Agricultural Monitoring Workflow Using Geomatica and Free Landsat-8 Imagery
Freely available Landsat-8 imagery can be used as an initial no-cost pass to monitor agricultural crop health, in order to identify potential vegetation stress for commercial farmlands. If indications of stress are identified, analysts can then collect higher resolution imagery such as RapidEye for a more detailed investigation of the agricultural field(s). This helps to ensure that data is only purchased when signs of stress exist. RapidEye imagery can then be used to perform precision farming operations to identify specific areas of stress at a higher resolution to help identify possible causes by deriving more precise indicators of stress, including chlorophyll content – which is a good indicator of nitrogen deprived plants.
