ndex. NDVI is a graphical representation of the relative vegetation biomass determined by a ratio using near-infrared wavelength (highly reflected by vegetation biomass) and the visible red wavelength (absorbed by vegetation biomass). In Surety, it is displayed in a colors ranging from blue (low) to dark green(high).
The Max NDVI layer uses data from the Sentinel Satellite imagery.
This layer is available within all Surety
®
and Surety
®
Pro subscriptions.
Max NDVI refers to maximum NDVI value recorded during a time period for a given area.
In the case of Sentinel data, the given area is every 10 meter pixel or 100 m
2
The time period in which the NDVI is attained is determined by location and growing conditions
In a contiguous Max NDVI map, all max NDVI values may or may not occur on 1 day, but could occur on several days depending on agronomic and weather conditions.
How to Enable the Maximum NDVI layer
Zoom to the desired map view.
Note: For the Max NDVI layer to appear, the map must be zoomed to at most a 3 mile diameter level.
Then click on Layers in the right panel and locate the Maximum NDVI layer located beneath the
Contour Topo Lines Layer
.
Click Layers to access the layers list
Set the desired Year from the drop down and click on the white box to enable the layer.
The map will be overlaid with the Max NDVI color values.
Show the NDVI color Legend by clicking the Legend link next to the Maximum NDVI layer in the layers panel.
Max NDVI Hillshade
The Hillshade toggle below the Maximum NDVI layer enables a hill shade layer that is produced using topography values. It can help visualize elevation changes.
By clicking on the Hillshade layer link itself, the Opacity and the Vertival Exaggeration can be adjusted in order to appropriately view the hillshade layer in different situations.
The NDVI data layer is also used within the available
NDVI Reports
:
NDVI Hillshade
NDVI Max by Year
NDVI Multi-Year
NDVI Single Date
NDVI Soil Map
These reports can be accessed after selecting or drawing a boundary by clicking on the NDVI link in the Map/Forms list
