# Overview

> Live readings, alerts, field health, zones, NDVI, growth stage and the 7-day forecast.

Field Monitoring is the field's own page: what the soil is doing now, what the canopy looks like from above, what stage the crop has reached, and what the week's weather will do to it.

Readings come from an [AgriHub360 Sensor](/devices/sensor) or a device you connect. Weather and satellite imagery come from public sources. Everything is drawn on one timeline, so a reading, a forecast and an image can be read against each other. Every alert names the reading behind it.

The timeline drives the alerts and the field health review.
