• Wide range of satellites cover vast areas virtually anywhere on earth’s surface (different scales)<br />
• Imagery can be acquired at regular <strong>in</strong>tervals through programm<strong>in</strong>g<br />
• Rapid process<strong>in</strong>g of imagery provides near-realtime <strong>in</strong>formation<br />
• Multi-spectral <strong>in</strong>formation yields useful value-added products to:<br />
- Show <strong>in</strong>-field variability<br />
- Detect stress factors<br />
- Monitor crop development<br />
- Establish historical reference database for benchmarks <strong>and</strong> comparisons<br />
- Evaluate management actions<br />
- Provide early yield estimates<br />
• This <strong>in</strong>formation assist growers to make better <strong>in</strong>formed decisions<br />
• Integration of satellite imagery with other digital technologies = powerful precision farm<strong>in</strong>g tool<br />
to make better <strong>in</strong>formed decisions
