solution, and we’re honored to have brought this answer to the precision ag industry,” said Plumbo.
The NDVI Toolbox is available now with Sentera’s AgVault Pro and Viewer software license options.
