Abstract: A system for agricultural monitoring and prediction comprises a first reporting agent a second reporting agent a database, and a processor. The first reporting agent is configured for reporting aerial data representing relative measurements of an agricultural metric in a geographic area, the relative measurements having an unknown bias. The second reporting is configured for reporting ground-based data representing absolute measurements of the agricultural metric for a portion of the geographic area. The database is configured for storing the absolute measurement data and the relative measurement data along with other farming data for a wide geographic area. The processor is configured for accessing the database and using the ground-based data for the portion of the geographic area to calibrate the aerial data, thereby synthesizing absolute measurements of the agricultural metric for the geographic area from the aerial data.
