Introduction to Zonal Statistics

Zonal Statistics in Solvi allows you to divide an Upload into multiple zones and calculate various metrics for each of them. These zones — often referred to as plots in field trials — are the foundation for detailed, plot-level analysis.

The tool is particularly useful in agricultural research, variety testing, and other field experiments where results are compared across many small plots within the same area.

Typical Applications

Zonal Statistics is most commonly used for:

- Defining microplots in field trials to analyze treatment differences

- Calculating vegetation indices or other spatial metrics per plot

- Exporting plot-level data for statistical analysis in other software

Where to Find the Tool

The Zonal Statistics tool is available inside the Analysis tab in each individual Upload. Once an Upload has been processed and opened, go to the Analysis tab and select Zonal Statistics. From there, you can create new zones, manage existing ones, and run calculations for the selected dataset.

Overview of the Workflow

The workflow consists of three main steps:

1. Create or load zones or plot boundaries using one of several available methods.

2. Choose desired metrics and run the Zonal Statistics calculation to generate plot-level metrics such as mean vegetation index values.

3. Review and export results as CSV or Shapefile for further use in other analytical tools.
