Why is satellite imagery important for agriculture? Copyright NB Spatial Solutions 2007 All rights reserved • Wide range of satellites cover vast areas virtually anywhere on earth’s surface (different scales) • Imagery can be acquired at regular intervals through programming • Rapid processing of imagery provides near-realtime information • Multi-spectral information yields useful value-added products to: - Show in-field variability - Detect stress factors - Monitor crop development - Establish historical reference database for benchmarks and comparisons - Evaluate management actions - Provide early yield estimates • This information assist growers to make better informed decisions • Integration of satellite imagery with other digital technologies = powerful precision farming tool to make better informed decisions
