NICFI data to earth engine

Google Earth Engine, Python One comment

Small python script to automatically ingest the data to asset

With an api key you can get the NICFI planet data and push it to earth engine

Please note that the current script copies the data to a Google Cloud Bucket and then ingests it to the earth engine. You might be charged for this operation.
