Introduction
Agricultural Big‐Data projects in Japan
• Social Big Data Platform Project (2014‐2018)• National Institute of Information and Communications
Technology (NICT)
• CREST (2016‐2022)• Japan Science and Technology Agency
Field Sensing using UAV
Experimental field Actual fields
Field Monitoring by UAV on farmers’ fields
Tokachi Area in Hokkaido(Large-Scale Farming Area in Japan)

UAV flight plan (2015)
Target: 5 fields (25ha)Date:5/25, 6/2, 6/10, 6/19, 6/25, 7/2, 7/10, 7/16, 7/24, 8/7, 8/19, 9/3, 9/15, 10/6 (14 times)
Camera:SONY α6000 (ILCE‐6000), 4000x6000 pixels, 350dpi
Flight altitude:100mGround speed:7‐8m/sShooting interval:2sec eachGround resolution:2.5cm

Summary
• To shoot image by UAV is not so difficult• Automatic flight• 10min for 5ha field
• To manage image data is very hard• Takes many hours to gain orthomosaic image• Big storage, Powerful CPU
• Improve farming?• Decision support system?

Summary
• We could operate UAV in various environments• Generate flight plan automatically• Automatic operation• Experimental fields, sloping fields
• 3D reconstruction, many problems to be solved• Breeding fields• Sloping orchard
• High resolution images are desirable• General cameras are not enough
Future work
• The key is high‐resolution images• How to flight• Which equipment we should select
• Environment for BigData management• Storage• Database• System to create metadata
• Environment for data analysis• 3D reconstruction• ….
