Viewing and Filtering Images

To begin viewing field satellite imagery in Cropwise Imagery, navigate to Map View within the left-side menu.

Next, select the image catalog dropdown to view the list of available images. Cropwise Imagery defaults to Sentinel, 10-meter resolution images which are available for selection every 3 to 5 days on average. Each available image will display one of three cloud presence icons:

Sunny: low cloud presence

Partially cloudy: medium cloud presence

Cloudy: high cloud presence

Highlighting your cursor next to each available image will indicate the cloud presence level. Images can be filtered based on date selection, cloud presence and sources.

Vegetation Index Descriptions

Cropwise Imagery uses the NDVI (Red) vegetation index to visualize plant health across all crop growth stage and agronomic scenarios, but also utilizes Visual view to display the images as the human eye would see them.

Vegetation Index	Vegetation Index Description
NDVI (Red)	The Normalized Difference Vegetation Index (Red) (NDVI (Red)) is the most common index used to measure plant health. The amount of light that is absorbed by the plant is measured from -1 to +1. Non-vegetative objects like roads are calculated in the -1 to 0 range while vegetation is seen in the 0 to +1 range, with 0 being unhealthy and +1 being very healthy.
Visual	Visual, also known as RGB, is what we would see as humans looking down from space. You can use this view when you want to check for clouds or other atmospheric anomalies on your images.

The legend visible in the Map Controls menu is measured from 0 (red) to 1 (green). A vegetation index is used to measure plant health by calculating how much light the plant is absorbing and using for growth. Areas within fields represented from a light green to solid green, index values closer to 1, will indicate a healthy plant biomass.

A plant reflecting more light is a less healthy plant because it is using less light and will be represented with an index value closer to 0. These areas in the field will be typically represented from yellow to red.

Color Palette Adjustment

The color palette can also be adjusted to other predefined palettes.
