Planet Fusion

Planet Fusion (PF) represents a novel data fusion framework for combining distributed sensor observations and achieving sensor agnostic analysis ready surface reflectance (SR) data with unprecedented spatio-temporal resolution and consistency. The PF surface reflectance (SR) product adopts an implementation of the CubeSat-Enabled Spatio-Temporal Enhancement Method (CESTEM) to leverage rigorously calibrated public mission satellite data (i.e., Sentinel-2, Landsat 8/9, MODIS, VIIRS) in synergy with higher spatial (~3 m) and temporal (~daily) resolution data provided by Planet's constellation of more than 200 nano-satellites. PF harvests unique traits of distributed sensor data and exploits deep temporal information to effectively integrate and radiometrically and geometrically harmonize the data for full fleet interoperability. PF processing also includes advanced temporally driven functionality related to cloud and cloud shadow masking, and gap-filling to deliver a next generation analysis ready SR product (daily, 3 m) intended as a core "building" block for enabling higher level product development towards timely, usable, and actionable insights ^Planet.

Due to the restriced use of the data for the University Würzburg, the data are only available via private container and private STAC Collection. The availability of Planet Fusion data can be checked via access to private STAC Collection. For the usage of the data, the user license must be accepted. An example how to access restricted data and accept its user licences can be found in the terrapi explanation.
