DataMapper has recently introduced Triangular Greenness Index app in the DataMapper’s Algorithm Marketplace. Triangular Greenness Index is developed by Exogenesis, an advanced GIS and remote sensing company, the app is a highly specialized and optimized vegetation index.
Triangular Greenness Index app is a simple triangular greenness index for sensing leaf chlorophyll content based on true color imagery. The index was the result of a study to create an index that is sensitive to differences in leaf chlorophyll content at leaf and canopy scales, when limited to true color.

Traditionally, vegetation index readings are used to capture photosynthetic activity and assess plant health, such as nitrogen deficiencies. However, later in the season, they often do not produce accurate results due to saturation as the canopy closes. The Triangular Greenness Index app accounts for this and is additionally not sensitive to pixel resolution, allowing growers to fly later in the growing season by limiting issues with photo stitching and data quality.
