Crop Biomass
AboutCrop Biomass
The Crop Biomass Planetary Variable delivered through the Planet Subscriptions API provides the ability to track and respond to the highly dynamic nature of biomass in agricultural fields throughout the season. This enables better-informed decisions, input optimization, interventions, and harvest planning. This is a relative measure of biomass, so each pixel value has a value of 0 (low biomass) to 1 (high biomass). The product is provided daily and every day, the user gets a new raster with the data from the most updated direct observation from the day before.

Subscribing to Crop Biomass
The Crop Biomass is a field-based data product. This means that each subscription should cover the area of an individual field. In other words, the area of interest should coincide with a field polygon.
To subscribe to Crop Biomass, use the TPDI subscriptions endpoint or EO-Browser's Commercial Data tab with the following type and id values:
| type | id | Description |
|---|---|---|
| biomass_proxy | BIOMASS-PROXY_V3.0_10 | Biomass Proxy V3.0 data product with a 10-meter spatial resolution. The available archive period is from January 1, 2019 to present. |
| biomass_proxy | BIOMASS-PROXY_V4.0_10 | Biomass Proxy V4.0 data product with a 10-meter spatial resolution. The available archive period is from January 1, 2019 to present. |
Available Bands
| Band Name | Description | Physical Unit | Resolution | Source Format | Typical Range | No Data Value | Scale * |
|---|---|---|---|---|---|---|---|
| CB | 10 m resolution Crop Biomass | Relative | 10 m | UINT16 | 0-1 | 65535 | 0.001 |
* The band values are scaled. To obtain the original values, the band values must be multiplied by the scale factor.
Note: All Planetary variable bands are part of BYOC collections. Therefore, their SH units are DN and the column is not present in the table.
Examples
Subscribing to and visualizing Crop Biomass is similar to Soil Water Content, illustrated by this example.
