As a PIX4Dfields user, you can connect a John Deere Operations Center account with PIX4Dfields and upload orthomosaics, reflectance maps, vegetation indices, zonation, and prescription maps to the John Deere Operations Center.
Note: PIX4Dfields outputs such as Orthomosaics, Digital Surface Model, and Index maps are exported as a GeoTIFF file. See PIX4Dfields inputs and outputs. Different Farm Management Systems support GeoTIFF files. Please refer to your Farm Management System about their supported formats.
