Planet is a private earth imaging company who provides daily global coverage of the earth at high spatial resolution. Daily images are composted into a weekly basemap based on image quality. Data is collected using a constellation of over 150 individual satellites called doves. Currently, three generations of doves are used in this dataset: Dove-Classic, Dove-R, and SuperDove. Planet data is available using surface reflectance.

Soil Adjusted Vegetative Index (SAVI) is a vegetative index product providing a measure of vegetation viggor while correcting for influences of underlying soil. It is widely used as an indicator of plant health, vegetative cover, drought cycles etc.

SAVI is calculated using the near infrared (nir) and red bands following the equation (nir-red)/(nir+red+L)*(1+L) where L is a soil brightness correction factor which is typically 0.5 (Huete 1988; Ray 2020). This method is useful when there is sparse vegetative cover causing soil brightness to be a significant factor. This method allows comparisons of vegetation vigor over dark and light soils.

Bands Used:
Red: 0.590-0.670 μm
Near Infrared (NIR): 0.780-0.860 μm
