Maximum NDVI and Hillshade Layer

Modified on 2020/10/06 18:11 by Adam — Categorized as: Features, Map Layer

NDVI stands for Normalized Difference Vegetation Index. 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 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.

The NDVI data layer is also used within the available NDVI Reports:
These reports can be accessed after selecting or drawing a boundary by clicking on the NDVI link in the Map/Forms list
